OREANDA-NEWS. S&P Global Ratings raised its rating to 'BBB+' from 'BBB' on Mackinaw Power LLC's $288.9 million ($118.85 million outstanding as of June 20, 2016) senior secured notes. The outlook is stable.

"The rating action reflects our improved financial forecast for debt service, resulting in a higher preliminary stand-alone credit profile," said S&P Global Ratings credit analyst David Lum.

The stable outlook reflects our view of predictable cash flow from the power plants during the contracted period and less performance risk because the remaining assets in the Mackinaw Power portfolio are based on combustion turbine peaker technology.
