A solar power initiative, initially granted a construction permit in 2020, is on track to commence electricity production by late 2027. Recently, Grant County Public Utility District (PUD) commissioners sanctioned a power purchasing contract with Quincy Solar. This facility is expected to generate 120 megawatts of power annually, strategically positioned between the Grant County International Airport and the PUD’s Rocky Ford substation. All energy from this project will exclusively supply the PUD under a 20-year agreement.
The financial terms of the agreement stipulate that the PUD will pay approximately $70 to $72 per kilowatt-hour for the solar-generated power. This is significantly higher compared to the $20 to $30 per kilowatt-hour cost from the PUD-owned Wanapum and Priest Rapids dams. The PUD’s chief customer officer noted that the pricing reflects prevailing market conditions, citing recent hikes due to inflation and tariffs. Washington State, in particular, faces elevated costs due to state-mandated generation goals and specific contracting requirements.
Quincy Solar initially sought development permits for this venture back in 2020, having long sought a suitable energy off-taker. This contract aids the PUD in achieving its state-mandated renewable energy objectives, which include a requirement for 15% of its electricity to originate from renewable sources, such as solar or wind generation within the Columbia River Basin.
Further aligning with these objectives, the PUD maintains existing contracts with various suppliers and incorporates hydropower, which aligns with renewable standards. Efforts have been made to increase efficiency at the Priest Rapids and Wanapum dams by installing fish bypass systems, reducing the need to spill water for salmon recovery and thereby optimizing energy use. Additionally, a long-term project to upgrade turbines and generators at these dams is underway, expected to complete by decade’s end, enhancing electricity generation efficiency that contributes toward the renewable energy targets.
The state further mandates that 80% of the PUD’s electricity derive from non-greenhouse gas-emitting sources, with necessary mitigation for the remaining 20%. Should the solar facility not reach its expected capacity, Quincy Solar is obligated to pay damages until it fulfills its output promise.
While the Port of Moses Lake possesses industrial land nearby, the solar facility is not situated on port territory. According to Grant County’s Development Director, the site selection meets essential criteria for solar projects, including access to electrical transmission capacity and using previously utilized land that is neither irrigation farmland nor currently developed.
Your World Now
The integration of this solar power facility embodies a significant step toward renewable energy adoption, directly impacting the local community and energy consumers. With the rising cost of solar energy and heightened state environmental regulations, residents may anticipate shifts in electricity pricing structures. Although initially more expensive, investments in solar energy support environmental sustainability and align with broader goals to reduce carbon footprints.
Community members may experience benefits in terms of cleaner energy and potential job opportunities related to the construction and maintenance of the facility. Additionally, the long-term contract with Quincy Solar assures a stable supply of renewable energy, contributing to energy resilience and security for the region. This project highlights the state’s commitment to transitioning to a sustainable energy future, which could also serve as a model for other regions aiming to enhance their renewable energy portfolios.
