IGCC - Clean Coal Study Group
 Integrated Gasification Combined Cycle Technology
As part of the Conserve Wisconsin agenda,
 (4252 kb),
Governor Doyle asked the Public Service Commission (PSC) and the Department of Natural Resources (DNR) to
investigate Integrated Gasification Combined Cycle (IGCC) technology and its potential for the future of
Wisconsin.
IGCC converts coal into gas. The gas is cleaned and then burned in a combined cycle gas turbine power plant.
IGCC dramatically reduces air emissions, water use and industrial waste, but there are unanswered questions about
the technology’s reliability and cost.
Development of Clean Coal Study Group
The Clean Coal Study Group was created to analyze the technology and answer questions about reliability and cost. PSC
Commissioner Mark Meyer and DNR Air and Waste Administrator Al Shea lead the effort. Study group members include environmental
organizations, customer and labor groups, research institutions, electricity providers and the general public. The
Clean Coal Study Group’s objective is to identify the feasibility and suitability of IGCC technology for Wisconsin.
Final Report
Integrated Gasification Combined- Cycle Technology Final Report (7686 kb)
The Integrated Gasification Combined- Cycle Technology Final Report
(7686 kb) provides a
cost and benefit analysis of IGCC technology. It shows that if Congress enacts legislation limiting carbon dioxide
emissions from power plants, the cost of electricity generated from an IGCC power plant is competitive with the
cost of electricity produced from conventional coal-fired power plants. Carbon dioxide is the primary greenhouse
gas and is emitted mainly from power plants and automobiles. Development of the report was conducted jointly by the
DNR and PSC in consultation with a study group of experts representing environmental groups, consumer groups, industry,
labor and utilities.
The Clean Coal Study Group met October 2005 to April 2006. Meetings
were open to the public.
