Long-Duration Energy Storage Makes Progress but Regulation Lags Technology

/in , , /by /pv magazineby Eric Wesoff

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.

California’s Dams Need Repairs to Survive Future Major Flood, says Author

/in , , /by /Press Play (KCRW-FM)

A recent UCLA study says that in the next 40 years, California could likely see a flood massive enough to cause nearly $1 trillion of damage, force millions of people to evacuate, and leave houses in California’s Central Valley 30 to 40 feet underwater. And the state is ill-prepared when it comes to infrastructure like dams that could prevent flooding.

Opinion: California Must Prepare its Electric Grid for Complex Climate Risks

/in , , /by /San Francisco Chronicleby Anna Brockway, Laurel Dunn and Steven Weissman

California was caught flat-footed by the climate-driven challenges it has faced last week: extreme temperatures, unseasonable lightning strikes, diminishing water supplies and red flag fire conditions. As a result, CalFire was short on firefighters to battle the blazes and the electric utilities had too little power to serve all of their customers at the same time.

San Diego ocean temperatures hit record territory this past weekend, as a heatwave also baked the San Diego Region. The record comes just weeks after the unseasonably cool ocean temperatures were recorded. Someone has taken the temperature at the end of Scripps Pier every day for more than 100 years. Sunday’s reading tied for the hottest on record 79.5 degrees Fahrenheit. It tied the record that was set just two years ago.

Major Real Estate Website Now Shows Flood Risk. Should They All?

/in , /by /NPRby Rebecca Hersher and Lauren Sommer

Millions of people rely on real estate websites when they’re hoping to buy or rent a home. Major sites such as Zillow, Redfin, Trulia and Realtor.com feature kitchens, bathrooms, mortgage estimates and even school ratings. But those sites don’t show buyers whether the house is likely to flood while they’re living there. Now, Realtor.com has become the first site to disclose information about a home’s flood risk and how climate change could increase that risk in the coming decades, potentially signaling a major shift in consumers’ access to information about climate threats.

Why Renewables Aren’t to Blame for California’s Blackouts

When blackouts rolled across California on August 14 and 15, briefly cutting off power to several hundred thousand households and their air conditioners, fridges, and medical devices during a pandemic and a record-breaking heat wave, some critics blamed the state’s heavy reliance on solar and wind energy. As the state pursues its ambitious renewable energy goals, they asked, will electric power become unreliable?

The San Diego County Water Authority announced Monday it is partnering with the Scripps Institution of Oceanography at UC San Diego to better predict atmospheric rivers and improve water management before, during and after those seasonal storms. This month, Scripps’ Center for Western Weather and Water Extremes launched the Water Affiliates Group, which brings together science and hands-on water industry experience to enhance reservoir operations in light of the changing climate. The water authority has a long-running alliance with Scripps.
