Hochul upgrades nuclear vision for N.Y.
In June of last year, New York Gov. Kathy Hochul called on the New York Power Authority—the state's public power utility—to add at least 1 GW of new capacity to the electrical grid through the construction of an advanced nuclear power plant in upstate New York to support the state’s decarbonization goals.
It was good news for the nuclear community, to be sure, but in Hochul's State of the State address in Albany earlier this week, she made that objective sound almost unambitious.
