Samoa Plans Switch To 100% Renewable Electricity -- Using Tesla's Batteries and Grid Controller (fastcompany.com)

An anonymous reader quotes Fast Company: In seven years, the island nation of Samoa plans to run on 100% renewable electricity. Over the last year, the local utility has worked with Tesla to install a key piece of that plan -- battery storage, and also a software system that can control Samoa's entire electricity supply. In the past, like many islands, the country ran mostly on imported, expensive, and polluting diesel power. As recently as 2012, the country brought in 95 million liters of diesel. Spurred by the cost and the threat of climate change -- Samoa is at particular risk from sea level rise and new outbreaks of climate-related diseases -- the country has been ramping up the use of renewables, with five large solar plants, a wind farm, and hydropower plants. But as renewable energy grew, the grid struggled with reliability.

"It had gotten to the point where just the solar, combined, could provide over half of the entire peak demand for the island, but they were having quite a few challenges managing that efficiently," says JB Straubel, Tesla's chief technical officer.... Tesla installed two of its "Powerpack" battery systems, and also developed and implemented island grid controller software that can control both the batteries and all of the power plants. "If a big cloud comes over the island and the solar drops very quickly, we can control the battery to make up the difference so we don't have to start a generator immediately, and we don't have to keep a generator running even when it might not be needed," says Straubel.
