A forum hosted by the Pennsylvania Public Utility Commission to explore potential impacts of alternative fuel vehicles on critical infrastructure heard a good news, bad news scenario from the CEO of the PJM Interconnection, the regional grid operator.
PJM CEO Terry Boston told the forum that with smart grid controls in place and re-charging properly synchronized between midnight and 7 a.m., the electric distribution system could accommodate 25 million EVs, according to coverage of the forum in the Philadelphia Inquirer.
But without those controls, the scenario will look a lot different, Boston warned. "If all of those came home at 5 p.m. and plugged in, we would have a voltage collapse, and I would be seeking other business opportunities very quickly."
Experts also told the PUC forum at Drexel University that time-of-use rates would create a more efficient electricity system.
Todd Campbell, VP of public policy and regulatory affairs for Clean Energy Fuels, "urged the commission to not allow regulated utilities to compete with private suppliers by charging their ratepayers for the cost of refueling stations," the Inquirer wrote.
