Big batteries can store power when the sun doesn't shine

SNIPPET:

What is the difference between a battery and a power source? It is sometimes hard to distinguish. If you build a dam and capture the energy of falling water, it is considered power generation from a power source, namely gravity. But if you pump water up a hill and store it behind a dam until you need it, that's acting as a battery; it is not making energy, it is just storing it. It is a really important distinction; it is one of the reasons we are not fans of hydrogen, considering it more a battery than a fuel.

Diane Cardwell of The New York Times writes about The Biggest, Strangest "Batteries" and explains how really, anything that can store energy and release it later is a battery.

Tesla Wins Contract for South Australia Energy Storage Project 

July 7, 2017

By Perry Williams, Bloomberg

SNIPPET:

Elon Musk’s Tesla Inc. has won a tender to supply what the billionaire says is the world’s largest lithium-ion battery to back up the state of South Australia’s blackout-plagued power grid, making good on a promise first made over Twitter four months ago to help solve the state’s energy woes.

Tesla will provide 100 MW of storage by Dec. 1, pairing it with a wind farm at Hornsdale north of Adelaide operated by France’s Neoen, according to a statement on Friday from South Australian Premier Jay Weatherill. The system, which will have capacity of 129 MWh, will provide enough power for more than 30,000 homes, Tesla said in a separate statement.

We’re talking about something that’s three times as powerful as the next biggest battery installation in the world,” Musk told reporters in Adelaide.

Musk had previously promised to build the system and get it working within 100 days of a contract being signed or Tesla would provide it free, a vow he backed up on Friday.

Quote

“We actually insisted when doing the contract that we be held to the 100 days or it’s free,” Musk said. “That’s what we said publicly, that’s what we’re going to do.”
