What is the size of the CHP Unit being considered to replace Unit 9?

MPW is evaluating different sizing options for the CHP unit ranging from 50 megawatts (MW) – 140 MW. Capital cost estimates for a unit at the top end of this range are around $180 million, but a smaller configuration would likely require less financial capital. (As a comparison, when Unit 9 was built in the late 70’s the cost was $250 million, or approximately $680 million in today’s dollars).It is most likely that the unit will be sized to cover only a portion of MPW’s load demands, leaving room to fill out our portfolio with additional diversity, including increased renewables. Having an “open” position in our portfolio would allow MPW to take advantage of low market pricing when available and continue to evaluate resource options as technologies improve in the coming years.
