Efficient Power Generation Dick Munson Recycled Energy Development Midwest Media Project 10 July 2007
2
Why Consider Alternatives? Average plant built with 1950’s technology Only 33% efficiency; burn three units of fuel to obtain one unit of electricity
3
Conventional Central Generation Fuel 100% 33% delivered electricity Power Plant T&D and Transformers Pollution 67% Total Waste Line Losses 9-20%
4
Why Consider Alternatives? Average plant built with 1950’s technology Only 33% efficiency; burn three “lumps” of fuel to obtain one “lump” of electricity Electric generators are largest polluters Unreliable supplies cost $150 billion/yr U.S. consumer loses power 214 min/yr; 70 min/yr in UK; 6 min/yr in Japan
5
Rising Prices Focus One’s Attention Fuel costs are 3-5 times above 1990 levels, and long- term contracts now below the spot market. Clean Air Interstate Regulations (CAIR) and Clean Air Mercury Regulations will add $550-850/kw for existing plants New coal plant costs $2,500/kw, up from $800/kw in the late 1990s Pending costs: transmission expansion, greenhouse- gas reductions (carbon credits of $20/ton would add 2 cents/kwh). Midwest’s electricity prices could double in 5-10 years.
6
U.S. Electric Industry Fuel- Conversion Efficiency
7
Combined Heat and Power (CHP) Fuel 100% Steam Electricity Chilled Water 90% 10% Waste Heat, no T&D loss Pollution (At or near thermal users) CHP Plants
8
Local Generation Plants we have built that recycle waste heat Denmark Electric Efficiency
9
U.S. is an International Laggard in Capturing Heat and Power Feasible Target of 30% CHP in US
10
Denmark Changed in Two Decades Source: Danish Energy Center
11
Best New Generation: Recycle Industrial Energy Wasted energy streams in nineteen industries could generate 19% of US electricity Source:USEPA 2004 Study Recycled Energy in the US Identified Opportunities 95,000 MW Recycled Energy in Service 9,900 MW
12
Recycled Energy (At user sites) Waste Energy 100% 10% Waste Heat Steam Generator 65% Steam 25% Electricity Back-pressure Turbine Generator No Added Pollution
13
Industrial Energy Recycling 90 MW Recycled from Coke Production
14
Policy Options Remove policy barriers – interconnection standards, backup power rates, private wires. Recognize the value of Clean Distributed Generation’s Benefits – less T&D, reduced line losses, grid stability. Ontario Standard Offer, Subtitle E in House Energy bill. Induce Efficient Biofuel Production
