California Regional Meeting to Feature Panels on How to Meet Climate Goals

In 2016, California set a goal of reducing greenhouse gas emissions to 40 percent below 1990 levels by 2030. This is the most aggressive emissions reduction target in the United States. California Governor Gavin Newsom is directing California state agencies to accelerate the state’s progress toward its climate goals and is evaluating pathways for the state to achieve carbon neutrality by 2035.

Meeting these goals means a major shift in how electric power is generated and a greater reliance upon renewable sources, which, in turn, will lead to new kinds of investments, markets, and business practices.

One of the most promising pumped storage hydro solutions in California is the proposed 500-MW San Vicente Energy Storage Facility under consideration by a partnership of the San Diego County Water Authority and the City of San Diego.

RFP Issued for 500MW Pumped Hydro Energy Storage in California

A Request for Proposals (RFP) has been issued for a 500MW pumped hydro energy storage project at a reservoir in California by the San Diego County Water Authority.

The authority supports water supplies for more than three million people, supplying wholesale to 24 retail water providers. It has decided to put its San Vicente Reservoir into dual use by turning it into an on-demand clean energy facility while it also supplies water.

San Vicente Energy Storage Facility Powers Ahead with $18M Boost

July 16, 2021 – A large-scale renewable energy project proposed jointly by the City of San Diego and the San Diego County Water Authority received $18 million in the state budget signed this week by Gov. Gavin Newsom, enough to advance the San Vicente Energy Storage Facility through initial design, environmental reviews, and the federal licensing process.

The Energy Transition: ‘The Days When People Couldn’t Pay Attention to Their Electricity Supply are Over’

California is going through a dramatic energy transition. The state has set a goal to derive 100 percent of its electricity from carbon-free sources by 2045 and last week Gov. Gavin Newsom directed state agencies to look at moving the target up to 2035.

That means finding a way to eliminate greenhouse gas emissions from the state’s power grid while at the same time ensuring the power system remains reliable and affordable.

It’s a balancing act.

Large Energy Storage Project Would Create New Reservoir Above Isabella Lake

A $3 billion pumped-water energy storage project has been proposed along Isabella Lake that would help even out power delivery from California solar and wind farms at a volume and longevity dwarfing the large battery installations envisioned for eastern Kern.

The Federal Energy Regulatory Commission is reviewing a Walnut engineering company’s plan to create a new reservoir above the lake then use pumps and underground pipes to turn it into a rechargeable dam and hydroelectric generator putting out a whopping 2,000 megawatts of power for up to 12 hours at a time.

Opinion: California Needs to Accelerate Efforts to Achieve Clean Energy Goals

As our state has suffered through a summer of record-breaking heat waves, blackouts and wildfires, Gov. Gavin Newsom has rightly pegged what’s principally behind these challenges: “If you are in denial about climate change,” he said recently, “come to California.”

DOE Study: Solar-Hydro Projects Could Power 40% of World

Linking floating solar panels with hydropower could produce the equivalent of 40% of the world’s electricity, according to a new study by researchers at the Department of Energy.

Published this week by a team at the National Renewable Energy Laboratory, the study provides the first global look by federal researchers at the technical potential of the hybrid concept.

The research found that by constructing solar panels on the surface of hydro reservoirs and feeding the power they generate into the same substation, both energy resources might become cheaper, more efficient and more reliable.

Long-Duration Energy Storage Makes Progress but Regulation Lags Technology

If you were building an electrical grid from scratch (with no regard to regulations or finance), then long-duration energy storage would be a requisite. It just makes sense — store energy when it’s cheap and/or abundant, and discharge when the price is high, or the energy is needed by the grid. Use it to load-shift, peak-shift and smooth; to replace fossil-fuel-fired peaker plants; and to integrate intermittent renewable resources onto the grid.

Long-duration storage fits in with what utilities, independent system operators, and regional transmission operators understand. “Most utilities seem to want much longer-duration storage systems, with 6 to 12 hours discharge, to do serious load-shaping over the day,” suggests an analyst at a U.S. energy think tank. Some of these expectations are being driven by the performance of pumped hydro, once the only source of grid-connected storage.

Economically viable long-duration energy storage could accelerate solar and wind penetration, grid resiliency, and serve to stabilize volatile energy prices. But, long-duration energy storage will not become pervasive until regulators adapt to the capabilities of the technology.

Senate Energy Chair Pulls San Diego Hydropower Bill

SACRAMENTO — State Senate energy committee chair Ben Hueso said Thursday he will drop
legislation that would have boosted a hydropower project near his San Diego district.

Hueso told supporters of the project Wednesday night that he, the city of San Diego and the San
Diego County Water Authority, agreed to table CA SB597 (19R), according to an email Hueso’s
office provided to POLITICO.

Coupling Pumped Hydro With Renewables and Other Storage Technologies

The combination of pumped hydro with other storage technologies can increase renewables penetration, improve operational safety and reduce maintenance costs at large-scale hydropower plants, according to new research. The study also focuses on techniques to determine the optimal size of renewables-based pumped hydro storage systems.

Pumped hydro is highly cost competitive as a large-scale energy storage solution, according to a recent report by the San Diego County Water Authority. The higher capital costs of pumped storage technology versus battery storage are outweighed by the longer lifetime of pumped storage, which gives it a lower levelized cost, the authority said.
