RICHLAND, Wash.- Energy Northwest hit a milestone Wednesday.
The public power supplier celebrated its 50th Anniversary.
In 1957, the Washington Public Power Supply System went on-line.
Board members gathered Wednesday said since then, there have been some tough times, but they plan on continued expansion over the next 50 years.
Benton and Franklin County have been members from the start, and leaders say another 50 years will benefit local ratepayers.
"This has been one of the best ways that we can keep our energy prices low, reliable and it is clean," said Bill Gordon with Franklin County PUD.
Energy Northwest reports more than $200 million in annual revenues, 1,100 employees and 1,300 megawatts of generation.
They are one of the region's main power suppliers.
