MISO's own demand, wind, and solar forecasts, combined into the number generators actually plan against — with every input shown alongside it.
What will the Midwest's dispatchable fleet have to serve?
MISO net load peaks at 96,993 MW on Thu, 8 PM, against a low of 60,761 MW — a swing of 36,232 MW across the window. Net load is the heaviest area at 96,993 MW.

Every input is a point forecast with no confidence interval, and their errors do not cancel — a demand forecast running high and a wind forecast running low both push net load the same way, so this series can be wrong by more than any one of its inputs.
Net load is demand minus wind minus solar — the electricity the dispatchable fleet has to produce once the renewables have delivered what they are expected to. It is not published by MISO as a feed; this page composes it from three forecasts that are, and plots all three so the subtraction is visible rather than asserted.
MISO runs from Manitoba to Louisiana and carries a large wind fleet in its northern half. Net load is where that fleet's output actually shows up: a windy night can push net load far below what demand alone would suggest, and a still evening removes several gigawatts from the supply stack without a single unit tripping.
Watch the overnight hours. MISO wind often peaks when demand is at its lowest, so the net-load minimum is usually a wind story rather than a demand one.
A net-load point exists only for hours where all three forecasts do. The three feeds have different horizons, so this curve ends wherever the shortest of them ends — it is never extended by holding a wind or solar forecast flat past its own reach, which would invent the number the page exists to state.

Electricity demand minus the wind and solar expected to serve it. It is what the dispatchable fleet — gas, coal, nuclear, hydro, and batteries — is actually called on to produce, and it is the curve generators and traders plan around rather than demand itself.
Because its wind fleet frequently produces most at night, when demand is lowest. The two move in opposite directions, so net load falls much further than demand does — and rises sharply when a front passes and the wind drops.
The three inputs are. The subtraction is ours, and it is stated plainly for that reason: MISO publishes a demand forecast, a wind forecast, and a solar forecast, and this page combines them on matched hours without adjusting any of them.
