Supt. Jason Gagnon said the solar arrays have resulted in a total reduction of $195,855 in electrical costs at the precinct's Wastewater Treatment Facility.

Solar arrays at treatment plant are paying off

Giving a tour of the North Conway Water Precinct’s newest solar array, Superintendent Jason Gagnon said Monday he would have good news to share at Wednesday night’s annual precinct meeting about the two arrays’ impact on electrical savings.

The latest array, installed in 2021, joins one installed in 2010. Gagnon said they have  resulted in a total reduction of $195,855 in electrical costs at the precinct’s Wastewater Treatment Facility.

He said that 2022 was the first year of “normal” at the facility after the pandemic started. “When we compare average electricity use from 2017-19 (the pre-COVID normal) with electricity use in 2022, we estimate that the annual savings realized from the new solar array alone are more than $155,000 over those previous years,” Gagnon said.

Researchers found that 6,256 cities across 124 countries could, in theory, meet all their electricity demand from solar panels deployed on nearby water reservoirs.

Floating solar panels could completely power thousands of cities

Thousands of cities around the world could power themselves entirely with solar panels floating atop water reservoirs, according to new research. It’s a relatively easy way to generate renewable energy locally while also conserving water.

Solar arrays suspended over water, or floatovoltaics, work similarly to those spread out over land. The panels sit on a raft instead of on parking lots, rooftops, or other grounded mounts. But they haven’t been deployed in many places around the world yet and only produced as much electricity as less than 1 percent of the world’s land-based solar farms in 2020. Now, a new study published in the journal Nature Sustainability shows just how much potential cities could tap into with this emerging technology.

Lightsource bp has built a pair of solar farms in CO that double as carbon sinks and help to preserve 3,000 acres of shortgrass prairie, too.

New solar farm is a carbon sink & prairie preserver, too

A movement is afoot to quash utility-scale solar development on farmland in the US, but the case for rural solar keeps expanding in new and different directions. In the latest example, Lightsource bp has built a pair of solar farms in Colorado that double as carbon sinks and help to preserve 3,000 acres of shortgrass prairie, too.

Solar developers like farmland because it is relatively flat, treeless, and exposed to sun. Roads and transmission infrastructure are pluses, too.

As for local opposition, that is a matter of local concern. However, if the objections come down to aesthetics and appropriate use of land, that is a matter of historical perspective. Farms look bucolic enough on the outside, but beneath those amber waves of grain is formerly virgin land that has been stripped of its natural state, robbed of its biodiversity, commercialized, and industrialized for generations with machines, herbicides and pesticides.

San Joaquin Valley may become home to vast solar arrays turning fallowed farmland into a source of clean energy while sustaining local jobs.

Panel finds valley solar can help decarbonize state but local needs loom

The San Joaquin Valley may soon become home to vast solar arrays turning fallowed farmland into a source of clean energy while sustaining local jobs. But it won’t be easy pulling it off in a way that’s equitable to local communities.

That much was clear during an online panel the Public Policy Institute of California hosted earlier this month titled “Solar Development in the San Joaquin Valley.” It took participants through layers of complications that remain to be addressed if the valley is to meet its potential as a major component of California’s efforts to become carbon neutral by 2045.

Dulles solar farm would be built on more than 835 acres on land that would power the larger Northern Virginia electrical grid.
,

Dulles solar farm would be the nation’s largest at an airport

Dulles International Airport could soon be home to the largest airport-based solar and battery development in the United States, one that at peak production could provide enough energy to power more than 37,000 Northern Virginia homes.

The solar farm would be built and managed by Dominion Energy on more than 835 acres on land. It would include a solar array capable of producing 100 megawatts of solar generation and a 50-megawatt battery storage system. The power generated would feed the larger Northern Virginia electrical grid.

Once built, Dulles would join a growing number of airports across the country looking to solar developments as a way to meet sustainability goals, save money on electricity and generate revenue from land that might otherwise be undeveloped. The project is one of dozens the Virginia utility company is building as it shifts to meet the mandates of a sweeping clean-energy law that state lawmakers passed in 2020.

Roll-A-Rack has developed a roll-forming solar racking system that captures rainfall on solar panels that can be used for irrigation.

Rollout solar racking collects rainwater, cuts land-use requirements

Ohio-based Roll-A-Rack announced it has developed a roll-forming solar racking system that captures rainfall on solar panels. Harvested rainwater can be used for irrigation. The product is designed for flat roofs or ground-mounted systems. 

The compact system requires only 11 inches between rows of panels, significantly cutting down the amount of space that is normally required for erosion control by planting vegetation. The company said the solution requires half the land to produce the same amount of energy as conventional racking systems.

According to the development permit request, more than 1,800 people are expected to be employed when the warehouse is operational.

Desert Hot Springs to house one of largest rooftop solar arrays in California

Desert Hot Springs will soon be home to a warehouse with one of the largest rooftop solar arrays in California, officials announced today.

The Viento logistics center will be located by Interstate 10 near Little Morongo Road. A sortable multi-story e-commerce warehouse and distribution center for consumer products, it will encompass about 3.5 million square feet and stand approximately 105 feet high.

Two environmental groups, Oswit Land Trust and the Tahquitz group of the Sierra Club, had filed an appeal against the project, asking the City Council to require a new initial study to determine if the project requires a mitigated negative declaration or an environmental impact report, but the two groups settled with the city recently.
