Virtual Power Plants May Hold The Key To An All-Electric Future
Virtual power plants can help us use electricity more wisely and reduce the need for expensive new generating resources.

Sydney, the largest city in Australia, has signed a power purchase agreement that allows it to source all of its electricity from renewables.
Today’s electric cars have larger batteries that need higher power to recharge them. Could that be a problem for utility companies?
Hawaiian Electric (HECO) recently added 2.5MW of grid services to its grid, allowing it to store energy during peak solar and wind production periods, and did so without any traditional batteries, flywheels, or pumped hydro. Even better, the hardware required is very minimal, and in fact, most of it already exists in every residential grid in the world.
We are now realizing — 50 years too late — that burning stuff to make electricity and run all our vehicles is making our planet sick, to the point where one day soon it may be unable to support life as we know it. But how to address that situation while continuing to insure we have all the electricity we need when we need it?
Today’s electric vehicles are essentially big batteries on wheels, with a significant capacity to store and discharge energy. The average utilization of privately owned vehicles is 5%, meaning that the average battery on wheels is underutilized for the vast majority of its useful life.
Economics are driving Northern Indiana Public Service to do what the Clean Power Plan could not — shutter one of the dirtiest coal generating stations in America.
Solar and wind power are absolutely predictable when it comes to variable costs. By contrast, coal and gas power are altogether too variable to be reliable.
Hawai’i’s own Kona Brewing Company on the Big Island is tapping into the power of the sun to allow people to tap into its beer without guilt. The company is installing a new solar-plus-storage installation with the help of EnSync Energy and Holu Energy that will allow the company to crank out nearly 7,000 cans of ‘Liquid Aloha’ per hour.
The road to renewables will not be paved by the environmentalists. Instead, the path is being cut by the accountants, and health care provider Kaiser Permanente is showing how to do it right.
