The microgrid will be partly powered by a 17 MW wind farm located 4 km off the coast of Anchorage. The project was initiated by local utility Chugach Electric Association Inc, as part of wider efforts to identify technologies that enable the integration of more renewable energy sources.
ABB will use its PowerStore battery system, with battery and flywheel storage capabilities, in combination with its Microgrid Plus control system, which will monitor the grid and ensure proper load sharing between the two storage systems.
“This innovative solution shows how energy storage technology can boost renewable energy penetration in Alaska,” said Chugach Electric Senior Vice President of Power Supply Paul Risse. “It has far reaching implications for renewable projects in Alaskan communities.”
“We are delighted to partner with Chugach Electric to build this microgrid and enhance reliability of power supply,” said Massimo Danieli, Managing Director of ABB’s Grid Automation unit. “Integration of renewables is a major focus area of our next level strategy.”
