"World's largest microgrid" that seems to be significantly smaller than Orkney islands who are currently running at 105% of need via renewables, and complete conversion of housing and heat. They're well on with adding storage batteries to houses too. Much of it community owned. I think they now have 500+ generation sources smart controlled from where the old diesel power plant used to be. They're also working at replacing diesel ferries with hydrogen. Create hydrogen from sea water from the renewable surplus to power initially the ship auxiliary systems, then replace the ferries with fully hydrogen powered. 45% from renewables seems absurdly limiting and low, except as short term interim step to 100%+
