Solar Array Added to Power Agricultural District’s Irrigation Systems

Tranquillity Irrigation District, which serves the water needs of the 10,750-acre agricultural community of Tranquillity in Fresno County, today announces plans to build a 1.8 megawatt ground-mounted solar tracker system that will provide enough electricity to meet 50 percent of the agency’s energy demand. Borrego Solar Systems Inc., a leading designer, developer, installer and O&M …

“[…] Tranquillity will save a net $10 million over the 25-year term of its power purchase agreement (PPA)—a financing mechanism that enables customers to invest in solar without any upfront costs. The District will buy the energy produced from the system owner at a set price over the PPA agreement term.

“Solar was clearly the best use for our site, especially considering the savings we’ll realize for our residents through the PPA – it’s truly a win-win,” said Danny Wade, general manager of Tranquillity Irrigation District. “The reality is that we will continue to be plagued with limited water resources for the foreseeable future, and solar is a sustainable solution to help us deal with the resulting energy demand and cost increase due to the drought. Any water district in the state should be investigating whether solar works for them.”

Given the ongoing drought in California, the District has needed to use its wells more than it had pre-drought. As a result, more electricity is needed to power the pumps bringing water toward the surface. The District is trying to provide water to its landowners and the community of Tranquillity as efficiently and economically as it can. For example, the District recently received a $5 million grant from the California State Department of Health to build a necessary water treatment facility. The solar tracker system will be placed adjacent to the treatment facility on land already owned by the District. […]

In its first year of operation, the array will generate an estimated 3.3 million kilowatt-hours of electricity— enough to power approximately 450 homes. The installation will offset more than 760 metric tons of CO2 equivalents annually, which is the equivalent of taking 162 cars off the road for a year or the amount of carbon sequestered by 630 acres of mature U.S. forests each year.


Tranquillity Irrigation District was formed January 22, 1918, as a public agency designed to serve the local community with water supplies. It is the second oldest such agency in Fresno County. A Board of Directors elected from the community at-large governs the District. The District is approximately 10,750 acres in size and is located in the west central portion of Fresno County in the Great Central Valley of California. The District farmland produces a variety of commodities including: cotton (pima and acala), canning tomatoes, alfalfa for seed, sugar beets and almonds. Its principal community is the unincorporated town of Tranquillity.  […]”
