Methane project will slash utility bills

Located at the Budd Inlet Treatment Plant in Washington State, US, a biogas and energy efficiency project costing over $2 million (€1.5 million) is set to save the sewage agency around $228,000 in annual utility costs.

The $2.4 million project will capture methane gas from a sewage treatment plant that will then be used to power machinery at the plant. The heat generated will be utilised by the newly constructed children’s museum adjacent to the facility.

As a result, the treatment plant’s carbon dioxide output will be reduced, saving 2.8kWh each year. This in turn reduces the region’s reliance on fossil fuels and relieves pressure on the local grid.

Aerating equipment can be installed to make the process operate faster and more efficiently. This apparatus is being fitted at the Budd Inlet plant that will see the utility costs drop by more than $48,000.

Costing $2.4 million the project has received a $1.7 million grant from Puget Sound Energy, the oldest energy utility in Washington State. This support reflects the company’s enthusiasm for investing in new technology for the development of renewable energy.
