We Don’t Have to Wait for Real-Time Markets to Bid Renewable Power Onto the Grid
Growing the amount of renewable power that’s available on the grid is equally as crucial for the energy transition as the ability to generate power from renewable sources. Fossil fuels continue to have the advantage because of market-bidding protocols that place their power on wholesale energy markets across the country, making it widely available to […]

The 5 Steps Utilities Should Take in 2021 to Prepare for a Carbon-Neutral Future
We’re at the electric tipping point as electric stoves, vehicles, and construction equipment displace the fossil fuel guzzlers of the past. Yet, before a carbon-neutral future can truly take off, utilities and the electric grid need to innovate. For the world to hit net-zero emissions targets by 2050, grid investments need to almost triple to […]

Is Vehicle-to-Grid Technology the Key to Accelerating the Clean Energy Revolution?
Neil Wright Vehicle-to-grid (V2G) technology is not new, but it is extremely nascent. To many, it is the natural progression from “smart charging,” whereby electric vehicles (EVs) are only recharged at the best time for the network, to a more holistic grid scheme.
