Renewable Portfolio and Future Plans
Topics:
2
What drives the renewable plan
Renewable resources
We Energies’ large wind projects
Wind power: on-shore vs. off-shore
Biomass – 50MW Rothschild project
Solar power
Questions
Why is We Energies Building
Renewable Generation?
Customer demand for renewable energy products –
Energy For Tomorrow
Wisconsin Renewable Portfolio Standard (RPS)
3
2010 Requirement – 4.27%
2015 Requirement – 8.27%
Equivalent to approximately 900MW of wind
What technologies have been used and
what’s next – wind, solar, biomass?

Characteristics of Wind Power
Blade tip height - 400’ – 500’
Blade length – 135’ – 165’
Each turbine powers approx.
450 homes
Can be constructed in less
than 1 year
Minimal intrusion on
agricultural land use
Constructed on operating
farms owned by others

Glacier Hills Wind Park
Elements of a Good Wind Project
7
High elevation – good wind resource
Low population density
Close proximity to high voltage transmission lines
Maintain distances from homes, schools, churches
– occupied buildings
Maintain distances from roads, power lines, other
infrastructure
Support from landowners and community
Wind Power: On-shore or Off-shore?
8
On-shore
Moderate wind resource
Closer to people
Reasonable cost to construct
Relatively easy to maintain
Proximity to electric transmission
Off-shore
Very good wind resource
Greater distance to people
Very expensive to construct (floating foundations) and operate
Problems with ice and icing
Distant to electrical transmission system

Biomass Project
11
Domtar Rothschild Paper Mill (near Wausau)
$255 million capital cost
50MW, cogeneration
100% of Domtar’s steam needs
Higher capacity factor compares to 150MW of wind
generation
Permitting in 2010, scheduled completion 2013
Biomass Fuel
12
Fuel is 500,000 tons per year of waste wood from
existing forestry operations
Typically tree tops, bark, and branches
Fuel is chipped off site and delivered in enclosed
trucks
Domtar currently uses 130,000 tons per year for
biomass steam
Biomass Project Advantages
Net results 30% decrease in boiler emissions from
the site
13
Shut down older, less efficient boilers
Job creation and support
460 direct jobs at Domtar site
400 jobs in construction of the facility
150 jobs in forestry and fuel supply
Built on existing Domtar plant footprint
Solar Power
14
We Energies committed to proposing approximately
13 MW of solar
Currently evaluating technologies and integration
with distribution system
Solar panel prices have come down considerably
over the last 2 years
While more expensive than wind generation, much
better correlation with demand cycle
What’s Next?
In addition to biomass and solar, We
Energies will need to build an estimated 3
to 4 more wind projects to comply with
current renewable requirements
– or find technology alternatives
