Tesla and California electrical utility Pacific Gas & Electric (PG&E) are launching a pilot program that may use Tesla Powerwall house vitality storage battery packs as a “virtual power plant” to again up the grid.
On June 22, Tesla invited roughly 25,000 Powerwall house owners who’re PG&E prospects to take part in this system, based on PG&E. In the 2 weeks following the announcement, greater than 3,000 prospects expressed curiosity in collaborating, and greater than 1,500 formally enrolled within the pilot program.
“Enabling Powerwall customers to support the grid and their community is a necessary and important part of accelerating the transition to sustainable energy,” Drew Baglino, Tesla senior vp of powertrain and vitality engineering, mentioned in an announcement. “We seek to partner with utilities and regulators everywhere to unlock the full potential of storage to bring more renewable, resilient, and less costly electricity to everyone.”

Participating prospects’ Powerwalls will collectively kind a “distributed” battery that may take in extra vitality in periods of low electrical energy demand, and discharge it again into the grid in periods of excessive demand, based on PG&E. It’s one facet of the utility’s Emergency Load Reduction Program, a five-year pilot program launched in 2021 that seeks to incentivize diminished electrical energy use in periods when the grid is especially harassed.
In this case, Powerwall batteries can be directed by PG&E to discharge throughout the high-demand hours of 4:00 p.m. to 9:00 p.m. Customers will get $2.00 for each incremental kwh of electrical energy discharged throughout these occasions—doubtlessly a big income generator for these prospects, as PG&E’s baseline residential fee is 32 cents per kwh. They can nonetheless use the Tesla app to order sufficient energy for private use, in addition to decide out of this system, PG&E famous.
Using batteries on this method will help steadiness the grid by avoiding sudden spikes in demand. A extra balanced grid means outages are much less possible, and it could additionally make EV charging extra dependable.

California goals to finish gross sales of most new non-electrified automobiles by 2035, however a 2020 report advised the state’s grid will want huge updates to assist all of the EVs it is sculpting its coverage round. And 2021 warmth waves prompted public alerts about EV charging in California.
Ramping up vitality supply to satisfy summer time warmth waves this 12 months can be costlier and carbon-intensive, because of the ongoing drought. The drought is limiting hydro-electric producing capability, forcing California to rely extra on carbon-intensive vitality sources, the federal Energy Information Administration (EIA) mentioned final month. That successfully will increase the carbon footprint of EVs charged from the California grid, too.
PG&E and Tesla’s trial is only one of a number of pilot packages methods to clean the grid by means of bidirectional charging—some utilizing the automobiles themselves because the bidirectional backup energy banks. That’s one thing not but enabled in Tesla automobiles.
