Tuesday's announcement means Big Rivers' remaining customers will see their bills go up, but not as much as the utility had hoped. Originally, the utility wanted an additional $74.5 million dollars in adjusted revenue. However, the PSC approved $54.2 million, about $20 million less than requested.
Big Rivers applied for the increase, and began charging at the higher rates, after Century Aluminum's Hawesville Smelter announced it would no longer purchase power from the utility. Tuesday's ruling means customers of Big Rivers and its distribution cooperatives will receive refunds, with interest, to make up the difference between the higher rate and the rate approved by PSC.
When it's all said and done, residential customers will pay about $17 dollars more per month.
