Capacity market projects

Megascale battery projects don't make logical sense. Small battery projects connected to MV don't make logical sense. Depending on who you ask, you will likely hear one of these statements. Yet, both strategies are actively deployed in the market. Who is right? Maybe both. Ultimately, it usually comes down to the Excel spreadsheet.

Looking at the battery data from Capacity Market for delivery years 2027–2030, the top 17 projects (out of 174 in total) account for over 50% of the total capacity contracted (~5 GW) and nearly 50% of the total probable projects size (~13 GW after removing de-rating factor).

The landscape is shaped by both small projects (under 5 MW) and massive installations (over 200 MW).
