(Colorado News Connection) An electric cooperative supplying power to western Colorado is pioneering energy independence for homes, businesses and farms.

They are creating a virtual power plant, a network connecting residential rooftop solar and battery storage to smart appliances such as heat pumps, electric vehicles and water heaters.

Lisa Reed, energy programs manager for Holy Cross Energy, said the microgrid can be tapped to keep the lights on when power lines from coal and gas fired plants are disrupted.

"Holy Cross Energy is implementing the use of virtual power plants to help with resilience, both for large events such as wildfires, but also smaller events, to keep our power reliable," Reed explained.

Holy Cross is standing up virtual power plants by providing affordable home battery storage lease-to-own options to members who subscribe to their Power+ program. The batteries store energy when demand is low and supply power during peak times or outages. Virtual power plants also reduce reliance on costly, polluting energy from coal and gas-fired units.

Tyler McDermott, regional organizer for the Western Colorado Alliance, said virtual power plants are also important for national security. If a hacker wants to take out a power grid, they can target a single conventional power plant but it is much harder to knock out a decentralized grid extending across entire communities. Microgrids also cost ratepayers 40 percent to 60 percent less than building coal or gas powered plants.

"We all want to pay less for our energy, we all want our lights to turn on when we flip the switch, we want our ACs to work in the hot summers," McDermott outlined. "Virtual power plants are the answer to one of the biggest problems that we're facing all across the nation but especially in rural communities."

Reed noted networked residential and business batteries also help community members save money on their electric bills in the middle of the day, when energy from conventional power plants is the most expensive.

"Holy Cross Energy discharges those batteries onto the grid to reduce our peak load, thus saving money for our members in power supply costs," Reed added.
