Oncor proposes giant leap for grid batteries Dallas Morning News
Oncor, which runs Texas’ largest power line network, is willing to bet battery technology is ready for wide-scale deployment across the grid.
In a move that stands to radically shift the dynamics of the industry, Oncor is set to announce Monday that it is prepared to invest more than $2 billion to store electricity in thousands of batteries across North and West Texas beginning in 2018.
Utility-scale batteries have been a holy grail within the energy sector for years. With enough storage space, surplus electricity can be generated at night, when plants usually sit idle, to be used the next day, when demand is highest. Power outages would become less frequent. Wind and solar power, susceptible to weather conditions, could be built on a larger scale. The only problem has been that the price of batteries has been too high to make economic sense. But if they’re purchased on a large enough scale, that won’t be the case for long, said Oncor CEO Bob Shapard.
“Everyone assumed the price point was five to six years out. We’re getting indications from everyone we’ve talked to they can get us to that price by 2018,” he said in an interview Wednesday.
The Dallas-based transmission company is proposing the installation of 5,000 megawatts of batteries not just in its service area but across Texas’ entire grid. That is the equivalent of four nuclear power plants on a grid with a capacity of about 81,000 megawatts.
Ranging from refrigerator- to dumpster-size, the batteries would be installed behind shopping centers and in neighborhoods. Statewide, Oncor estimates a total price tag of $5.2 billion. A study commissioned by Oncor with the Brattle Group, a Massachusetts consulting firm that provides power market analysis for state regulators, says the project would not raise bills. Revenue from rental of storage space on the batteries, along with a decrease in power prices and transmission costs, should actually decrease the average Texas residential power bill 34 cents to $179.66 a month, the report said.
