Exelon last week sold its 67% interest in Safe Harbor Hydroelectric Project, one of four run-of-the-river hydro facilities on the lower Susquehanna River, to Brookfield Renewable Energy Partners, L.P. for $613 million.
Brookfield operates 6,000 MW of generation, primarily hydro, in the United States, Canada and Brazil. It will be sole owner of the facility when the deal closes.
The deal is supposed to be finalized by the third quarter of this year, subject to regulatory approval.
Exelon inherited two-thirds ownership of Safe Harbor when it bought Constellation, parent company of Baltimore Gas & Electric. It still owns and operates Conowingo Hydroelectric Generating Station, the last dam on the Susquehanna River before it empties into the Chesapeake Bay, and Muddy Run Pumped Storage Facility, which is perched on the banks of the Susquehanna upstream from Conowingo.
Safe Harbor went into operation in 1931. It was a joint project of the two companies that would become PPL and BG&E. An affiliate of the LS Power Group purchased PPL’s share in 2011, and Brookfield bought it from LS Power in March of this year.
There are three other power-producing dams on the lower Susquehanna in Pennsylvania and Maryland. Furthest upstream is York Haven Dam, a small, 20-MW facility south of Harrisburg, Pa., owned by Olympus Power. Next is Safe Harbor followed by Holtwood Hydroelectric Plant, both between Lancaster and York Counties in Pennsylvania. Originally a 108-MW plant, PPL completed an expansion of Holtwood in 2013 that added another 125 MW.
The Conowingo dam is a 630-MW facility on the Susquehanna, between Harford and Cecil Counties in Maryland.
