Solar Real-Time Pricing: Is Real-Time Electriciy Pricing Beneficial to Solar PV in New York City?

The goal of this study is to evaluate the validity of the following statement: “the coincidence of high electric energy prices and peak solar electric photovoltaic (PV) output can improve the economics of PV installations, and can also facilitate the wider use of hourly pricing.” The study is focused on Con Edison electric service territory in New York City.

State Clean Energy Policies Analysis (SCEPA): An Analysis of Renewable Energy Feed-in Tariffs in the United States

This report defines a FIT policy, explores U.S. FIT policy design, and highlights a few of the best practices in FIT policy design. It also explores how FITs can be used to target state policy goals and examines policy interactions with other renewable energy policies. An overview of FIT impacts (jobs and economic development) in Europe is included.

Solar PV Project Financing: Regulatory and Legislative Challenges for Third-Party PPA System Owners

This paper summarizes five common regulatory challenges for third party PPA financing, when they occur, and how they have been addressed in five states. This paper also presents alternative to the third-party ownership PPA finance model, including solar leases, contractual intermediaries, standardized contract language, federal investment tax credits, clean renewable energy bonds, and waived monopoly powers.

State Clean Energy Policies Analysis: State, Utility, and Municipal Loan Programs

This report relies on six in-depth interviews with loan program administrators to provide descriptions of existing programs. Findings from the interviews are combined with a review of relevant literature to elicit best practices and lessons learned from existing loan programs. Data collected from each of the loan programs profiled are used to quantify the impacts of these specific loan programs on the commonly cited, overarching state clean energy goals of energy security, economic development, and environmental protection.

Trends in Utility Green Pricing Programs (2005)

This report presents year-end 2005 data on utility green pricing programs, and examines trends in consumer response and program implementation over time. The data in this report, which were obtained via a questionnaire distributed to utility green pricing program managers, can be used by utilities to benchmark the success of their green power programs. It is important to note that this report covers only a portion of voluntary markets for renewable energy.

Photovoltaic Systems Interconnected onto Secondary Network Distribution Systems – Success Stories

This report examines six case studies of photovoltaic (PV) systems integrated into secondary network systems. The six PV systems were chosen for evaluation because they are interconnected to secondary network systems located in four major Solar America Cities.

Green Power Marketing in the United States: A Status Report (11th Edition)

This report documents green power marketing activities and trends in the United States, focusing on consumer decisions to purchase electricity supplied from renewable energy sources.

Utility-Interconnected Photovoltaic Systems: Evaluating the Rationale for the Utility-Accessible External Disconnect Switch

This report examines the utility-accessible external disconnect switch debate in the context of utility-interactive PV systems for residential and small commercial PV installations. It focuses on safety, reliability, and cost implications of requiring an external disconnect switch.
