Net Metering and Valuing Rooftop Solar

Net Metering and Valuing Rooftop Solar

Because Rocky Mountain Power is a monopoly, it has to request permission from the Utah Public Service Commission if it wants to change its prices (aka electricity rates). Utah Clean Energy wants your electricity rates to reflect good policy—that is, we want to see price signals (for all you economics geeks out there) that encourage smart energy behaviors, like energy efficiency, electric plug-in vehicles, and rooftop solar.

The Latest
You likely remember all the hubbub last summer when Rocky Mountain Power requested a new fee for rooftop solar customers, arguing that solar customers aren't paying their fair share to connect to the grid. Utah Clean Energy and hundreds of others pushed back on this premise and won the day when the Utah Public Service Commission denied the fee pending an analysis of the costs and benefits of rooftop solar. As the saying goes, be careful what you wish for! Over the course of the next several months, Utah Clean Energy and other experts will be filing testimony, and the docket will culminate with a hearing in October, including a public witness hearing where you can make your voice heard.  Stay tuned!

Several Municipalities Modifying Their Net Metering Policies
Several municipal utilities are making changes to their net metering programs.  Santa Clara has replaced their net metering program with a  feed-in-tariffKaysville has issued a temporary moratorium on net meters to review their net metering program which may take up to 6 months, but will likely be finished more quickly. South Utah Valley Electric Service District (SESD) has also issued a moratorium. A spokesperson from SESD says they hope to have a plan in place that will lift the moratorium by the end of the year. For more information on changes to these net metering programs, email Utah Clean Energy's Solar Program Coordinator Kate Bowman.

Net Metering Working Groups
The analysis begins with a series of working groups to delve into the challenges, solutions and opportunities that come with integrating rooftop solar into our energy system. It’s technical, it’s complex, and oh so important for the future of solar energy in Utah! This is the stage in which we can safeguard Utah's burgeoning solar industry from future attacks and pave the way for countless more Utah families and businesses to go solar. As of July, we have had four working group meetings to discuss issues related to net metering. And as your advocates for clean energy, Utah Clean Energy will be heavily involved in the remainder of the process. For the energy nerds reading this, below is an update on the more technical aspects of the working groups.

Fourth Working Group (July 8)

You may not scrutinize your electricity bill, but if you did you would discover that there are many different components to it: energy charges, customer charges, minimum bills, seasonal and time of use pricing, and for commercial customers, a demand charge or a facilities charge.  Simple, right?  When electricity bills are structured well, they incent good behaviors (like conservation) and discourage electricity usage that is wasteful or costly. When the cost-benefit analysis is completed, the findings of the analysis will need to be converted into electricity prices (“rates”).  A good electricity rate will provide adequate compensation for solar energy, protect low-income customers, reward smart energy choices, and also be simple and understandable to the average human. There are many ways to design rates for net metering customers, and it's important that we get it right.

Third Working Group (June 25)

This working group focused on existing cost tests, which are used to evaluate energy efficiency programs and whether (and how) these tests could be used to evaluate net metering. The DSM (or "Demand Side Management"—a fancy way of saying energy efficiency) tests tell us whether a given energy efficiency initiative - like incentives for more efficient lightbulbs - is a good deal from the perspective of the utility and its customers. These tests can tell us whether a program is a good investment, but when the time comes to recover the costs from customers, regulators must do so by establishing prices in a process called “ratemaking.” More of an art than a science, ratemaking requires utilities and regulators to balance many different, sometimes competing goals (for example, providing low-cost, reliable service; mitigating long-term risk; and ensuring access to electricity to low-income Utahns).

Second Working Group (May 12)
The topics of the second workgroup were (1) cost-benefit analyses and (2) how NEM is evaluated and valued through existing utility planning analyses, including IRP and Cost of Service studies.  Dr. Thomas Vitolo with Synapse provided an overview of cost and benefit categories that can be considered in a net metering cost-benefit analysis.  Jason Keyes with IREC outlined the key differences between a cost-benefit analysis and a cost of service study and highlighted best practices for both.  A cost of service study is designed to determine the cost of providing electricity service to a particular class of customers to help determine prices for each type of customer based on how they use energy.  A cost-benefit analysis takes a broader look at the costs and benefits of net metering, including benefits like avoiding delivery line losses, providing grid support, and avoiding or deferring transmission and distribution investments.

First Working Group  - Who Can Talk Utility Distribution for 7 Hours?
We can!  The first working group kicked off by focusing on challenges and opportunities related to solar and the utility’s distribution system (how electricity gets from the transmission system to your house). Essentially, we discussed how rooftop solar is different from other sources of power, how the utility gets power from source to customer, and what impacts increased rooftop solar will have on this process.  For our contribution, Utah Clean Energy brought in two technical experts to give presentations on lessons learned by areas like Hawaii and California, who are seizing their rooftop solar potential while successfully managing its impacts on utility transmission and distribution.  Our expert from Clean Power Research showed how rooftop solar can actually help a utility avoid transmission and distribution costs as it provides energy on-site. It may not sound like a page-turner to you, but it was a thought-provoking presentation that outlined a win-win pathway for increased solar in Utah.

Background

The debate over Rocky Mountain Powers' highly controversial 2014 proposal for a $4.65 solar fee included 6 rounds of testimony, countless meetings and thousands of community advocates.  If you are interested, you can check out all of the related testimony and documents here including the testimony of Sarah Wright and Rick Gilliam on behalf of Utah Clean Energy.

In July of 2014, Utah Clean Energy submitted the last round of testimony followed by two days Public Service Commission hearing: cross examining witnesses and undergoing cross-examination regarding our testimony advocating for a fair shake for rooftop solar. 

The public hearing followed and we were thrilled with the amazing turnout! Approximately 60+ citizens participated in the public hearing, voicing opposition to the proposed solar fee. These participants included Utahns with and without solar, retirees, doctors, parents, businesses and concerned citizens of all ages.
