The Rapid Maturation Of The U.S. Energy Storage Market

/in , /by /PV Magazineby Amish Shah, Madeleine Tan, Kyle Hayes and Alyssa Walker

The U.S. energy storage market is primed to grow at a rapid pace. A study by IHS Markit forecasts that the U.S. grid-tied energy storage market will nearly double in 2019 – from 367 MW in 2018 to 712 MW this year – which does not include behind-the-meter energy storage that would add several hundred MW of deployed energy storage to the forecast for 2019. This significant expansion is poised to occur against a backdrop of regulatory changes in federal and state incentive programs, cost improvements and advances in monetization of energy storage. These current and anticipated trends affecting the U.S. energy storage market will have a significant influence on how industry participants choose when, where and how to invest in and develop energy storage technology.

As the sun sets on California’s solar farms, a backup energy source deep in the Sierra Nevada Mountains springs to life. The huge system of reservoirs and turbines can store energy during the day and then crank out electricity for 900,000 homes, using just water and gravity.

As the state tries to make wind and solar work around the clock, officials want to build more like it. It won’t be easy: such projects take years to develop, are expensive and face stiff opposition.he push by California and other states to revive the century-old technology — called “pumped-hydro storage” — underscores the limitations of modern batteries.

Water Authority Supports Bill to Spur Pumped Storage Projects

/in , /by

A bill that the San Diego County Water Authority’s Board of Directors voted to support in March is scheduled for a hearing Thursday in the state Senate Appropriations Committee. The proposed state legislation promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

Senate Bill 772 by Sen. Steven Bradford of Gardena promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

The Board’s support for the legislation followed the March release of a research paper from a team led by UC San Diego Professor David G. Victor that emphasizes the benefits of expanding pumped hydro energy storage as a cost-effective way to help California meet its renewable energy goals and reduce greenhouse gas emissions.

Read the Pumped Energy Storage report here.

The Water Authority and the City of San Diego are exploring a potential pumped storage energy project at the San Vicente Reservoir that could store 4,000 megawatt-hours per day of energy, or 500 megawatts of capacity for eight hours.

Energy generated by renewable sources, like wind and solar, can be captured by energy storage facilities and then distributed then needed. Batteries and pumped energy storage will provide the needed energy storage for both short-term needs (batteries, less than 4 hours) and long-duration needs (pumped energy storage, 8 hours or more).

Large-scale, long-duration renewable energy source

A key to the San Vicente concept and others is development of statewide institutional and regulatory support for large-scale, long duration energy storage lasting up to eight hours. Pumped storage projects store solar and wind power during low-demand periods for use during high-demand periods, such as evenings when people are cooking, washing clothes and running air conditioners.

The State Energy Resources Conservation and Development Commission has identified bulk energy storage – including pumped hydroelectric storage – as a core strategy for integrating renewable energy resources into the California electrical grid and reducing greenhouse gases.

In addition, the white paper stresses the need for new state policies that will ensure that pumped energy storage projects enter commercial operations when they will be critically needed.

“To be consistent with California’s energy vision, active new policy support is needed to facilitate the development of pumped energy storage,” according to Victor’s paper. “Those policies should recognize the long lead times in building pumped energy storage projects (5 to 10 years). New policy efforts must begin now.

“Among the needed actions are state-backed support for some early projects that would jump start investment in this proven technology. This support can demonstrate viable business models and investment strategies that will pave the way for more private sector-led projects in the future.”

Providing ratepayer benefits

Pumped energy storage projects work like giant batteries by storing excess renewable energy during the day, when renewable power production peaks. Energy is released from the “battery” in the evening, when energy use increases, and renewable energy is not available.

Keeping the electrical grid reliable requires not only short-term energy storage, but long-duration, large-scale storage.

“Many expert studies have been performed that demonstrate the value of pumped energy storage, including CAISO’s Bulk Energy Storage Case Study, which found that a 500 megawatts (MW) pumped energy storage project in Southern California would provide ratepayers with a savings of up to $51M per year from improved efficiencies in system operation,” according to Victor’s white paper.

“Without significant new large-scale energy storage, California will likely be required to import more energy from other states, including potentially power generated with higher carbon emissions, such as coal,” the paper said. “The State will be unable to meet its renewable and climate goals reliably without large-scale energy storage.”

SB 772 is an attempt to address some of the issues identified by Victor and others. The legislation would require the California Independent System Operator, which runs the state’s power grid, to create a competitive bidding process by June 2022 to acquire a substantial quantity of long-duration energy storage – the type created by pumped hydroelectric storage.

How LADWP Uses Two Lakes To Store Energy Like A Giant Battery

If L.A. is going to stop burning fossil fuels by 2045 a key goal of Mayor Eric Garcetti’s proposed Green New Deal it must store a lot more of the excess solar and wind energy it produces during the day so it doesn’t have to rely on gas and coal energy to power the city when the sun sets and the wind dies. There’s a growing focus on building big batteries — for example, the kind that use lithium ions. But L.A. needs energy storage that is far bigger than any traditional battery.

San Diego County Students Shape the Future of Water

/in , /by

On April 25, the San Diego County Water Authority Board of Directors honored the latest group of water-related award winners from the Greater San Diego Science and Engineering Fair as part of the agency’s effort to inspire young people to pursue water industry careers.

This year’s middle school and high school science and engineering projects displayed a wide range of innovative ways to solve a variety of water issues people face today.

In the senior division, Alfred and Audrey Vargas won the first place award with the design of a new device to treat wastewater and generate electricity simultaneously using hydrogen fuel cell technology. The siblings, who attend Sweetwater High School, also won their division last year and continue their work in designing devices and systems that can potentially be used in developing countries where resources are scarce.

Alfred and Audrey have been competing in science fairs since they were in middle school and have always been inspired by a drive to solve world water issues in affordable ways.

“As we’re looking for the next generation of water industry professionals, events like the Greater San Diego Science and Engineering Fair are the perfect opportunity to connect with and support students who are already interested in relevant water issues,” said Water Authority principal public affairs representative Risa Baron, who helped select the winners. “These young thinkers and inventors can make huge strides in solving future water challenges around the world.”

Finding inspiration in the natural world

Cambridge School student Emily Tianshi won the second place award in the senior division. She looked beyond the ocean views at Torrey Pines State Park to see the intelligent ways that nature sustains itself and how those can be imitated.

Emily spent the past three years perfecting a design for a device that can capture moisture from the air like Torrey Pine needles do. Using 3-D printing technology to bring her project to life, Emily demonstrated that the naturally occurring ridges of Torrey Pine needles efficiently collect water, and she designed a model of a device that would mimic the shape of the needles.

In the junior division, Brendan Cordaro and Max Shaffer from Saint John School in Encinitas teamed up to win first place with “The Water Maker,” a homemade device that transformed a miniature refrigerator into a means of collecting water from the air.

Oliver Trojanowski, who is also a middle school student at the Saint John School, won the second place award in the junior division. Oliver surveyed several sites in the region to test for water quality and determine toxicity levels in stormwater runoff.

Matthew Angulo from the Corfman School in El Centro earned the third place award in the junior division. He travelled over 100 miles to showcase his results from several tests of water samples from the Colorado River.

Welcoming the next generation of water professionals and leaders

More than 2,800 people across all levels of educational attainment work at the Water Authority and its 24 member agencies to provide safe and reliable water supplies to the region.

The Water Authority and its member agencies are committed to fostering the next generation of industry professionals and leaders. Engineers, system operators, maintenance technicians, customer service representatives and utility workers are just some of the many careers available in the water industry.

Electricity Costs From Battery Storage Down 76% Since 2012: BNEF

/in , /by /The Utility Dive (Washington D.C.)by HJ Mai

The ever-decreasing cost of electricity from batteries is giving fossil fuels a run for their money as renewable energy projects combined with battery storage become increasingly competitive power supply options. The LCOE for lithium-ion batteries has fallen 35% to $187/MWh since the first half of 2018, research company BNEF said Tuesday. Going back to 2012, BNEF found the cost of battery storage has dropped 76%, from almost $800/MWh.

Cities, County Looking To Team Up On Public Alternative To SDG&E

/in , /by /The San Diego Union-Tribuneby Joshua Emerson Smith Mentioned: San Diego County Water Authority

Elected officials throughout the San Diego region are ramping up efforts to form a public alternative to San Diego Gas & Electric, with the city of San Diego leading the way and even the county Board of Supervisors now looking at signing up. California’s three large investor-owned utilities have since 2010 seen more than 8 million customers defect to so-called community choice aggregation programs, from Humboldt to Los Angeles to Solana Beach. However, SDG&E is now facing the largest displacement of a utility’s customer base in the state — raising question about everything from grid reliability to whether the public alternative can deliver more renewable energy as promised.

Top State Utility Regulator Intervened in Cost Study for Expanded Energy Grid, Records Show

/in , /by /The San Diego Union-Tribuneby Jeff McDonald

One of the most pressing questions about a plan to expand the California power grid to as many as 14 states was how much it would cost to transfer oversight of the poles and wires from a state-run nonprofit to a regional board of appointees. The California Public Utilities Commission told lawmakers the plan to redefine the way electricity is regulated would cost the agency $700,000. But according to internal documents obtained by The San Diego Union-Tribune, the price tag for the so-called regional power grid was $2.4 million when it was developed by rank-and-file analysts. Utilities commission President Michael Picker rejected that finding as too high.
