• Good for the Environment• Reduces CO2 Emissions by 5,000 metric tons• Equivalent to planting 750 trees or taking 750 cars off the road

• Good for the Economy• Local generation creates local construction jobs

• Good for United Power• Cost of Energy is predictable and stable• Helps meet RPS requirements• Net benefit to all co-op members

Renewable Generation & RPS

• Continue to develop projects that benefit overall membership

• Enhances community presence and co-op reputation

• Provides hedge against rising energy prices

• Needed to meet higher RPS requirements

• Working with Tri-State to develop these small DG projects
