From a Tom Content blog post on JSOnline:

We Energies’ newest coal-fired plant is generating power, after “significant progress” in construction over the past three months, the company’s chairman said Thursday.

The coal plant consists of two coal-fired boilers next to an older coal plant on Lake Michigan in Oak Creek. The first new boiler began burning coal earlier this month and has been running at 25% of maximum power in recent days, said Gale Klappa, We Energies chairman and chief executive.

Bechtel Power Corp., the contractor on the project, also has made progress on building the second boiler, which is now 74% complete, Klappa said.

The $2.3 billion project is the most expensive construction project in state history, as it’s roughly double the combined cost of building Miller Park and rebuilding the Marquette Interchange.
