Federal Renewable Programs
Residential & Corporate Renewable Tax Credit:
• Business and Residential tax credit of 30% of the total install cost of renewable system
(Systems to be less than 100 KW)
Qualifying Systems
Wind turbine
Geothermal Heat Pumps
Solar Systems
Solar – Water Heaters
Fuel Cells
REAP - USDA Grant/Loan Program:
• Agriculture and Small Rural Businesses can apply for 25% of total renewable projects cost
• 2010 REAP budget of $70 Million
Energy Efficiency Improvement:
• Residential Energy Efficiency Tax Credit – various amount depended on the improvement
• REAP – USDA Grant/Loan Program
Water heaters
Boilers

Building Improvements
State Renewable Programs
State Incentive:
Wind turbines < 40 KW qualify for net metering.
Purchasing utility basically by the power that goes back on the distribution grid at retail rate.
SWCE 2010 Buy Back Rates
Single Phase Units: $0.1161/kWh
Three Phase Units: $0.1107/kWh
State Sales Tax Exemption:
Wind and Solar systems materials are exempt from sales tax.
Includes materials used to manufacture, construct, maintain and repair renewable systems
State Property Tax Exemption:
Wind and Solar systems are exempt from property tax, (land the system is on is still taxable ).
However small production tax does exist if system is greater than 250 KW nameplate.
State Solar Rebate:
Unknown availability for 2010. Currently a waiting list for Federal Funds.
Costs and Benefits
In SWCE Territory – 39 KW Wind Turbine
Upfront Cost: (Turbine, Foundation, Labor etc)
Average Yearly Production: 44,000 kWh
Insurance and Maintenance
~$120,000
~ $ 4,115 per year
~ $ 750 per year
Photovoltaic System ( 2 KW System)*
Upfront Cost: (Panels, Inverter, Labor etc)
Projected Average Yearly Production: 3,000 kWh
Insurance and Maintenance
~$ 18,000
~ $ 315 per year
~ $ 100 per year
*Based on best information available – not SWCE numbers
Solar Calculator: Findsolar.com
Capacity factor for solar and wind is approximately 15%
Interconnecting a Wind or Solar System
to SWCE’s Grid
1) Fill out SWCE Application for Interconnection
$250 non-refundable application fee for systems
greater than 20 kW
2) Site Visit and Engineering Studies
On site meeting with system owner and electrician
3) Contracts Signed
4) Construction and Interconnection
SWCE personnel will perform necessary changes
to the distribution system and
metering for the wind or solar system.
5) Final Collection of Costs
Final billing of actual costs accrued by SWCE are
billed out less the deposit.
Contracts
Three Important Points
1) $300,000 in liability insurance per turbine – SWCE must have proof of insurance
2) Visible, accessible disconnect switch – SWCE has access to wind or solar system
3) Do No Harm Cause
Uniform Statewide Contract for Cogeneration and Small Power Production
Facilities Less than 40 kW
• Power Purchase Agreement
• Discusses methods of payment, program options, estimated deposit
and retail rate
Minnesota State Interconnection Agreement for Distribution Generation Contract
• Encompasses all types and sizes of distributed generation system
• Discusses fees, time periods, responsibilities and requirements
• Required by the State of Minnesota, created by the MN PUC
SWCE will assist our members with interconnecting
to the grid, but…
Concentrate on low cost energy efficiency methods first!
