Ridge Overview…
Regulatory & Environmental Benefits
MN Energy Act 2007 - Minnesota Power must provide renewable energy in proportion to retail electric sales:
12% by 2012
17% by 2016
20% by 2020
25% by 2025
Help Reduce MP’s Carbon (CO2) Footprint
Build & Expand Upon MP Core Competencies
MP has many of the necessary core competencies to own, maintain and operate the wind farms
Most viable option to achieve growth in renewable energy for MP.
MP will pursue other renewable options (Wind, Water, Wood)

Current Generation & Future Plans
Rising from the Ashes: Redeveloping the Prairie River Project
The Prairie River Project
•
A little project background…–
Prairie River Hydro•
Built in 1920 by Blandin
Paper Company•
Total capacity 1084 kW•
Operator’s residence –
upper level
•
MP Purchased in 1982•
Partially automated –
run from Thomson Hydro
•
Routine maintenance until 2008 when…

Fire destroyed the powerhouse
The Prairie River Project – Rebuild Study
•
Original Project Background ––
Selected HDR Engineering•
Study included 4 Options•
Option 1 –
Rebuild “like-kind”
no T1 work–
Only for insurance settlement negotiation•
Option 2 –
Rebuild same generation, least cost structure & crane including T1 overhaul
–
Additional generation with turbine efficiency improvements, approximately 10% more MWh
•
Option 3 –
Rebuild at most efficient generation for watershed–
Not practical –
licensing, reconstruction, lower generation
•
Option 4 –
Decommission/Sell–
Non-rate base, shareholder responsibility, negative public relations
•
Recommendation and Decision -–
Rebuild the facility•
“Least cost”
powerhouse with overhead crane•
Improved Safe Work Practices•
Overhaul Turbine 1•
Arc Flash Compliance•
Modern Equipment/Automation/PDM/Reliability•
Security Enhancements
–
Benefits•
Increased renewable generation over “as was”
condition•
Positive impact on shareholders, ratepayers maintain renewable energy diversity
•
Lower ongoing operational costs•
Positive public relations•
Construction jobs
