Contact UsWith rising energy costs and the worsening climate crisis, some wastewater treatment plants have started using solar energy. Because solar adoption at wastewater treatment plants is still relatively new, there is little known about these facilities, including where they are, what drove them to choose solar, and if solar has been a success.
It's also a necessity. Water treatment must be able to function no matter what. So, if there's a power outage, a water treatment plant has to have a backup. Most treatment plants run on energy generated from fossil fuels or nuclear power, but some are using renewable energy, specifically solar energy.
So in some cases, wastewater treatment facilities are— the municipalities are installing the solar on site and directly consuming that electricity. And many other scenarios, the municipality is entering what's called a power purchase agreement with a solar developer.
A solar company takes the upfront cost responsibility for owning and operating a generating system. They benefit from the solar energy credits. A water agency, on the other hand, pays only for the kilowatt hours of energy used, typically at or below current energy costs. Water agencies cannot take direct advantage of the solar energy credits. The solar company can potentially be cash positive on day one due to these credits, while the water agency does not have this insulation from volatile and rising energy prices.
