Seattle City Light and nine other organizations that have helped the Seattle Mariners reduce the environmental impact of Safeco Field operations will be recognized before tonight’s Earth Day game vs. the Houston Astros.
City Light recently provided energy efficiency incentives to help the Mariners replace 579 field and work lights with energy efficient LEDs, which made Safeco Field the first Major League Baseball stadium with all LED lighting for its playing field.
The lighting upgrade will reduce the Mariners’ electricity consumption by about 778,000 kilowatt-hours and save the team about $54,000 per year.
City Light supports energy conservation as its first resource of choice to meet the energy needs of our customers. Helping customers reduce their energy consumption through efficiency upgrades also is more cost-effective than purchasing additional electricity on the energy market or building a new power plant.
City Light is providing about $196,000 in incentives for the project, which is about 2.5 cents per kilowatt-hour saved.
For tonight’s game, the Mariners used City Light’s Green Up program to purchase 47,000 kilowatt-hours of electricity from renewable energy resources, including wind farms and dairy gas plants. That’s the expected energy consumption for the entire stadium during the game.
Seattle City Light is the 10th largest public electric utility in the United States. It has some of the lowest cost customer rates of any urban utility, providing reliable, renewable and environmentally responsible power to about 750,000 Seattle area residents. City Light has been greenhouse gas neutral since 2005, the first electric utility in the nation to achieve that distinction.
