Commissioners approved Tucson Electric Power Company’s (TEP) revised Distributed Generation Interconnection Manual. The creation of these manuals was required following the Commission passing rules dealing with the interconnection of distributed generation facilities. TEP’s manual lays out technical and safety requirements that customers within its service territory must follow when interconnecting a distributed generation system, such as residential and commercial solar projects, to the existing grid. The manual is meant to create a standardization process for customers.

TEP’s manual was initially approved at the Commission’s February 2022 Open Meeting, however, following the passage of AriSEIA proposed amendments at that meeting, a revision to the manual was necessary. After several meetings between AriSEIA, TEP, and ACC Staff, the manual was revised to include information regarding Meter Socket Adapters (MSA), detailing their use for generating facilities. The manual was updated to better preserve the Super-Fast Track and Fast Track designations, allowing for faster review tracks for qualified projects. The revised manual also clarifies study cost fees customers are responsible for prior to beginning any study. TEP’s revised manual does not prematurely require inverters to comply with the IEEE sections that are not yet developed or for which equipment is not yet capable of compliance. Further, the manual modified its requirements around transfer trip infrastructure so as not to be overly burdensome, thereby reducing costs for large installations. Finally, the revised manual includes an additional section that provides a list of scenarios meriting an extension of time.

The Honorable Mark Kelly
U.S. Senate
516 Hart Senate Office Building Washington, DC 20510
  
Dear Senator Kelly,

Last year, we wrote seeking your support for a robust energy tax package that would help the solar industry meet our nation’s climate goals. Now, as the Senate gets closer to considering reconciliation legislation, we are asking for your active support in getting this measure over the finish line. To create jobs and economic prosperity for millions of Americans, we ask for your strong support for passage of the reconciliation energy tax package that will spur solar and clean energy in Arizona, including a 10-year extension of the investment tax credit (ITC). Extending the ITC and adding the option to utilize the credit directly is critical to Arizona’s solar development.
 
Arizona is an incredible solar state, ranking fifth nationwide in overall solar installed, and second in solar energy potential. This has resulted in tremendous economic growth and future potential for Arizona businesses. Hard work, small business ingenuity, and an abundance of sun has made Arizona home to more than 300 companies and more than 7,300 jobs working to advance solar innovation and energy freedom. There are multitudes of young people who are looking to enter careers in solar, thanks in large part to the excellent programs at Arizona State University and the University of Arizona. These jobs range across multiple fields, including design, development, construction, and operations & maintenance. The jobs created by this growing industry span the range of professional opportunities, from immediately available jobs that require no advanced education to those that utilize a PhD.
  
A wide range of non-solar businesses in Arizona are also benefitting from the clean energy economy. In towns, communities, and urban areas, solar is driving down company costs and saving businesses money. In rural areas, ranchers are utilizing solar to save on electricity costs, diversifying farm income and assisting with irrigation. And for families across the state, solar helps save money on home energy bills. Solar contributes not just to national energy independence – it helps small businesses and families with financial independence and stability.
  
Despite tremendous progress in states like Arizona, the United States is falling behind on efforts to meet critical climate goals. Arizonans can benefit from continued investments in the state’s solar energy economy, contributing towards meeting our nation’s climate goals while providing local jobs and reliable economic growth for our state. We strongly urge you to work towards the passage of a robust climate reconciliation package that includes a long-term extension of the solar ITC along with direct pay, to allow businesses to plan for a much larger clean energy buildout than is possible under current policy. We also ask for your continued support of a standalone energy storage credit to help the U.S. meet our energy needs and enhance the resilience of our electricity supply. Additionally, the manufacturing provisions in the legislation ensure that there will be a boom in domestic solar manufacturing.
  
We understand that as the Senate considers a reconciliation package, officials will weigh budgetary issues. The investment tax credit is fiscally prudent and contributes to rapid and needed economic growth. Not only does the ITC save money for families, businesses, and schools, it is an anchor that leverages further critical private sector investment.
  
We appreciate your support and look forward to hearing from you.
 
Sincerely,
Autumn Johnson
Executive Director
Arizona Solar Energy Industries Association (AriSEIA)
