Not sure why ISO NE is at a relatively high price this morning.
Demand is moderate at 12,412 MW.
The "marginal fuel" was wind when I looked at it about ten minutes ago; wind is very inexpensive.
I saw that the share of hydro was increasing and I assume / assumed that's why prices were moving up.
And now, ten minutes later, the marginal fuel is "hydro, wind."
Hydro is very expensive and now moving up. Ten minutes ago, share of hydro and renewables were equal at 14%. Now ten minutes later hydro is at 16% and renewables are at 14%.
The question is why? Why is not natural gas the marginal fuel?
ISO NY is similar, running about $100 / MW this morning.
