What it does
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
This bill requires the Public Service Commission to conduct a nuclear power siting study and to submit a report to the legislature containing the results of the study no later than 12 months after the bill takes effect. The study must satisfy certain requirements specified in the bill.
The bill also requires PSC to take final action on an application for a certificate of public convenience and necessity (CPCN) for a large electric generating facility that contains an advanced nuclear reactor within 150 days after the application is complete, unless the chairperson of PSC extends the time period for no more than an additional 150 days for good cause. Under current law, a person seeking to construct a large electric generating facility must obtain a CPCN from PSC.
