A chancery judge in Harrison County has affirmed that the certificate of public convenience and necessity for the Kemper County coal plant is valid.
The Sierra Club had argued that it was not, and that the Mississippi Public Service Commission should conduct a full round of evidentiary hearings before deciding whether to issue another one. The Sierra Club’s action was in response to the Mississippi Supreme Court’s kicking the issue back to the PSC earlier this year because justices said the original certificate, issued in 2010, did not cite sufficient evidence from the record of proceedings.
Commissioners issued a second certificate over the summer. Construction on the plant, which began in 2010, has continued while the litigation unfolded.
“Mississippi Power customers are the ones who will benefit from this important decision,” Ed Day, president and CEO of Mississippi Power, said in a statement Tuesday morning.
The Sierra Club will appeal Monday’s ruling, state director of the Mississippi chapter Louie Miller said. “We’ll probably ask for an expedited appeal,” Miller said in a phone interview, referring to the possibility that the appeal could languish at the supreme court for several months.
Public service commissioners ruled over the summer that they would not entertain any rate increases associated with the plant until the Mississippi Supreme Court had ruled on the latest round of litigation surrounding it. That ruling came after a hearing in which Mississippi Power asked for a 13 percent rate increase that would have generated about $58 million. Monday’s chancery court ruling now opens the door for the litigation to proceed to the high court.
Rate increase estimates attached to the plant have varied. Documents Mississippi Power filed with the commission in 2009 said rates would go up an average of 45 percent. In the order granting the second certificate, commissioners said rate increases would peak at 33 percent before going back down.
Day said earlier this year that the sale of the plant’s by-products would generate more revenue than originally anticipated, keeping rate increases under 30 percent.
The $2.88 billion plant is scheduled to begin operation in May 2014.
