BACKGROUND
• IEUA has been considering the benefits of providing clean and renewable energy with potentially more valuable green attributes which IEUA can use to offset other high-Carbon emitting operation.
• IEUA analyzed the technical feasibility of utilizing on site power generation systems for the following reasons:
1) Low cost per kilowatt hour
2) Environmentally friendly
3) Reliability with minimal maintenance.

Goals & Objectives
• IEUA’s goal is to maximize renewable energy, optimize
energy usage and become gridless by 2020
• Electric demand is approximately 8 MW avg.(12 MW
peak)
• Renewable Energy includes:
• Solar Power (completed)
• Wind Power
• Fuel cells
• IEUA executed Power Purchase Agreements (PPA) for
receiving three renewable energy sources.

![Page 8: SCAP ENERGY MANAGEMENT COMMITTEEscap1.org/POTW Reference Library/110428 IEUA wind power ppt.pdf · scap energy management committee renewable energy sources: wind power presented](https://reader034.fdocuments.in/reader034/viewer/2022042521/5f6beae798a06723ff59f10b/html5/thumbnails/8.jpg)
No development cost
No capital investment
No maintenance cost
Stable and predictable power cost
Over 1. 5 million kWh generated annually with zero air emissions
Will displace 6,125,000 lbs of carbon = to planting 8,624 trees or removing 528 cars from the road
Wind turbine is a visible symbol of environmental stewardship
Power generated will be supplied to RP-4 and IERCF with the ability to control the amount of power to be provided to each facility (SEPARATE METERS)
Small footprint compared to solar
Minimal IEUA / IERCA
Expense

PPA Base Model – Reduces Costs Zero Payback Period
• All upfront and ongoing expenses paid by Provider • Minimal costs incurred by the customers during permitting, design and construction. • Project returns positive cumulative cash flow on Day One
Significant Cumulative Savings
• SCE prices increases historically, escalate at 5%-6% annually • Customers may save millions of dollars in energy costs
![Page 12: SCAP ENERGY MANAGEMENT COMMITTEEscap1.org/POTW Reference Library/110428 IEUA wind power ppt.pdf · scap energy management committee renewable energy sources: wind power presented](https://reader034.fdocuments.in/reader034/viewer/2022042521/5f6beae798a06723ff59f10b/html5/thumbnails/12.jpg)
Q: What expenses will the customer incur?
A: Minimal expenses to coordinate the planning, design and construction. May
have some internal legal or closing costs. Customer leases ~ 50 sq. ft. parcel
for $1 per year over the 20 year project life. Turbines are delivered, installed,
and commissioned at Provider’s expense.
Q: Who pays repair, maintenance, and operational costs?
A: Provider pays all costs associated with operating and maintaining the
turbines for the full project lifetime.
Q: How does IEUA (customer)save money?
A: All the wind power is sold to the customer at a discount to their utility rates.
This results in an energy charge savings, and in some cases demand charge
savings too.
Q: What happens at the end of the 20 year project life?
A: Provider will extend the power purchase arrangement or “re-power” with the
best available technology. The customer may also purchase the facility at the
then fair market value.
