Proposal to Place Solar Panels Over LA Aqueduct Advances

A proposal to place solar panels over the 370-mile Los Angeles Aqueduct in an attempt to reduce evaporation and add capacity for renewable energy for residents was approved by a council committee this week. Around one-tenth of the water in the aqueduct is lost from evaporation each year due to the length of travel for water to make it through the aqueduct, according to the office of Councilman Mitch O’Farrell, who introduced the motion. O’Farrell is the chair of the council’s Energy, Climate Change, Environmental Justice, and River committee.

San Diego County Aims to Provide More Homes with Power by Storing Energy in reservoir

San Diego County aims to provide more homes with power by storing energy in reservoir

 

 

The West’s Biggest Source of Renewable Energy Depends on Water. Will it Survive the Drought?

Reports of low water levels at a few big hydropower plants in the West over the last few years have made it seem like hydropower is becoming less reliable. Last summer, officials in California were forced to shut down the Edward Hyatt Powerplant when water levels in Lake Oroville, the reservoir that feeds the plant, dropped below the intake pipes that send water into its turbines.

‘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.

Opinion: ‘All Hands on Deck’ for the Energy Storage Industry

Energy storage technology may be the singular, most important component in our nation’s transition away from fossil fuels to renewable energy, since utility-scale, battery systems provide the flexibility to absorb, store and deploy energy at locations where and when the power is most needed. Energy storage is crucial to replacing America’s fleet of polluting, fossil fuel plants because they integrate the increasing amounts of wind, solar and hydropower being transmitted hundreds of miles without jeopardizing grid reliability — sometimes the wind isn’t blowing or the sun isn’t shining where and when the power is most needed.

UN Floats Plan to Boost Renewables as Climate Worries Mount

The United Nations chief on Wednesday launched a five-point plan to jump-start broader use of renewable energies, hoping to revive world attention on climate change as the U.N.’s weather agency said greenhouse gas concentrations, ocean heat, sea-level rise, and ocean acidification reached record highs last year.

“We must end fossil fuel pollution and accelerate the renewable energy transition before we incinerate our only home,” U.N. Secretary-General Antonio Guterres said. “Time is running out.”

California Governor Floats 5-GW, $5.2B ‘Reliability Reserve’ Amid Possible Electricity Shortfalls

California Gov. Gavin Newsom, D, has earmarked $5.2 billion in a revised budget proposal released Friday to fund a “strategic electricity reliability reserve” – an up to 5,000 MW resource that the state can tap into when the grid is particularly stressed.

Stable Renewable Energy Prices Locked In by Helix Water District

Proactive efforts by the Helix Water District have saved thousands of dollars per year in the district’s energy costs, and are helping it transition to renewable energy.

Stable Renewable Energy Prices Locked In by Helix Water District

Proactive efforts by the Helix Water District have saved thousands of dollars per year in the district’s energy costs, and are helping it transition to renewable energy.

Helix buys most of its electricity through the State of California’s Direct Access Program and the electric service provider it contracts with, Calpine Energy Solutions. Helix has worked with Calpine since 2007 to manage the district’s energy costs and its move to renewable resources. It recently renewed its electricity-purchasing contract with the San Diego-based company that sells electricity. Helix relies on utilities like SDG&E, Southern California Edison, and PG&E to deliver it.

Helix negotiates contracts with Calpine that allow the district to lock in the price it pays for electricity. This limits the district’s exposure to events that cause energy costs to increase, like reduced hydropower production due to the drought, and higher natural gas prices due to the war in Ukraine.

Helix customers protected from market price increases

Calpine has also secured the renewable energy supply Helix needs through 2030. Calpine sources renewable energy from a portfolio of developers, including a new solar power facility in Riverside County. This will protect Helix and its customers over the next eight years, as market prices respond to increased demand and competition for renewable energy.

“For the last several years we’ve seen double-digit savings as high as 18% on electricity,” said Helix Assistant General Manager Brian Olney. “This year, with all that’s going on in the world and the market, we are doing very well for our customers.”

“We want stable prices for electricity because that helps stabilize water rates for our customers,” said Helix Board President Kathleen Coates Hedberg. “And we want the district to do its part to meet statewide goals for the use of electricity from renewable resources.”

Energy efficiency helps reduce costs

Helix also reduces costs by improving energy efficiency. In 2011, the district installed solar panels on its operations center in El Cajon that generate 90-100% of the facility’s electricity. In 2012, they retained DHK Engineers to perform an energy audit of all of the district’s facilities and operations.

“Implementing the recommendations from the audit reduced our annual energy use by 11%,” Olney said.

The next step at Helix is transitioning into electric vehicles. The district began the transition in 2019, with a grant from SDG&E to install electric vehicle charging stations, and rebates from the State of California on six Toyota Prius.

“This year,” said Helix Operations Director Kevin Miller, “we are testing Ford’s new electric pickups. We like to see companies move in this direction because when they take a step forward, Helix Water District takes a step forward.”
