Corporate credit rating: BBB+/Stable/A-2 Standard&Poor's views the announcement by DTE Energy Services that it will jointly build a $160 million, 320 MW natural gas-fired peaker with Entergy Wholesale Operations as neutral for parent DTE Energy Co.'s credit quality. Standard&Poor's has already factored into DTE Energy's ratings the expectation of an expansion of its unregulated businesses in an attempt to grow consolidated earnings. The gas will be provided by the Vector Interstate Pipeline (1 billion cubic feet per day), which is partially owned (25%) by DTE Energy.
