2009 Reports

Photovoltaic Incentive Programs Survey: Residential Participant Demographics, Motivations and Experiences - Nov 2009
In coordination with SEPA, an electronic survey was developed and distributed by U.S. utility and state PV incentive program managers to consumers who installed PV systems and received a rebate to offset the cost. The survey asked about the participants' satisfaction and experiences with the installation, incentive, interconnection, and ongoing maintenance of their systems. The resulting report analyzed the data across geographies to draw distinctions and parallels across the country. Download Report. 

Top Ten Utility Solar Integration Rankings - May 2009
Each year, SEPA conducts a nationwide survey of utilities to find out how much solar electricity was integrated into their service territories both annually and cumulatively. The resulting report crowns the most solar integrated utilities in the United States and discusses the large scale solar projects being planned for the future.  Download Report.

Distributed Photovoltaic Generation for Regulated Utilities - Feb 2009
This analysis looks at both the regulatory and practical issues surrounding the installation and ownership of distributed generation photovoltaic systems by electric  utilities, including an overview of the regulatory process, the standards utilities must demonstrate to regulatory for approval and various configurations of utility ownership.  Download Report.

Decoupling Utility Profits from Sales: Issues for the Photovoltaic Industry - Feb 2009
The reduced sale of electricity creates an inherent problem for electric utilities in maintaining long-term operating revenue, especially as the solar industry expands.  Decoupling is a regulatory policy option that can change the way utilities recover revenues to adjust this disincentive.  This decoupling white paper introduces the concept into the solar community, explaining what decoupling is, and defining the different types. It includes a case study showing how solar market development in the future might affect utility rates under decoupling.  Download Report.

Utility Solar Tax Manual - Jan 2009
In 2008, Congress extended the federal solar investment tax credit for eight years and removed the utility exemption, allowing regulated investor-owned utilities to utilize the credit. This manual provides detailed explanations of the tax provisions related to the bill, as well as exploring other tax issues such as Clean Renewable Energy Bonds, and unique business tax structures and issues.  Members: Download Report.  Non-Members: Download Preview (Purchase Report).


Utility Solar Procurement Study - Jan 2009
This report identified best practices for traditional utility solar procurement (RFPs/PPAs) and innovative new acquisition methods that may present cost or efficiency solutions for both utilities and the solar industry.  Download Report.

 

 2008 Reports

  Special Report: Electric Utilities and Solar, A Market Review
In the last year, U.S. electric utilities' engagement with grid-connected solar electricity has increased significantly, with major photovoltaic (PV) and concentrating solar thermal (CST) announcements by utilities, their customers, and third-party solar developers. This executive review of utility activity, rankings and future announcements provides a concise summary of current and future utility solar activities.  Download Report.

2007 Top Ten Utility Solar Integration Rankings
In early 2008, SEPA conducted a nationwide survey of utilities to find out how much solar electricity, e.g. PV and CST, was integrated into their service territories through the end of 2007. The resulting report, which will be released annually, crowns the most solar integrated utilities in the United States and discusses future solar market development issues that have arisen recently.  Download Report.

Fact Finding Mission to Germany for Utility Decision Makers
Thirty-five US utility decision makers traveled with SEPA to Germany in June 2008 to examine how they can emulate the success of German utilities in integrating large quantities of solar electricity into a national utility grid without creating transmission bottle necks, system quality distortions, and scheduling issues. This report summarizes the findings for other US utilities.  Download Report.

Utility Solar Business Models *Access to USBM Project: Click Here
While renewable market requirements are driving solar investment currently, business opportunities are beginning to emerge for utilities to become involved in the solar value chain. This report highlights emerging utility business models that provide value-added solutions for utilities, customers, and the solar industry.  Download ReportDownload Executive Summary.

Photovoltaic Capacity Valuation Methods
This report catalogues the statistical methods used to measure the relationship between peak electricity and solar PV output, compares all the methods in three case studies for three electric utilities, and documents the results from a 2007 workshop on the topic with utilities, industry, and other stakeholders.  Download Report.

Residential Photovoltaic Metering and Interconnection Study
Utilizing data from a survey of 63 U.S. utilities, this report establishes a baseline of utility practices related to residential grid-connected solar photovoltaic metering and interconnection practices.  Download Report.

Photovoltaic Asset Ownership Analysis - Early 2010
EuropeGrid-connected distributed photovoltaic ownership has diversified over time, from customer to third-party to utility, with each successive ownership model expanding the solar market opportunities significantly.  However, these new business models change the costs and benefits to each stakeholders in distinct ways.   This study will look at the various PV ownership models and identify the changing issues that each stakeholder perceives as the PV market evolves into a more complex business landscape.

Photovoltaic Technology Characterization - Early 2010
There are at least seven commercial photovoltaic panel technologies currently available in the market. This study will be a qualitative and quantitative comparison of photovoltaic technology types based on their technological characteristics, primary market uses, environmental profiles and other relevant components that define these traditional and emerging solar generation types.

Utility Solar Business Models: Phase 2 - Early 2010 *Access to USBM Project: Click Here
While renewable market requirements are driving current solar investment, business opportunities are emerging for utilities to become involved in the solar value chain. This report will highlight utility solar business models that are providing value-added solutions for utilities, customers, and the solar industry.
