Distributed Generation Technologies See Continued Growth Globally

The world's installed capacity of decentralized energy by the end of last year was 281.9 GWe, the great proportion of which was cogeneration in industrial and district heating sectors that was fuelled by coal and gas and, to a lesser extent, biomass-based fuels

The share of global power generation from decentralized technologies has increased 0.2 percentage points in the past two years.

The level rose from 7% in 2002 to 7.2% in 2004, according to the latest annual ‘World Survey of Decentralized Energy' conducted by the World Alliance for Decentralized Energy. "The long-discussed and expected transition from a central power model to a hybrid DE-central mix may possibly be underway, though slowly," and it is optimistic that "this market share will continue to expand."

The report assesses recent progress in market growth for decentralized energy to assess key trends and market drivers, and to review developments in the world's markets. Between 2002 and 2004, 32.2 GWe of DE capacity was added, most of which was high-efficiency cogeneration. "Unlike the cogeneration market, PV industry growth rates remain very high during the period."


The forecast consumption of coal, nuclear and renewables have been increased from earlier predictions, while petroleum and natural gas consumption are lower.

The United States accounts for 2,544 MW of total installed capacity and 1,914 MW of operation, and the difference is due to a lack of steam due to over-exploitation of the Geysers field in California.
