An Analysis of Solar Powered Irrigation Systems

If you’re reading this, you probably already know that solar powered irrigation systems will change the way farms are irrigated. But it isn’t just a simple change in power source to solar energy.  It’s more akin to revamping the entire irrigation system on the farm.

The two main benefits of installing a solar powered irrigation system are to:

  • Significantly reduce the time required to irrigate crops
  • Simultaneously cut down on water consumption

Solar powered irrigation systems combine clean and cheap solar energy with technology to produce a system that is energy conscious, performance orientated, and creates zero waste. It does this by using solar panels, controllers and water pumps to deliver the exact amount of water, exactly when it is required.

The Parts of a Solar Irrigation System

A solar irrigation system consists of a host of different parts, and some water pumping systems are more complex than others. All solar-powered water pumps consist of the following components.

Solar Panels

The main component in any solar-powered pumping system is the solar panel itself. A solar panel is a collection of photovoltaic cells that absorb the sun’s rays and convert them into direct current, which is then converted to alternating current at the motor. These cells are usually made of crystalline silicon, and mounted on a supporting structure. This combination of photovoltaic cells and supporting panels create a solar PV. These panels are extremely durable, and only see about a 2% drop in effectiveness a year, which can further be reduced if preventative maintenance is done often.

There are three types of solar panels commonly used in solar irrigation systems:

  • Monocrystalline
  • Polycrystalline
  • Thin-film panels

Monocrystalline and polycrystalline panels are use silicon shards, with the difference being that the former is created using a single piece of pure crystal silicon. In contrast, the latter is made up of crystals melted together from different fragments of silicone. Thin-film panels use a combination of materials that enable them to capture sunlight.

Monocrystalline panels are the most expensive, but also perform the best. They can reach efficiency levels of up to 20% and can produce 400+ Watts of power. In comparison, polycrystalline and thin-film panels reach efficiency levels of 15% and 11%, respectively, and can both produce around 300 – 400 Watts.

Solar Water Pump

In solar water pumping, centrifugal pumps are used almost exclusively. These solar irrigation pumps use an impeller to rapidly spin water inside the casing, which pushes the water towards the area of the casing that leads to the outlet.

There are two main types of solar water pumps used in solar irrigation: submersible, and line-shaft pumps. Each has its advantages and disadvantages.

Submersible Pumps

Submersible pumps are centrifugal pumps that contain the pump and motor in a single waterproof unit. As the name suggests, the entire unit is submerged in the water source. Because it’s below ground, these pumps are quiet, which is advantageous for farms that are close to buildings.

Submersible solar pumps have fewer parts than line-shaft pumps, which means they vibrate less. This helps reduce overall wear and tear on the unit. These types of solar water pumps can also be more cost-efficient in certain instances, since they don’t have any line-shafting. The caveat is that they require more intricate power cables, which could render this point obsolete.

Because the motor and the solar pump is encased in a single unit, submersible solar water pumps tend to be smaller and more manageable to handle in terms of transport. And since the solar pump sits underground, it doesn’t need a pump house to protect it from the weather, which can be an eyesore.

Line-Shaft Pumps

A variation of a centrifugal pump, the turbine pump has a pump mounted underwater, while the motor is above the water. These solar pumps are used for large-scale operations where they cannot be submerged inside the source of water, typically because the space is too small for a complete solar pump to be submerged in.

Surface pumps have clear advantages over their submersible counterparts, with the first being efficiency when pumping water. The motors on surface pumps tend to be roughly more efficient than submersible pumps. This can be mitigated, however, as the depth increases since this set-up loses around 2 horsepower per 100 feet due to the friction that affects the shaft.

Line-shaft solar pumps are less likely to fail than submersible pumps and tend to handle fluctuations in electricity well, while submersible pumps are susceptible to low voltage conditions, and overload easier than line-shaft pumps during power surges. One of the main reasons surface solar water pumps have a lower failure rate than submersible pumps is because the latter operates in a harsher environment. The sand and soil, along with the high pressures, wear out the electric motor waterproof seal.

Since they are installed at ground level, line-shaft pumps are much cheaper to install, inspect, repair, and maintain. Any time a line-shaft pump fails, you simply replace or repair the component that failed. With a submersible pump, you need to uproot the entire unit to repair it.

In conclusion, a submersible solar water pump is best suited for more urban areas where noise and aesthetics must be taken into consideration. This type of solar pump can also be used in areas that would cause vibration issues for line-shaft pumps, whereas the main selling point of line-shaft pumps is their high efficiency and reliability, which is more fitting for rural areas.

Battery Array

While it isn’t a necessity and some solar pumps do not have one, including a high-capacity battery array in the irrigation set-up will allow for uninterrupted usage when there’s not enough solar energy due to the weather or other unforeseen circumstances. Battery arrays are fail-safes that are not often used, as solar power is quite reliable. But when crops are on a strict irrigation schedule, having a battery array can be extremely helpful.

Battery arrays are expensive, however, and adding one in a solar water pumping system will increase the price, as well as introduce another potential point of failure. The battery array has a secondary use, however. The excess electrical energy generated by the irrigation system can be stored in the batteries and used for other operations on the farm. This reduces overall operating costs and could potentially even offset the cost of the battery array.

Controller

Solar-powered irrigation systems are designed to manage power consumption and water consumption. To achieve this, the system is built around a controller. The controller serves as the brain of a solar powered irrigation system, and has functions that can be configured to the end users unique requirements. For example, the following are 2 common configurations:

  • The point at which the panels should stop charging the battery and focus solely on the irrigation process
  • Below what power level the battery should kick in

One of the most important features of a solar powered irrigation system is that it can be operated automatically and without supervision. The caveat is that additional components are needed in order to do so.

The more basic version of automation is to use a timer, where the user manually schedules at what time the system discharges the water, as well as for how long. This scenario works well for most systems and crops. If crops are more sensitive or water has to be conserved, however, it can also be equipped with sensors that detect the level of moisture in crops. What this means is that the system will turn on the sprinkler system and pump water when that value drops below a predetermined level. A moisture sensor automates the solar water pumping and irrigation process, so that crops are watered efficiently.

Irrigation System

 

There are a variety of irrigation systems that can be solar powered:

Localized Irrigation systems

use low-pressure water distributed over a system of pipes, and are best used in small-scale operations.

Sprinkler Systems

Deliver water by spraying it over the top of the field, which results in more coverage. A more advanced version of a sprinkler irrigation system is a center pivot system, where multiple sprinklers are positioned on wheeled towers. Sprinkler irrigation systems can cover large areas, but are susceptible to overspray and evaporation, which makes them much more inefficient in comparison to some localized systems since evaporation and overspray mean more water waste.

A Drip Irrigation System

Is one of the most efficient, and pumps water by delivering droplets to the roots of plants via quite a bit of plumbing. Since the water is distributed close to the plant, evaporation is kept to a minimum. There is also no overspray, which can result in up to a 90% increase in efficiency in comparison to sprinkler systems.

Supporting Components

Supporting components must be used for an irrigation system to function, whether they are solar-powered or not. For example, storage tanks are used to temporarily store the water that is pumped up from the source, as well as water from sources like rain, until its use in the next irrigation cycle.

The plumbing that is used must be of high quality when setting up a solar-powered irrigation system. This reduces maintenance costs, as leaks can cause substantial amounts of damage. The same holds true for electrical systems.

How to Choose the Right Equipment

Water and power requirements differ from farm to farm, and must be calculated when trying to determine what equipment will be best for the job, while still maintaining cost-efficiency. The key thing to keep in mind is that the main components of a solar irrigation system that affect performance and cost are the water pump and the solar panels. While most systems come standard with a combination of the two that will work, there could potentially be a solar panel setup that works better with a specific water pump that is a better option depending on end-user needs.

There are two main metrics to consider when deciding which type of water pump will be needed on a farm: gallons per minute and required pressure. Whatever water pump is used must meet – and exceed – the requirements to ensure that the pump will not be damaged if there is a failure elsewhere. The two types of pumps, submersible and line-shaft (surface), come in two configurations:

  • Flow pumps are useful for low-pressure irrigation systems like drip systems, have a massive maximum flow rate, and take up less power than pressure pumps. This lack of pressure, however, prevents the water from being pushed through filters. If the water source is clean and does not require much force, flow pumps are the way to go.
  • Pressure pumps, on the other hand, have high pressure and a low rate of flow. They are used for sprinkler-type irrigation systems, or in situations where water must be moved large distances or through a filtration system.

When choosing a solar panel for the system, if:

  • Saving space and energy costs is important, monocrystalline panels are the way to go since they produce the most power
  • Weight must be taken into account and costs must be restricted, a thin-film panel can be used
  • Space is not an issue, and initial costs need to be kept down, polycrystalline panels are the best option

Surveying The Location

When attempting to install an irrigation system, solar or otherwise, the farm must be surveyed to determine what options will be best for how the system is set up. For example, in farms that use diesel pumps, there’s a very real possibility that the entire system will need to be uprooted, which might not be feasible. Other factors like power draw could also be an issue, since solar pumping isn’t the most powerful method of pumping water, and the system might struggle to pull irrigation water from the water supply.

If land in southern Asia is to be surveyed for solar-powered pumps, keeping the dry season in mind is important, since a solar water pump might not be powerful enough due to such a low water table. The flip side is that the sun shines there for longer, which means the system can capture a large quantity of the sun’s energy and operate at maximum capacity, allowing the system to be built larger than it normally would be.

If a solar irrigation system is going to be installed, further choices have to be made. For instance, will the water pump be land-based or submerged, and what type of irrigation system will be used? Sprinkler systems that cost less are good for larger areas, but they waste water. Drip style systems, on the other hand, require more plumbing and are therefore more costly, but most effective for smaller areas.

The Bottom Line

Solar-powered pumping systems are environmentally friendly, growing in popularity across the entire world, and starting to replace both diesel-powered and grid-powered systems, particularly in areas that lack a regular supply of water. They also help farmers reduce costs and revamp their outdated systems, which require more maintenance and are less efficient.

Over the last two decades, the average cost of solar panels and other components in solar powered water pump systems has become cheaper and easier to attain, especially with the assistance of government subsidies. These systems do have limitations, but they can be circumvented with little effort, and using them is the perfect solution to the persistent irrigation problems.

Renewable Energy Legislation to Revive PA Economy

A coalition of organizations has rendered their support for the new renewable energy bill that was introduced by Senator Art Haywood and Senator Daniel Laughlin. The legislation will help to harness the power of renewable energies like solar, which will put Pennsylvania back on the road to economic recovery.

The senator’s bill will amend the 2004 Alternative Energy Portfolio Standard (AEPS) Act to increase PA’s renewable energy goal from 8% to 18% by 2026. 5.5% (from the current 0.5% goal) of renewable energy is set to come from solar energy.

Introducing The Legislation

When introducing the legislation, Senator Laughlin said that it would help expand renewable energy given that the economy is in a crisis due to the COVID-19 pandemic. He went on to say that the efforts will diversify the energy mix, attract private investments worth millions of dollars, create tens of thousands of jobs, and grow tax revenue for communities.

He also said that this might offer a solution that can save farms in PA without necessarily using state revenues. Similarly, Senator Haywood said that renewable energy grows jobs, saves farmers, and can do a lot to save the planet. He added that the proposal might be one of the largest job stimulus and economic development bills in decades.

Renewable energy is one of the fastest-growing industries in the nation. When compared to the statewide job growth rate of 1.9%, jobs in the renewable energy industry grow at a rate of 8.7%.

Nearly 5,200 jobs have been created in this industry since the Alternative Energy Portfolio Standard Act was passed in 2004. PA renewable energy projects have created jobs for engineers, technicians, construction workers, manufacturers, salespeople, and more.

Finding Pennsylvania Solar Future Project estimates that more than 100,000 jobs will be created by 2030 should the portion of solar in the state’s electricity mix increase from the current 0.5% to 10%. Consequently, this will benefit the economy with a net of $1.6 billion annually.

Here is what some of the coalition members had to say:

Sharon Pillar, who is PA Solar Center’s Executive Director, said that there is a high expectation for the bill to put back PA on the road to recovery after the hard times experienced in 2020. She also thanked the two senators for introducing the bill and providing inspiring leadership on renewable energy.

Kim Anderson, Evangelical Environmental Network’s field organizer, said that he is excited about the bill. Anderson said that the bill moves in the right direction when it comes to embracing cleaner energy and air to protect the health of both born and unborn children.

Executive Director of PennEnvironment, David Masur, said that promoting renewable energy gives a triple win for PA. He said that it is good for the health, pocketbooks, and the planet. David further said that it was about time PA became a regional leader when it comes to tapping into the renewable energy economy.

Pennsylvania Program Director at Solar United Neighbors, Henry McKay, said that Pennsylvanians in both urban and rural communities in the entire Commonwealth prefer to go solar. He said that they want to decrease their electric bills and be in charge of how their energy is generated.

Henry said that increasing the value of solar renewable energy credits will contribute to a stronger AEPS that will enable more businesses, homeowners, and places of worship to afford solar installation.

8 Community Choice Aggregators Join Forces to Purchase Power Through California Community Power

Community choice aggregators (CCAs) in Northern and Central California have joined forces to form a new Joint Powers Authority (JPA). The new JPA will include Central Coast Community Energy, MCE, East Bay Community Energy, San Jose Clean Energy, Redwood Coast Energy Authority, Sonoma Clean Power, Peninsula Clean Energy, and Silicon Valley Clean Energy. According to the group, CleanPowerSF and San Francisco’s CCA are seeking membership.

What is Community Choice Aggregation?

Well, let’s have a quick look at the video below:

The JPA makes it possible for the 8 Community choice aggregators to join their buying power to procure large-scale, cost-effective, and clean energy to meet the climate goals at the local and state levels. The combined buying power will also offer cost-effective programs and services.

Community choice aggregators have become a major player in the electricity markets in California. The CCAs are tasked with supplying electricity from the state’s investor-owned facilities to millions of customers. As the 8 CCAs come together, their goal is to buy large amounts of clean energy to advance climate goals.

The new group that forms California Community Power serves about 2.6 million customer accounts. In total, the CCAs serve an annual load of 32 600 GWh, which is about 40% of what the Northern California utility Pacific Gas & Electric serves.

According to a senior solar analyst at Wood Mackenzie, Colin Smith, this makes the joint buying group one of the biggest purchasers of power in the country. The group also serves about 6.6 million customers in more than 140 municipalities from Humboldt County to Santa Barbara County.

The group will allow different aggregators to collaborate on bigger energy procurements, which they would not have handled separately. This is especially true for smaller and new CCAs who may have difficulty getting financiers for their power projects.

However, joining forces with larger CCAs with investment-grade credit ratings will give them greater leverage, better deals, and confidence from developers. Other benefits of the JPA include increased innovation opportunities, enhanced negotiating power, shared risk mitigation, and greater procurements for renewable and storage.

In October, seven CCAs in the California Community Power and another CCA announced a request for offers for long-duration storage. The long-duration Request for Offers comprises a contract of at least 10 minimum for grid-charged technologies with a minimum discharge period of 8 hours to come online by 2026 or before.

According to the state regulators, the long-duration storage procurement is supposed to meet the clean energy goals of California. The JPA is currently steering that process for its seven members.

Public Participation on Low-Wealth Solar Policy Roundup

Policymakers and local communities across the U.S. are redesigning the solar policy to incorporate low-wealth families as major stakeholders to help them benefit from local clean energy.

Each month, Emphasis Power initiates a Low-Income Policy Call, which is led by our Access & Equity team. During the call, we bring together policymakers from across the country to celebrate our wins, talk about best practices and advanced learning, and brainstorm ways to join forces to improve on the design of the low-income solar program.

We believe that by hosting this call, we will be able to address some of the greatest issues that lower-income communities face. We use it to share information on the best practices that are working and those that are not so as to ensure that affordable solar is easily accessible to everyone.

Congress Directs FERC to Form Office of Public Participation

The policy must not just be informed by regulatory and legislative action alone. Instead, the public must be encouraged to offer their input; otherwise, there will be knowledge gaps and goals will be misaligned.

Many people in the community wonder how they can participate in the decision-making process. Unfortunately, they are faced with various barriers. This has prompted the federal government and states to brainstorm effective ways to increase public participation.

Congress has asked the Federal Energy Regulatory Commission Office to establish an Office of Public Participation. FERC, which was formed in 1977, is an independent regulatory agency that is tasked with regulating the interstate transmission of electricity, oil, and natural gas.

FERC announced that there will be a workshop and a series of listening sessions to allow interested persons to offer input on the establishment of the Office of Public Participation (OPP).

The OPP, which will be within FERC, will offer assistance to interested parties of the public that want to participate in Commission proceedings. This will be done per the authorities that the Commission exercises.

La Mesa Prepares to Launch Community Choice Power Program

La Mesa has partnered with four other cities to prepare the launching of the community choice energy program. The program is intended to provide a transition from renewable sources to clean energy to approximately 770,000 customers in La Mesa, San Diego, Imperial Beach, Encinitas, and Chula Vista.

The SDCP (San Diego Community Power) is set to be the second-largest CCA (community choice aggregation) program in California.  This program will be locally run and proponents believe that it will be the solution to providing the community with 100% renewable and cost-effective energy.

According to the California rules, San Diego Community Power customers will automatically be enrolled in the CCA program. Despite the establishment of CCA, incumbent power companies like SDG&E will continue to operate and provide services that are not associated with power purchasing.

This includes tasks such as customer billing and transmission and distribution of energy. SDGE will be responsible for purchasing renewable energy and then feed the energy into the electricity grid that is maintained by SDG&E. Besides, customers that prefer to remain with SDG&E can come out of San Diego Community Power (SDCP) for free.

David Harris, who is a resident of La Mesa and a member of the group’s 10-member Community Advisory Committee, expressed his gratitude to the city for publicizing the importance of San Diego Community Power to the city.

He also thanked the city of La Mesa for consenting to community choice energy for La Mesa in 2019. Harris said that once the program is launched, San Diego Community Power will give 50% more renewable energy to the electric grid compared to the SDG&E.

Harris said that the surplus revenue that San Diego Community Power will generate will be reinvested back to the community. This, he said, will create local jobs for skillful workers and fund renewable energy products.

According, Bill Carnaham, San Diego Community Power Interim Chief Executive Officer, the rates and service offerings will be structured such that they are in line with San Diego Gas & Electric.

During a presentation at La Mesa City Council, Carnaham and Cody Hooven, who is the Chief Operating Officer at San Diego Community Power said that one of the group’s goals was to attain 100% renewable energy by 2035. Attaining this goal will also help La Mesa to meet its goals of greenhouse gas reduction as stated in its Climate Action Plan for 2018.

Carnaham said that SDCP will send two notices to customers before they are enrolled and the other two notices after the service begins. The notices will include information that allows customers to opt out if they want to.

As aforementioned, the enrolment in the program is automatic. However, participation is voluntary. This is according to the statement of intent of the SDCP group that was filed in December 2019 with the California Public Utilities Commission.

To make the launching possible, the City of San Diego allocated half a million dollars from its 2019-2020 budget to support the program. The group has also taken a $30 million working capital loan and a $5 million bank loan for the purchase.

Energy Saving: EBCE Comes Up with Holistic Approach to Energy Saving

The EBCE is taking steps towards achieving a zero-emission power system in the next decade. Despite this move, one of the challenges is the evening peak. While it is easy to meet the power demand in the daytime when the sun is up, it becomes a challenge in the evening when the sun goes down.

There is a need for something else to meet the demand in the evening hours. The peak hours are expensive times for EBCE customers to buy power. However, the most viable solution that can help fill the gap is to burn natural gas. This can be a setback since it is not zero-emission.

Pay for Performance

To ensure energy saving, EBCE has come up with a new approach known as Pay for Performance. EBCE uses this approach to compensate energy efficiency contractors depending on their capabilities to cut or reduce demand in the evening hours. The approach is also set to give verified savings to targeted customers.

By saving energy during peak hours, EBCE will help save money for everyone. EBCE developed pilot programs for the Pay for Performance approach in 2019, which was intended for low-income residential customers, single-family residential, and commercial customers.

In-house Data Capabilities

To help with the entire process, EBCE hired the Recurve Company, which was responsible for developing a dashboard that builds on the in-house data capabilities of EBCE. The dashboard helps to analyze customer loads comprehensively. It then creates baselines and keeps track of how the loads change based on the energy measures.

For EBCE to get the highest value, a constant stream of sub-hourly data from the smart meters is constantly fed into the dashboard. This also allows EBCE to reach customers that would greatly benefit from the program.

Generally, a red dotted line will represent the general population and a blue line for those with high demand during peak hours. The program makes it easy to filter customers with high demand during peak hours from the general population. Consequently, the program is now able to target customers that have the most potential to save.

The Low-Income Pilot

According to the program manager for building electrification and energy efficiency at EBCE, Beckie Mentem, the low-income pilot has enabled them to identify customers on rate discount programs like FERA or CARE that utilize massive energy during peak hours low-income pilot.

She went on to say that some households in the low-income category use nearly 12% of their income on energy. This, she says, is higher than what most wealthy customers use. Basically, the program will help customers lower the proportion of their energy use to their monthly income, helping them save on their energy costs.

Mentem was quick to note that providing efficiency improvements meant for cutting the demand during peak hours will significantly lower their bills. It will also ensure a seamless time-of-use rates transition set to phase this year and lower the need for EBCE to provide power during peak hours. She said that this would help save money for all their customers.

Advocates Against Indiana Move to Curb Solar

On Wednesday, the Indiana Utility Regulatory Commission (IURC) gave a ruling that will see customer-owned solar inaccessible for Vectren customers. The move will reduce the credit that future-solar owners, who are served by Vectren, will receive. IURC decision will also change the period for earning credits, meaning that customer-owned solar will be credited at the new lower rate.

The IURC oversees five investor-owned utilities in the state including Vectren Energy, Indiana Michigan Power, Duke Energy, Northern Indiana Public Service Company, and Indianapolis Power and Light.

The INA broad alliance of solar, environmental, and consumer advocates of Indiana have condemned the ruling.  According to the advocates, the decision is a great setback for the customer-owned solar market in Indiana. The coalition of advocates has put a lot in environmental and consumer outcomes in regions like Indiana, the Midwest, and the nation.

The ruling will solidify the monopoly of CenterPoint and this will be a major setback for customer-owned solar in the territory. It will have a negative impact on the consumers in Southwest Indiana.

In 2015, Indiana lawmakers tried to pass a bill that aimed to decrease the payback for net-metered solar. The bill also aimed at allowing state utilities to add new bill charges. However, the bill was pulled down before it could even reach a vote.

The solar industry and advocates are concerned that the ruling favors monopolies and puts unfair burdens on rooftop customers.

According to Indiana Program Director at Solar United Neighbors, Zach Schalk, solar owners are entitled to fair value as compensation for the electricity they generate. Zach said that rooftop solar harvests sunshine to give clean electricity, which benefits all customers.

He went on to say that they are disappointed by the IURC’s ruling to protect the monopoly profits of Vectren at the expense of Hoosier. He believes that the IURC should have stood up for the consumers by supporting rooftop solars.

In response to IURC’s rulings, Kerwin Olson, who is the executive director at Citizens Action Coalition of Indiana this is another scenario of the consumers losing at the IURC and the monopolies winning. Kerwin said that it is shortsighted decisions like the one IURC made that continuously leave Indiana consumers behind and entire Indiana in the dark for ages.

A senior attorney at Environmental Law & Policy Center, Brad Klein made his remarks saying that they are very disappointed that the IURC chose to prioritize the profits of Vectren over the interests of its customers. He went on to say that the decision of the IURC is contrary to Indiana law.

Emphasis: Power’s Regulatory Director, Thomas Brown said that the move is a setback for Indiana and its community. He said that families and businesses in Southern Indiana desire to have clean energy but this is proving difficult because of the IURC decision.

He said that the ruling prevents fair compensation for companies that have invested in local solar. He was also quick to note that Indiana was moving backward as parts of the Midwest invest in clean energy and take steps to modernize electric grid.

Ultimately, there is no denying that curbing customer-owned solar will cripple the solar industry that serves them as well. It limits the customer’s choice when it comes to their source of energy and their ability to be self-sufficient. Solar installers are arguably the fastest-growing jobs in the U.S and a good number of the jobs are in Indiana.

However, with the move to curb solar in Indiana, installers may need to expand their business to other states to be able to survive. Businesses may be forced to move their businesses to other states or lay off employees.

Solar Customers in Kansas Will Get Refunds

The Kansas Corporation Commission (KCC) held its regular business meeting on April 8, 2021. During the meeting, the corporation voted unanimously requiring Evergy to give refund to solar customers.

According to the order, the commission reviewed the legal authority that was mentioned by the Solar Group and was convinced that the solar customers are entitled to the refunds. The commission requires Evergy to give refunds to the DG solar customers after the company placed them on the Distributed Generation Residential Standard rate. This was based on what the customers would have paid on the Residential Standard rate.

The chairman of the commission, French said that it was important to consider new ways to address the issue. He went on to say that other states have considered the value of Solar Studies and this approach has worked well since it does not assume an outcome.

Commissioner Susan Duffy also echoed the same sentiments saying that she hoped the parties would use this time to consider more modern ways to tackle the issue. Based on the order, it was clear that the commission requires the stakeholders to come together and look for a holistic approach to move forward.

Solar advocates also requested to allow solar users to choose any Residential Standard rate. Following this, Evergy agreed to the request to allow solar customers to choose any rate.

However, the company made an exemption of the Time of Use (TOU) pilot saying that there would be difficulty with the rate and the net metering. The Kansas Corporation Commission approved their offer.

The Commission also made remarks regarding the Petition for Reconsideration and Clarification by Electric Companies. The Commission said that only an added service like exporting would be justified for an added fee like the proposed grid access charge. This, therefore, means that Evergy will not charge their solar customers discriminatory charges moving forward.

Apart from the Evergy Central customers, we also believe that the demand charges should also be removed for their other Kansa customers. Emphasis: Power is committed to working with the commission to ensure solar power is made accessible in Kansas.
