100 per cent renewable electricity: the next steps

February 16, 2019 - 11:23 -- Admin

I’ve spend the last few days at a workshop on the transition to a renewable energy supply for Australia, which focused primarily on electricity. The presentations should be available soon, and I’ll write a longer post if I get time, but here are a couple of quick points I took away.

  • Adding storage to a system that is at or close to 100 per cent renewable will cost around $25/MWh, that is, about 2.5 cents/kWh
  • The big problem for Australia is transmission, to connect solar and wind resources to the grid. AEMO and AEMC are in denial on this. My view – we need to renationalise transmission immediately, and replace the current NEM alphabet soup with bodies that will plan for a rapid transition
