  1. Where we are… Kilowatt Hour Usage 1997-2002 2260 MKWH (Business) MGE serves approximately 113,000 residential customers in the Dane County area 10% …and approximately 17,500 business customers. 839 MKWH (Residential) 16.4%

  2. Where we are… • In addition to more people and more businesses providing more jobs, we also have to deal with increased usage • Computers • Computer systems • Air conditioning • Electronics/Appliances • Larger homes

  3. AND, will need to address increased usage Where we are… Kilowatt Hour Usage 1997-2010 By 2010, MGE estimates that we will be serving nearly 130,000 residential customers. 2781 MKWH (1997) 3098 MKWH (2002) 3616 MKWH (2010) Total Usage …and approximately 20,000 business customers in the Dane County area.

  4. Where we are… Kilowatt Hour Usage 1997-2010 These forecasts take into account energy efficiency and conservation efforts. 3015 MKWH (1997) 2781 MKWH (1997) 3466 MKWH (2002) 3098 MKWH (2002) 4376 MKWH (2010) 3616 MKWH (2010) Total Usage Forecasted usage without energy efficiency and conservation efforts.

  5. MGE’s gets its power from two sources Local generation Transmission lines which bring power from other non-local generating sources 15% 85% Where we are…

  6. PURCHASED POWER 38% GAS/OIL 4% COAL RENEWABLE 56% 2% Where we are… • MGE’s power is supplied from a variety of sources, including:

  7. Four Planning Realities • The mix we select between generation and transmission affects reliability and cost.

  8. Four Planning Realities • The mix of fuel sources we select affects reliability and cost.

  9. Four Planning Realities • The mix we select must allow MGE to comply with stringent regulatory requirements.

  10. Four Planning Realities • There are technological and operational limits we can reasonably expect from increasing alternative sources and/or conservation.

  11. Demonstration of Planning Realities Energy Model

  12. The Energy ED Simulator • Objective • Develop a way to teach people about the trade-offs and complexities of ensuring that we have enough electricity to keep up with growing demand. • Developers • The University of Wisconsin’s College of Engineering & We The People in the Fall of 2001 • Uses to Date • We The People “Powering Wisconsin” Energy Conference • “Powering Iowa” town hall meetings
