SEIA South Carolina State Solar Policy Priorities & Highlights

SEIA is heavily engaged on H3659, which:

  • Eliminates the capacity caps on net energy metered systems, and extends the full retail rate for systems that are installed before 6/1/2021. The South Carolina Public Service Commission will determine the rate for systems installed on or after 6/1/2021.
  • Outlines terms for large scale solar projects that have been in the interconnection queue for years. These terms will apply until South Carolina’s IOU’s install solar to reach 20% of their peak demand.
  • Creates more transparency and competition in long term utility planning, the opportunity for additional community solar programs, and gives oversight to the PSC on rates and term paid to future large scale solar.
