A group called Nevadans for Affordable, Clean Energy Choices is trying to get a proposal on the ballot that aims to bring more electricity providers to Nevada. The group filed a petition with the Nevada Secretary of State’s Office yesterday. Supporters would need to gather more than 55,000 signatures to put it up for a vote in November. The measure would amend the constitution to prohibit a legalized monopoly for electric service, and requires the Legislature to enact laws that clear the way for an open electricity market by mid-2023.
