The Mississippi Public Service Commission in a bipartisan vote has approved amendments to the former Net Metering and Interconnection Rules, now referred to as the Net Renewable Generation Rules. The newly adopted rules include policies that look to increase solar adoption across the board, enhancing grid reliability and economic development, in addition to improving access to solar for low- and middle-income residents.
Net generation is a billing practice that allows property owners with distributed generation (DG) capacity from solar panels or wind turbines to sell their excess generation capacity back to the grid in the form of credits. This docket was opened in January 2021, pursuant to the reopener directive of the original December 2015 Order Adopting Net Metering, in order to contemplate necessary revisions to the Rules.
After opening the docket, multiple parties filed written comments, which were reviewed by the commission and incorporated into a draft rule that was published both in this docket and with the Secretary of State in January of this year. Additional written comments were solicited and reviewed, and a public hearing was conducted immediately following the open meeting on March 1. After carefully considering all of the written comments, as well as the testimony presented at the public hearing, commission staff have prepared a Final Order Amending the Rules.
The names of the rules and terminology throughout the rules were amended to reference Net Renewable Generation as opposed to Net Metering. These changes were made to better reflect the type of distributed generation program made available under the rules, which is not traditional net metering, but rather a more general compensation program for behind-the-meter distributed generation.
The order retains the 2.5 cents/kWh Distributed Generation Benefits Adder, but grandfathers it in for a period of 25 years. The low-income benefits adders is likewise grandfathered in for 25 years.
Eligibility for the low-income benefits adder has been expanded to include customers with annual household incomes of up to 250% of the federal poverty level.
The rule now includes a meter aggregation provisions, which allow customers with multiple meters to use the energy generated by one distributed generation (DG) system to offset their usage on all eligible meters. To be eligible for aggregation, all meters must be located on the same premises or within the service area of the customers’ current electrical provider.
DG customers are no longer required to transfer RECs to their utilities as a condition of receiving the 2.5 cents per kWh Distributed Generation Benefits Adder; However, if a customer elects to receive an up-front rebate, that customer may be required to transfer their RECs as a condition of receiving the rebate.
The definition of net generation has been revised to note that special metering requirements are obviated with the use of advanced metering infrastructure / smart meters. The rule now expressly states that battery storage systems shall not affect the total nameplate capacity of a customer’s DG system. System capacity limits under the rule will now be measured in terms of alternating current rather than direct current.
The previous hard 3% participation cap has been modified and increased. Now, utilities may seek commission approval to refuse additional DG customers if and when participation reaches 4% of the utility’s total system peak demand.
Similarly, rather than including a reopener provision, the rule now mandatory permits the commission to exercise its discretion in deciding whether to reopen the rulemaking for additional changes at the earliest of either 5 years from the date of this order, or the point at which total net distributed generation capacity reaches 4% of the utilities’ system peak demand.
In addition to these amendments to the Rules themselves, the Order sets forth provisions instructing the utilities to make separate filings for the approval of Solar-for-Schools programs and up-front rebates for distributed generation systems. This initiative will give public schools an opportunity to grow energy savings, reinvest in academic programs, and make students aware of these new technologies.
“It is my honor to serve as Commissioner during the final adoption of the Net Renewable Generation Rules,” states Central District Commissioner Brent Bailey. “These new rules will make Mississippi open to business to clean energy technology developers, manufacturers, and installers, and will help boost low-income opportunities allowing Mississippians to experience the cost-saving benefits of solar energy. It has been my pleasure to work with customers, utilities, renewable energy businesses, clean energy advocates, other stakeholders and my colleagues to improve our MPSC distributed generation policy. This policy standardizes the opportunities for individuals and businesses to invest in distributed energy resources to offset all or a portion of their overall energy use with electricity generated from on-site resources.”
“I am proud to have worked over the past 18 months to remove market barriers for consumers who want to generate their own electricity,” states Northern District Commissioner Brandon Presley. “This well-balanced rule will allow for real opportunities for the creation of good paying blue collar jobs in the solar industry. Mississippians grow their own food and fix their own vehicles and deserve to have the chance to generate their own electricity and save themselves money. This balanced, measured approach by the PSC opens the door of opportunity.”
“Also, under our Solar-for-Schools program, school districts will have the opportunity to maximize the value of their lands and see savings that can be passed on to taxpayers and hopefully lighten the onerous costs borne by parents and teachers for such things as classroom supplies,” adds Presley.
