Cal Lawmakers Propose Smaller Increase for Net Metering

A state Senate committee voted to set the cap at 3.5 percent instead of the 5 percent in an earlier version of the bill, which sets out to expand a program that has largely benefited solar energy system owners.

California lawmakers have proposed to raise the net metering cap to 3.5 percent, a move that is sure to upset solar energy advocates.

The Senate Appropriations Committee voted for the 3.5 percent cap after getting the bill from the Senate's Energy, Utilities & Communications Committee, which voted to raise the cap to 5 percent.

The net metering program has been running for years. The latest proposed cap would only be a slight increase from the existing cap of 2.5 percent.

The Appropriations Committee didn't want to raise the cap too much until state lawmakers have a better understanding of the costs of net metering to ratepayers and the state, said Brendan McCarthy, principal consultant for the committee, on Tuesday.

The California Public Utilities Commission (PUC) is set to release a report in January examining the cost issues, including whether the program is unfairly subsidizing a small group of ratepayers, McCarthy said.

"None of the utilities are near their cap now, and we feel the 3.5 percent is appropriate until the CPUC report," McCarthy said.

The net metering program allows customers of all utilities (except the Los Angeles Department of Water and Power) to get credits on their bills for producing more renewable electricity than what they could use at home or business. The excess electricity, from sources such as solar or wind, goes to the grid.

The program presents an enticing incentive for consumers looking at installing solar energy systems on their rooftops. Systems at or under 1 megawatt in capacity can qualify for net metering. The program currently has a 2.5 percent cap. That means each utility would stop accepting new participants in the program once the overall generation capacity of its net metering customers' systems reaches 2.5 percent of the load (aggregate customer peak demand). 

The program has become so popular in Northern California that the Pacific Gas and Electric Co. could hit that upper limit as soon as this year, according to an analysis by McCarthy (another state legislative staff report said PG&E could hit the limit in 2010). As a result, lawmakers began to consider raising the cap.

The state Assembly took the first crack at the bill, AB560, and eventually voted in May to increase the cap to 10 percent.  

Utilities opposed the 10 percent proposal, calling the limit too high and would cost too much for customers, particularly those who couldn't afford or simply don't want solar panels. The utilities run the net metering program and recoup costs through rate increases, which have to be approved by the PUC.

There are concerns that net metering customers aren't paying their fair share of the fees for operating and maintaining the transmission and distribution systems, or for programs that support energy efficiency efforts and low-income utility customers, McCarthy said.

By earning and banking credits, net-metering customers who generate more than they could use consistently wouldn't need to pay their utilities for electricity, even though they do need to rely on electricity procured and provided by their utilities at night, when the solar panels aren't generating power.

Utilities calculate some of the fees based on the electricity they sell. So a net metering customer who doesn't owe the utility for electricity would not have to pay some of the fees.

Other utilities have looked at similar issues. Xcel Energy in Colorado was hoping to recoup the fees for maintaining the grid by imposing a charge on its net metering customers. But it withdrew the plan, which was submitted to state regulators for approval, after facing strong protests last month.

San Diego Gas & Electric has opposed the 10 percent or the subsequent 5 percent proposal for the net metering cap. The utility supports solar installations, but would like state lawmakers to wait for the PUC report before deciding to raise the cap significantly higher, said Jennifer Ramp, a spokeswoman for SDG&E.

SDG&E has reached just over 1 percent with its net metering program, Ramp said.

"The cap is there to protect our customers from unreasonable rate increases," Ramp said. "We are concerned about non-solar customers who might be burdened with unreasonable costs."

But solar energy advocacy groups such as the Vote Solar Initiative in San Francisco said the 3.5 percent proposal is way too low.

"The move puts stimulus projects, green jobs, the growing solar market and energy bill savings for anyone who wants to go solar at risk," wrote Rosalind Jackson, a spokeswoman for Vote Solar, via email.

The full Senate could vote on the net metering bill as early as this week, McCarthy said. After that, the bill would go to the Assembly for consideration, since the Assembly had voted on a different cap. The governor has until Oct. 11 to sign the bill for it to take effect in January.

    I wrote a call to action to the industry about this on my Renewable Energy World Blog:

    http://www.renewableenergyworld.com/rea/blog/post/2009/09/solar-people-we-have-a-big-problem-you-and-your-staff-are-the-solution-

    What isn’t stated here is that the excess energy that is produced during peak times during the day, the utilities don’t just throw that away. Others (nearby neighbors) use that electricity, which in theory means that the utility doesn’t have to produce that power from dirty coal. Without net metering, utilities are profiting from that excess.

    Now, if you want a feed-in-tariff alternative, fine, but make it worthwhile, Personally, I think net metering works and is sustainable, but ...not I’m not a solar economist, so I’ll wait for that Public Utilities report, which I hope will be objective and unswayed by lobbyists. Then we’ll go from there. I the meantime, I don’t see why 5% for now would be so bad.

    Thank you for this excellent report, Ucilla.

        With PG&E Net Metering, the rates are time-of-day and season sensitive—in summer it’s $.29/kWh weekday afternoons, and .08 off-peak. Really conserving home electric use during these hours could make a big difference in payback, since you could sell high and buy low.

        But without PV panels during the day, PG&E runs inefficient peaker gas turbines (not coal or efficient combined cycle units since these need constant use).  According to the CA Energy Commission, this peaker plant electricity costs $.32-35/kWh (transmission excluded) because they aren’t used all the time, so utilities still have some leeway. Also, locally distributed generation offsets some of the long distance transmission requirement. Fortunately, peak demand occurs when PV panels are working best (demand is less on cloudy days).

        [Utilities take a loss during peak demand, but make up for that on off-peak baseline use—prices are regulated so the utilities are viable companies. So even though the power companies pay retail prices for home solar to resell, cutting peak demand can still be profitable because they are operating at a loss anyway at this time. Because most people a pay flat rate, we could in theory lower energy cost with time-of-day metering and smart appliances with use changes to shift usage away from peak times.]

        In other countries like Germany, the feed in tarriff is high, e.g. EU$.50/kWh and people sell all output of panels at that rate, then buy the power back and half or less the price for home use. The Net-Metering system in CA means you can only sell the difference, and the amount you can sell can’t exceed what you have to buy over the course of a year.

        Ah thanks, Solar Fred. Good point about the excess electricity that is available for the utility to manage and use.

    My wife and I installed a 6.12kw PV system in June of 2006 with a Time of Use (TOU) E-7 net meter with PG&E.  We have sent back 5000 kws to the grid at peak times over the last three years.  The $.29 a kw credit we get for each kw we send back to the grid was used in our calculation to determine our payback period.  The higher the feed in tarrif the faster our payback. 

    The folks, resiential and commercial users,  who went with PV net metering are no longer supporting the public purpose programs (18% of my last true up bill) or the 9% to cover the DWR bonds at the dollar amounts they used to.  As the percentage of folks who go with a net meter increased the total dollars lost for public service programs goes is going up (and the need is going up).  Rate payers who are paying a marginal rate of .37 to .44 a kw are getting a bit annoyed at having to cover the majority of the public service programs.  I know I was annoyed at having to pay the very high marginal rate for a kw of electricity.

    My net-metering billings from PG&E (as reflected in the full bill) includes a fixed daily fee for at least some of the public service programs, so even in those months where we have generated more power than we have used, we have a positive charge for electricity. In spite of reading the rate chart carefully, I am still not sure what will happen at true-up time, but I think we will have a net positive fee regardless of how much we generate.
