Expansion of grid-scale energy storage is important to enable the transition to variable renewable energy (VRE) sources such as wind and solar, and a green energy economy. The use of battery energy storage systems (BESS) is a key to enabling the growing penetration of VREs. BESS installations are classified as behind-the-meter (BTM) or front of…
Charging electric vehicles, Part 1: The numbers
It’s nice to envision that recharging an electric vehicle is as straightforward as filling up an internal combustion vehicle, but it’s not: there are multiple charging, power, and connector options as well as limitations. You’re driving your internal-combustion (IC) car, and the gauge indicates it’s time to get “gas” (of course, it’s actually gasoline). So […]
