Solar Gardens: A Fast-Growing Approach to Photovoltaic Power

Power Magazine, May 2015, by Kennedy Maize.

"How to give electricity customers who can’t take advantage of rooftop solar access to the sun? Community solar—a shared resource—is a fast-growing segment of the renewable energy market, making solar photovoltaic power more accessible while offering another approach to distributed generation."

Distributed Power’s Rising Importance for U.S. Electrical Infrastructure

Power Magazine, May 2015, by Devon Manz and others.

"Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase."

NREL Report Estimates Market Potential of Shared Solar and Discusses Relevant Securities Regulations

NREL News Release, Apr. 27, 2015.
http://www.nrel.gov/news/press/2015/16496.html

"Analysis from the Energy Department's National Renewable Energy Laboratory (NREL) finds that by making shared solar programs available to households and businesses that currently cannot host on-site photovoltaic (PV) systems shared solar could represent 32 to 49 percent of the distributed photovoltaic market in 2020."

Centralized & Decentralized PV Power Plants: Vendor Perspectives

"As the capacity of utility-scale PV plants has increased in the US, so has the capacity of the centralized power-conditioning units used in these projects. Today, many plants utilize factory-integrated skids that combine inverters, medium-voltage transformers and switchgear into packages that range in capacity from 1 MW to 2.5 MW. These integrated systems offer project developers many advantages, including optimized component compatibility, as well as reduced installation time and expense."

"Ashley Brown, executive director of the Harvard Electricity Policy Group, argues that rooftop solar is valuable, but should not be paid at full retail value."

CA Clean Energy Loan Program Grew 10 Times Bigger in 2014

Utility Dive, Dec. 17, 2014, by Herman K. Trabish.
http://www.utilitydive.com/news/ca-clean-energy-loan-program-grew-10-times-bigger-in-2014/345321/

"California’s programs to fund energy efficiency retrofits and distributed generation installations for homes and businesses backed about $600 million in projects in 2014, up from about $60 million in 2013, Greentech Media reports. About 75% of the funding went to energy efficiency and 25% to distributed generation."

Utilities Face Significant Revenue Losses from Growth of Solar, Storage and Energy Efficiency, Accenture Research Shows

Accenture News Release, Dec. 8, 2014.
http://newsroom.accenture.com/news/utilities-face-significant-revenue-losses-from-growth-of-solar-storage-and-energy-efficiency-accenture-research-shows.htm

"Continued growth of distributed energy resources and energy efficiency measures could cause significant demand disruption and drive down utilities’ revenues by up to $48 billion a year in the United States and €61 billion a year in Europe by 2025, according to Accenture’s Digitally Enabled Grid research."

The Fight Over Solar Moves from Net Metering to Rate Design

Utility Dive, Nov. 3, 2014, by Herman K. Trabish.
http://www.utilitydive.com/news/the-fight-over-solar-moves-from-net-metering-to-rate-design/327742/

"Fights over electricity rates are brewing all across the country. Utilities say new rate proposals will protect customers who haven’t moved to solar and energy efficiency. But those who have moved say the proposals only protect utilities." "There are two categories of rate restructuring and rate design changes bubbling up,” explained Environmental Law & Policy Center Sr. Attorney Brad Klein. “The first is to move cost recovery from the variable per-kilowatt-hour charge and increase the monthly fixed charge. The other is to impose a monthly dollars-per-kilowatt charge on owners of distributed generation.”

Preparing for Distributed Generation in the Northwest

Northwest Public Power Association (NWPPA) Bulletin, Oct. 2014, by Charlie Black. (open PDF, then scroll or jump to page 26)
http://www.nwppa.org/External/WCPages/WCWebContent/WebContentPage.aspx?ContentID=1928

"In recent years, electric utility customers have begun showing greater interest in distributed generation. Declining costs and expanding availability of on-site electric generating systems, such as roof-mounted solar photovoltaic equipment marketed and installed by third-party service providers, are causing residential and business customers to consider self-supply as an attractive alternative to relying exclusively on centrally generated power delivered via the utility grid."
