Nelson Energy LLC told the Federal Energy Regulatory Commission in a March 18 update that some issues are being cleared up and it is nearing a likely license application on a hydroelectric project in Minnesota.
BOST1 Hydroelectric LLC, for which Nelson Energy is acting an agent, obtained in 2009 from FERC a preliminary permit to evaluate the hydroelectric potential at the Coon Rapids Dam. In September 2013, FERC extended the term of the preliminary permit until Oct. 1, 2015. The development activities during the initial term of the permit were delayed due to the uncertain future of the dam on which this project would be built, the update noted.
The Coon Rapids Dam was constructed in 1912-1913 and provided hydroelectric power to the Twin Cities area until 1966. The dam is currently owned by Three Rivers Park District, with a recent dam rehabilitation project administered and funded by the Minnesota Department of Natural Resources under a joint powers arrangement. The rehabilitation of the dam involved the removal of the existing pneumatic gate system and the installation of steel crest gates on the crest of the existing spillway. The other major element involved the construction of a stilling basin downstream of the eastern section of the overflow spillway. The rehabilitation project began in 2013 and was completed in late 2014.
BOST1 originally envisioned a 10 MW-12 MW project here using two Kaplan turbines. The current works centers on utilizing the HydroMatrix turbines concept.
The update noted: “BOSTI is committed to developing the license application meeting the requirements of the Federal Energy Regulatory Commission (FERC) and submitting this within the term of the extended preliminary permit. BOSTI completed a draft license application in November 2014. A copy of this draft license application may be found on the Nelson Energy website www.nelsonenergy.us.”
