California’s updated maps to the power grid – ICA 2.0 – went online as of December 28, offering insight at every point on the circuit which could affect how much solar can be attached.
ome projects take years to move through the interconnection queue. And it often costs thousands, or tens of thousands, to be told that your project won’t fit on the local grid for whatever reason. In markets like Massachusetts, you can then be asked to spend significant amounts of money to upgrade transformers, install new powerlines, or upgrade substations and then play the lottery that later developers take some of those upgrade costs onto their local projects. Things like this can kill the financials of otherwise viable projects.
California has taken steps to mitigate this risk by requiring electricity utilities to provide increasingly detailed maps of the grid. And the newest version of their Integration Capacity Analysis (ICA 20) maps went online as of December 28.
