• MGE’s gets its power from two sources– Local generation– Transmission lines which bring power
from other non-local generating sources

• MGE’s power is supplied from a variety of sources, including:
GAS/OIL 4%
RENEWABLE 2%
PURCHASED POWER
38%
COAL 56%
Four Planning Realities
1. The mix we select between generation and transmission affects reliability and cost.
Four Planning Realities
2. The mix of fuel sources we select affects reliability and cost.
Four Planning Realities
3. The mix we select must allow MGE to comply with stringent regulatory requirements.
Four Planning Realities
4. There are technological and operational limits we can reasonably expect from increasing alternative sources and/or conservation.
Demonstration of Planning Realities
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.
