Pumped Storage Hydropower is the Greenest Renewable Energy Technology, Study Says

Pumped storage hydropower is the greenest renewable energy technology for large-scale energy storage, a new study suggests.

Researchers with the National Renewable Energy Laboratory said closed-loop pumped storage hydropower will have a lower carbon footprint throughout the lifecycle of the technology, from construction to decommissioning, than other renewable energy storage technologies like lithium-ion batteries. Portland Business Journal first reported the study.

Closed-looped pumped storage hydropower uses two water reservoirs located at different elevations, one higher than the other, that generate power as water flows or gets pumped, from one reservoir to another. Closed-looped pumped storage hydropower is not connected to continuously naturally flowing water sources.

As the nation continues to push forward to reduce greenhouse gas emissions and transition from using fossil fuels to limit the effects of climate change, storing renewable energy in batteries or pumped storage hydropower has come up as a possible solution for creating cleaner energy at a large scale. Other grid-scale technologies have proven difficult to create, from gathering essential minerals to finding an area large enough to place these technologies. Researchers said closed-looped pumped storage hydropower could be the answer.

Late Addition to Energy Bill May Help Develop a Pumped Storage Facility at San Vicente Reservoir

A wide-ranging bill at the State Capitol aimed at boosting renewable energy sources includes a provision that could help develop a proposed pumped hydroelectric facility at the San Vicente Reservoir near Lakeside.

Assembly Bill 1373 aims to make the state a centralized buyer for renewable energy sources such as offshore wind power and geothermal facilities. And in a late addition to the bill, it allows the state’s Department of Water Resources to procure funding for a pumped hydro project that “does not exceed 500 megawatts and has been directly appropriated funding by the state before January 1, 2023.”

The Union-Tribune received confirmation from legislative sources that the provision specifically refers to the San Vicente project.

‘Water Batteries’ Could Power 135,000 Homes in San Diego

The San Diego County Water Authority wants to keep the lights on, even when the Sun goes down. It plans to use San Vicente Reservoir to store solar power energy in so-called water batteries to maximize the city’s renewable energy potential, NPR reports.

Cities across California have an abundance of sunny days, which is perfect for providing renewable energy… as long as the Sun is up. The proposed project could store 4,000 megawatt-hours of energy per day, which could power 135,000 homes after the Sun goes down. To make this possible, the San Diego Water Authority would create a smaller upper reservoir just above the existing San Vicente Reservoir. These would be connected by a tunnel system and an underground powerhouse.

‘Water Batteries’ Could Store Solar and Wind Power for When It’s Needed

The San Diego County Water Authority has an unusual plan to use the city’s scenic San Vicente Reservoir to store solar power so it’s available after sunset. The project, and others like it, could help unlock America’s clean energy future.

Tiny Oregon Town Hosts 1st Wind-Solar-Battery ‘Hybrid’ Plant

A renewable energy plant being commissioned in Oregon on Wednesday that combines solar power, wind power and massive batteries to store the energy generated there is the first utility-scale plant of its kind in North America.

The project, which will generate enough electricity to power a small city at maximum output, addresses a key challenge facing the utility industry as the U.S. transitions away from fossil fuels and increasingly turns to solar and wind farms for power. Wind and solar are clean sources of power, but utilities have been forced to fill in gaps when the wind isn’t blowing and the sun isn’t shining with fossil fuels like coal or natural gas.

Energy Shift Creates Opening for ‘World’s Largest Batteries’

Sprawled like a gigantic swimming pool atop a bluff overlooking Lake Michigan is an asphalt-and-clay pond holding enough water to produce electricity for 1.6 million households.

It’s part of the Ludington Pumped Storage Plant, which uses simple technology: Water is piped from a lower reservoir — the lake, in this case — to an upper one, then released downhill through supersized turbines.

Supporters call these systems “the world’s largest batteries” because they hold vast amounts of potential energy for use when needed for the power grid.

The hydropower industry considers pumped storage the best answer to a question hovering over the transition from fossil fuels to renewable energy to address climate change: where to get power when the sun isn’t shining or the wind isn’t blowing.

San Diego Looks for Partner to Build $1.5B San Vicente Hydro Energy Project

The project is on the drawing board. Now the San Diego County Water Authority and the city of San Diego are looking for a private partner to build and operate a pumped energy storage facility at the San Vicente Reservoir.

The Water Authority and the city have issued a request for proposal to find a suitable team to develop one of the state’s largest “pumped hydro” projects that would add megawattage and flexibility to California’s electric grid. Proposals from potential partners will remain open until Nov. 3.

Water Authority Seeks Proposals for Pumped Storage System at San Vicente

The San Diego County Water Authority has issued a formal request for proposals to build a pumped-storage generating system at the San Vicente Reservoir by 2030.

The project would use excess solar and wind energy to pump water to a new reservoir above the current dam, and then release it through turbines to generate up to 500 megawatts of electricity when needed.

Request for Proposals Issued to Develop San Vicente Energy Storage Facility

San Diego County Water Authority this week issued a formal Request for Proposals seeking a full-service private partner capable of developing a large-scale pumped energy storage project planned jointly by the Water Authority and the City of San Diego. Proposals are due by 2 p.m. Nov. 3. The partner agencies aim to maximize the value of the existing San Vicente Reservoir for on-demand energy generation to support the state’s clean energy goals.
