Lawyers for the town of Christiana, Wisconsin–whose 1,300 residents live around 30 minutes southeast of the state capital of Madison–filed a lawsuit in late May seeking to overturn a regulatory decision approving a $650 million, 300 MW solar facility and 165 MW battery storage system being developed by Chicago-based Invenergy.
The Koshkonong plant was approved as a merchant generator, limiting the extent of regulatory review. But plans call for the solar facility to be sold to Madison Gas and Electric and utilities owned by WEC Energy Group. A separate regulatory filing covers that proposed transaction. The sales price includes $412 million (or $1,373/kW) for the solar facility and $237 million (or $1,436/kW) for the battery story system.
