Access to water, and water rights in general, are critical to life in the Desert Southwest. That’s why two candidates for the Imperial Irrigation District Area 2, which includes El Centro and western Imperial County, say they take that mission very seriously.
The Vallecitos Water District is pursuing greater use of renewable resources, increasing capacity to the electrical grid, and reducing long term operational costs with an innovative solar power project.
The west solar array is installed on top of the Vallecitos Water District’s 33-million gallon reservoir with 2,300 solar modules and eight 80 kw inverters. The east array is located on top of the 40-million gallon reservoir with 2,900 modules with ten 80 kw inverters. Photo: Vallecitos Water District
In 2017, the Vallecitos Water District Board of Directors agreed to pursue development of districtwide renewable power sources using existing open space to benefit the District and its ratepayers. The District worked with solar consultants Terra Verde Renewable Partners to evaluate and study the feasibility of three solar port locations. Two projects are now moving forward; two arrays at the pair of Vallecitos owned reservoirs in Twin Oaks, and an array at the (sewer) Lift Station #1, located on San Marcos Boulevard.
The projects are structured under a Power Purchase Agreement. A solar provider designs, builds, and maintains systems for 25 years. In turn, the District receives a reduced electricity rate from SDG&E over the 25-year term at the District’s 13 highest use meters. The District will become owners of the solar system after the 25-year maintenance term expires. No capital investment is required from the District.
“The project is a great benefit to Vallecitos customers,” said Ryan Morgan, Capital Facilities Senior Engineer. “Through our export of power into the electrical grid, we receive bill credits on these power exchanges. The District benefits directly through reduced power costs, and that cost savings is passed down to the customer ultimately in reduced water and sewer rates.”
Vallecitos Water District provides the project sites, working with SDG&E, the solar provider team, the District’s contractors, and the solar maintenance operator. The District’s water professionals work with solar power experts to guide the project through planning, design, and construction as a team.
Over the 25-year term, the District will benefit from a reduced electrical rate of 7.79 cents per kilowatt-hour (kWh) at its 13 highest use meters. It will also receive a rebate or credit on its export of power to the electrical grid. Savings to the District over 25 years are estimated at $8.3 million, which ultimately results in reduced water and sewer rates for customers. District staff locked in the maximum federal rebate by launching the project in 2019 and meeting a narrow window for grant funding.

The east array is located on top of the 40-million gallon reservoir with 2,900 modules with ten 80 kW inverters. The total production is roughly 3.6 MWh annually, enough to power 340 homes.

While the solar power project cannot prevent the potential for power outages due to rolling blackouts, the project helps to add capacity to the power grid when it is needed.
“The District wants to publicly thank Terre Verde Renewable Partners, Holt Renewables, and Kenyon Energy for their valuable roles in the success of this project,” said Morgan. “We also want to acknowledge the above and beyond effort of the District’s inspections team.”
The Twin Oaks Reservoir dual array is expected to be completed in November 2020. The Lift Station #1 site is expected to be completed in February of 2021.

We need it. We need it really, really badly. With wildfire after wildfire battering California since late summer, burning record acreage and killing at least 30 people in less than two months, weather experts have repeatedly said conditions conducive to critical fire risk probably won’t begin to subside until the first significant rainfall of autumn.
For more than a month after a wildfire raced through his lakeside community and destroyed his Napa County home, Kody Petrini couldn’t drink the water from the taps. He wasn’t even supposed to boil it. And, worried about harming his 16-month-old, Petrini wouldn’t wash his youngest son Levi with it.
Poseidon Water’s long, winding road to building a desalination plant in Huntington Beach could face its biggest obstacle yet if opponents prevail in the upcoming election.
Mo Mohsin has been trying to bring clean drinking water to the residents of the Cobles Corner mobile home park ever since he bought the property back in 2003. The struggle, however, has been all uphill.
Californians are understandably focused on the wildfires that have charred more than 3 million acres and darkened our skies – forcing us to find masks that protect us from both COVID-19 and smoke. But Californians should also pay attention to the multiple hurricanes that have devastated the Gulf Coast this season.
U.S. and tribal officials are celebrating completion of a $34 million fish bypass system at a Nevada dam that will allow a threatened trout species to return to some of its native spawning grounds for the first time in more than a century.
