Bill to Boost Water Production, Lower Energy Costs Passes Assembly

SB 919 will help the state avoid wasting renewable energy generation, while lowering the cost of water production

August 18, 2016

SACRAMENTO – The Assembly today passed legislation by Sen. Bob Hertzberg, D-Van Nuys, to use surplus energy to make local water recycling less expensive.

SB 919, which requires the state to better coordinate its power by directing excess renewable energy that can occur during the middle of the day toward water agencies that recycle or purify water, passed on a bipartisan 63-0 vote. The bill goes next to the Senate for concurrence.

“California’s drought has taught us we must better manage our water and do everything we can to encourage water recycling and reuse,” Hertzberg said. “It makes no sense to dump excess renewable energy or pay another state it, when we can make it available at reduced rates to those who are recycling water or making it drinkable, thereby increasing the state’s water supply.”

When the state has excess renewable energy, prices for electricity fall; this can provide an economic benefit to energy-intensive operations, like water suppliers, who can absorb that excess supply.

Specifically, SB 919 requires the Public Utilities Commission to use the excess renewable energy to develop a special economic benefit for entities that augment local water supply through recycling, desalination or brackish desalting, which is cleaning water that is too salty to drink. In addition, the bill directs the PUC to adopt other policies to reduce power oversupply.

The bill is sponsored by the Independent Energy Producers Association (IEPA) and supported by the Association of California Water Agencies, California Association of Sanitation Agencies and California Manufacturers & Technology Association. 

“California can now use its abundant solar energy to utilize new sources of much-needed water,” said Jan Smutny-Jones, chief executive officer for IEPA.

The state’s push to increase renewable energy production – SB 350 passed last year established a goal of generating half the state’s energy from renewable sources by 2030 – has created periods of oversupply that are expected to grow in coming years.

While grid operators can control when to produce man-made electricity, they can’t control when the sun shines or the wind blows, the primary sources for renewable energy. When electricity demand is lower in the spring and fall, oversupply increasingly occurs, and that forces grid operators to route the power to other states or turn off renewable energy generating facilities.

Instead, SB 919 aims to take advantage of the surplus by providing it to water producers at a lower price than they can buy it when power is in higher demand. This helps accomplish two of California’s top priorities: Encourage water recycling and avoid wasting renewable power generation.   

The process of recycling or purifying water requires substantial energy, and up to one-third the cost of the process can come from the energy bill. By letting water suppliers know when there is an oversupply of energy, regulators can take advantage of the low or negative pricing to reduce the cost of making water locally. That, in turn, will help the power grid operate more efficiently and save money for ratepayers.
