51st State goes live with new visions for energy system change

Beyond coming up with visions for a 21st-century energy system from the ground up -- as if for a new state with no regulations or market structures -- the biggest challenge for groups and individuals submitting concepts for the Solar Electric Power Association's 51st State Initiative may have been getting out of their own frames of reference. Readers will now be able to judge how well they did as all papers received meeting the initiative guidelines are posted on the 51st State website.

Utility-scale solar in 2014: Unpredictable, diverse and counting down to ITC sunset

2014 was utility-scale solar’s most successful year ever, with 115 projects of 5 megawatts (MW) or more completed for a total of 3,550 MW. It was also the year when utility-scale solar stopped being predictable as the market's underlying geographic, system capacity and policy trends underwent some noticeable changes.

Multiple strategies needed to cut solar interconnection times

When utility customers decide to go solar, the question frequently uppermost in their minds is -- “How long will it take before my system is up and running?" The National Renewable Energy Laboratory, along with the Solar Electric Power Association and other organizations, have launched the Distributed Generation Interconnection Collaborative to help the solar industry cut interconnection time and costs.

Arizona's utility-owned solar programs: New price models, grid integration and collaboration

While left off most year-end reviews, the approval of programs that will put two Arizona utilities in the rooftop solar business could be 2014's watershed event. Rather than the potential setback for solar some advocates and installers fear, the programs that Arizona Public Service and Tucson Electric Power will launch this year could be a pivotal step toward much-needed new pricing models and technology for integrating more renewables onto the grid.

Audi, APS and utilities' role in getting more solar on the grid

If anyone still doubts the inevitability of solar power’s integration into the United States’ power supply, the Aug. 5 announcement of Audi’s plans to partner with SunPower to provide clean power for the German automaker’s new plug-in hybrid provides strong, evidence, if not all the proof needed.
