LG&E-KU Requests Changes to the Solar Net Metering PolicyLouisville Gas & Electric and Kentucky Utilities are requesting a slight increase in the solar net metering compensation rate but it still isn't enough and it maintains the "instantaneous netting" policy which undermines the value of rooftop solar and is unfair to solar customers.
Case #2023-00404Value of Solar
Rooftop solar brings many benefits to both electric utilities and solar customers. As such it is important that the value of solar reflects the full range of benefits. While LG&E-KU are proposing a slight increase in the solar net metering compensation rate it is still much lower than the retail rate (the price at which you purchase electricity from the grid). The Public Service Commission should ensure that LG&E-KU account for avoided cost of carbon pollution and the economic development benefits of roof top solar. Monthly Billing vs Instantaneous Billing In the last Net Metering case before the Public Service Commission LG&E-KU transitioned from a "monthly" billing policy to an "instantaneous" or "two channel" billing. In this current case they are proposing to continue with the "instantaneous" billing policy which is an unfair policy to customers that undervalues rooftop solar. “Instantaneous” or “two channel billing” greatly reduces the value of electricity generated from rooftop solar by crediting each kWh generated that is not immediately used in real-time at the “avoided cost” rate instead of letting the customer “settle-up” at the end of the month. This not only reduces the value of rooftop solar and makes it less economical for people to install rooftop solar, but it also has a huge impact on the rooftop solar industry as well. Two channel billing is much harder to explain to people and to calculate return-on-investment. It makes it more difficult for installers to correctly size an installation to achieve greatest financial return or to fully offset a customer’s annual electric energy cost. For example, under two channel billing with low compensation value, a solar array installed on a working class family home, where the occupants are away from home much of the daylight hours and use more electricity at night, can have a substantially lower savings than the same solar array installed on a retired couple’s home that is occupied much of the daylight hours, and thus tends to use more electricity during the daytime. Additionally, under two channel billing with low compensation value, a customer is incentivized to keep their solar system size much smaller than would be needed to meet their annual electricity use, since to do otherwise (install a system large enough to make the building net zero) would likely result in a much larger percentage of generation being compensated at reduced value. |

Sample Solar Net Metering Talking Points
Rooftop solar is valuable. It benefits customers AND the utilities. That means that the utilities need to credit us for the full value to the energy system including all avoided costs and economic development benefits.
Rooftop solar helps customers to take control over their electric generation and to lower their power bills. Rooftop solar also lowers “peak demand” for utility companies which is the time during the day that it is most expensive for them to generate electricity, that means lower costs for the utility company and for us.
Our electric bill comes once a month, solar accounting should use the same time frame.
It is fair, just and reasonable to use a monthly “netting” process to account for the amount of electricity we are charged and credited for on a monthly basis. This process is easy and straightforward for customers, solar installers and utility companies and their billing software. It recognizes the full benefit to the customer-generator of the amount of electricity generated throughout the billing period and it is in line with the state statute that empowers the PSC to set net metering compensation rates. Using anything besides a monthly netting accounting method will harm solar customers and only serves the utility company in undermining rooftop solar.
Rooftop solar is an important utility resource that helps us meet our current and future electricity needs and climate commitments.
Utilities should do everything they can to encourage rooftop solar through continuing to offer strong net metering programs indefinitely.
Net metering of rooftop solar is a very low cost resource for utilities and their customers.
At a time of increasing demand and concerns about grid reliability and the transmission system, customers who are willing to invest their own capital into solar generators on their own properties should be encouraged to do so.

What is Net Metering?
Net Metering is a way to compensate rooftop solar users for the extra electricity they put onto the grid. When the sun is shining you may produce more energy than you need for your home. "Net metering" keeps track of the extra electricity that you put onto the grid (that the energy company can redistribute to your neighbors for free) and gives you credit towards pulling electricity off the grid when your panels aren't producing. We used to have a 1:1 net metering compensation rate, meaning for every extra KW/hr you put onto the grid you could pull an equal amount off the grid at a later time. Electric utilities lobbied to change that compensation rate and now each utility has different ways of crediting you for your extra rooftop solar. |
