FIRSTLIGHT POWER RESOURCES, INC. et al v. ACE AMERICAN INSURANCE COMPANY et al
"16. On or about May 1, 2010, Plaintiffs commenced the dewatering (i.e., draining) of the upper reservoir for the purpose of facilitating repairs to the Power Station and maintenance to the upper reservoir.
17. The dewatering process involved pumping out water from the upper reservoir through the Power Station and down to the lower reservoir.
18. During this process, a significant amount of silt (approximately 200,000 cubic yards) unexpectedly slumped and entered the Power Station , thereby physically injuring the Power Station.
19. The silt hardened and clogged the pressure shaft, the connecting penstocks, the turbine units, and the tailrace tunnel, which caused a complete shutdown of operations from early May to late November 2010.
20. In addition to the cost of remedying/repairing the physical loss and damages at the Power Station, Plaintiffs sustained a loss of revenue and business interruption associated with the extended shutdown of operations."
