The Midcontinent Independent System Operator (MISO) is responsible for the transmission system and electricity markets in 15 states in the Midwest and the South, with its 45 million people covered making it the second-largest after PJM.
It has 32GW of standalone storage and 34GW of projects combining storage and another renewable, Johnson said, more than three times higher than end-2021 (around 10GW each). This is due to a combination of the passing of the Inflation Reduction Act as well as the approval of the MISO Long Range Transmission Plan Tranche 1 portfolio.
“The short-term thinking for us for storage deployments is ‘how does it show up as a transmission asset and get transmission revenues’. Cost is significant. In a perfect world the battery owner and the battery developer wants to get every revenue stream possible, but our systems don’t work that way,” Johnson said.
“We look at this and say if you are transmission-only we can model that and understand those benefits and revenues. If you are a generating asset, then we know what that is and we can again understand those benefits and revenues, and also work out how to make sure the asset is charged. Today we focus on those two areas. As our systems continue to develop and we learn more about batteries, we can think about how you can monetise other services.
” Our challenge is having a glut of projects that we need to work through and model. We need more projects to materialise, but those projects can cause congestion in the queue which delays the time to get studies done and determine their viability. It’s a bit of a chicken and egg scenario.”
