With a PPA you only pay for kWh generated. With cash purchase (or a lease), if system underperforms, you lose incremental value of the electricity that you have already purchased, but would be receiving free energy going forward once the system has paid for itself. as well as any. Local laws will impact how the system or energy is likely purchased / financed. District will need to determine a process that is most conducive to their laws and needs. What are the various procurement methods? In CA, using Government Code 4217 a public entity can procure a solar system from a. Small wastewater treatment plants (WWTPs), which treat less than 1 million gallons per day (MGD), make up 79% of wastewater utilities in the United States and play a crucial role in our communities. WWTPs and drinking water systems account for approximately 2% of energy use in the United States. This article explores the benefits of solar for water treatment plants in the context of these challenges. Cost Savings: Wastewater treatment plants are typically energy-intensive operations.

With 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.
Can a municipality install a solar system on a wastewater treatment facility?
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.
What is the difference between a solar company and a water agency?
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.
