Adding 2,000 amps of new service would exceed the capacity of our existing power plant in Stehekin. Customers need to consider carefully before adding any new electrical loads to the system.The existing hydro system has very little room left for growth, and the community needs to make the most out of the limited power that is available. Could the emergency generators (D1 or D4) be used to supplement generation until a long-term solution is found? No, the existing hydropower turbine and the smaller 75 kW diesel generator (D2) are the only two generators that can be used routinely to provide power to the Stehekin community. The emergency generators (D4 and D1) are only to be used during emergencies, or when routine maintenance is being performed. Our air quality permit does not permit us to operate the emergency generators to meet additional load growth on our system. Will the proposed battery storage system provide enough additional capacity to meet Stehekin’s growing power needs? The PUD plans to install a battery energy storage system in Stehekin that would run in parallel with the plant’s existing hydro and diesel generators. The proposed system would have the ability to provide up to 250 kW of additional capacity. The battery would be designed to provide additional power whenever the Stehekin loads exceeded the capacity of the hydro system, or if the hydro system is shut down for short periods for maintenance. In order to store this energy for future use, the battery needs to recharge. It would recharge during times when the loads were lower than the hydropower generator output. Increased loads in the community could reduce the amount of time available for the battery to recharge. Could solar power work in Stehekin to supplement generation at the hydro? With our current system, solar electric systems will not do much to reduce the need to run the diesel generators at the Stehekin plant.The proposed battery energy storage system should allow us to store excess solar and hydro generation to be used during peak periods instead of having to run the diesel generators. Why can’t the PUD upgrade the existing generating plant instead of pursuing conservation or other solutions? Energy efficiency and shifting the time of day that certain kinds of equipment operate is the least costly way to get the most out of our existing generation system. Any solutions will require cost sharing with the customers, and these more expensive solutions could impact rates in Stehekin.
