Eigg isn't connected to the UK national grid. Instead we generate 90% to 95% of our electricity from wind, sun, & water (hydro). Community-owned Eigg Electric was switched on in 2008. Islanders are trained and employed to manage it. Electricity costs 28p per unit/kWh. Before 2008 each property had its own diesel generator. Now we have 24kW of wind, 110kW of hydro, 170kW of solar PV, storage batteries, and a back up generator. Next challenge is #netzero #renewables #eigg http://isleofeigg.org/eigg-electric/
Eigg Electric - The Isle of Eigg

@isleofeigg the "frequency controlled regulatory measures" are very interesting. I've worked in projects to reduce demand at low frequency but equally high frequency (too much gen) that's a nice problem to have. In my view there's no consequence of wasting electricity/heat in that situation 😉
