Economic Calculations
These are a series of pages and spreadsheets from our work calculating a fair and equitable payment for wind, solar, and other renewables. Most of this work was done more than a decade ago and though the principles remain the same, the prices have changed dramatically–for the better. It’s interesting to note that prices paid for German solar feed-in tariffs in 2023 were competitive with prices in SREC trading programs in the USA.
The Art of Advanced Renewable Tariffs Systems (ARTs) Design: Some Lessons from Past and Ongoing Experiences

Bernard Chabot
International energy policy consultant Bernard Chabot’s detailed briefing on how to define a targeted fair and sufficiently attractive profitability for investors through Feed-in Tariffs using the Profitability Index Method (PIM).
Economics of Photoelectricity Open Source Spreadsheet
By
Paul Gipe
This is an open source spreadsheet on the economics of solar photovoltaics. The spreadsheet contains more than 50 individual tabs covering a multitude of topics beyond the expected cash flow model. The spreadsheet includes sixteen tables of statistics on the installation of renewable energy technologies worldwide. There are more than a dozen tables of feed-in tariffs in countries around the world.
Advanced Renewable Tariffs Pricing Worksheets
By
Paul Gipe
The following worksheets were developed for the Ontario Sustainable Energy Association and the Toronto Renewable Energy Cooperative in 2007 for the report Renewables without Limits: Moving Toward Advanced Renewable Tariffs. These tables have multiple tabs. For an explanation of each tab, see the OSEA report. Note that the assumptions used in the worksheets and the worksheets themselves evolve.

Fair and Efficient Rates for Large Scale Development of Wind Power: the New French Solution
By
Bernard Chabot and Bernard Saulnier
A new electricity rate system for wind energy has been published on June 8th 2001 in France. The European and the French context that led to the decision to develop wind energy in France through this new rate system are presented. In order to achieve a minimal goal of 5 to 10 GW of wind capacity installed in 2010 (instead of 70 MW in operation at the end of 2000), the French system is designed to attract private investors by providing a minimum profitability for projects on medium quality sites while avoiding undue profitability for best quality sites.
