NREL and Partners Review Key Issues, Lessons Learned from U.S. Wind Integration Studies and Operating Practices
As a complement to DOE's recently released Wind Vision Report, a new paper summarizes the lessons learned from actual power systems operational practice, along with some of the most relevant and comprehensive wind integration studies conducted during the past several years.

The Solar Access to Public Capital (SAPC) working group has released new best practices guidelines for solar photovoltaic (PV) systems, with the goal of increasing investor confidence in the long-term viability of PV systems. The guides — SAPC Best Practices in PV System Installation and SAPC Best Practices in PV Operations and Maintenance — were developed by SAPC subcommittees, each involving dozens of solar and finance entities.

The Energy Department’s (DOE) National Renewable Energy Laboratory (NREL) has used the Battery Lifetime Analysis and Simulation Tool (BLAST) to confirm that energy storage for demand-charge management can deliver attractive economic benefits. The analysis paired recent utility rate structures with historic data on solar photovoltaic electricity generation and commercial facility loads to evaluate 6,860 unique scenarios. The results revealed that, in the absence of incentives, small battery systems reducing peak demand by 2.5 percent offer the most attractive return on investment.

The Energy Department's National Renewable Energy Laboratory (NREL) has gathered and analyzed data for more than 30,000 solar photovoltaic (PV) installations across the United States to better understand how interconnection regulations align with actual project completion timelines. The findings indicate that interconnection process delays are common, and can range from several days to months. Streamlining the application review and final authorization processes can ultimately benefit utilities and solar consumers by reducing the time and cost associated with going solar.

The Energy Department’s National Renewable Energy Laboratory (NREL) and the Electric Power Research Institute (EPRI) have launched the Clean Energy Incubator Network. The program, funded by the Energy Department, aims to improve the performance of clean energy business incubators, connect critical industry and energy sector partners, and advance clean energy technologies emerging from universities and federal laboratories.

Two new reports from the Energy Department's National Renewable Energy Laboratory (NREL) examine the economic options customers face when deciding how to finance commercial or residential solar energy systems. NREL analysts found that businesses that use low-cost financing to purchase a photovoltaic (PV) system and homeowners who use solar-specific loans can save up to 30 percent compared with consumers who lease a PV system through a conventional third-party owner.

The newly released 2013 Renewable Energy Data Book illustrates United States and global energy statistics, including renewable electricity generation, renewable energy development, clean energy investments, and technology-specific data and trends. The Data Book is produced and published annually by the National Renewable Energy Laboratory (NREL) on behalf of the Energy Department’s Office of Energy Efficiency and Renewable Energy.
