SaskPower’s Challenge• Unprecedented demand for power
• Strong provincial economy
• Industry is approximately 50 per cent of total load
• Last 10 years, demand has been 1.8 per cent per year
• Next 10 years forecast at 2.4 per cent growth per year.
• $5B asset value company; 80 years old• Spending $15B in the next 10 years- aging
infrastructure
• Provincial environmental legislation has yet to be released;
• Alignment with Federal government coal phase out plans
3
SaskPower Distributed Generation Programs
Net Metering Program (up to 100 kW)• Typically rural and urban residential customers
Small Power Producers Program (up to 100 kW)• Small commercial Independent Power Producers (IPP)
Green Options Partners Program (>100 kW to 10 MW)• Small commercial to large commercial IPP
Benefits of DG• Capital offset• Less line losses• Environmental benefits• Job creation• Empowering customers
4
Preferred Environmental Technologies
• Technologies permitted for all programs:
• Micro-hydro• Small wind turbines• Solar photo voltaic (PV)• Biomass fuels (gas, liquids and solids)• Flare gas• Waste heat/Heat recovery technologies
• SaskPower owns environmental credits associated with power generation
5
Net Metering Program
Up to 100 kW
– Started in 2007; 230 customers; 85 per cent small wind; 15 per cent solar PV
– Primary purpose is to offset your consumption
– Bank credits for your excess power delivered
• Credit at customer retail rate
• Credit will be taken off next month’s bill
• After 12 months the credits are forfeited
– Two-year contract
– Making some improvements to this program in 2011
6
Small Power Producers ProgramUp to 100 kW:
– Started in 1994, currently five participants
• (one Combined Heat and Power, four Wind)
– Two options:
• Sell all power
• Sell excess power
– 2011 price SaskPower will pay is $0.09609/kWh escalating two per cent /year for a 20-year contract
7
Green Options Partners Program
7
>100 kW and 10 MW
• Program cap of 50 MW in 2011
– No more than 25 MW can be made of wind
– A lottery to select applications for the 2011 program closes June 1
• The 2011 program’s payment rate is $96.09/MWh for projects that reach commercial operation in 2011
• Rate escalates at 2 per cent per annum for the duration of the 20-year contract. 40 year contract for hydro projects.
• GO Partners Program reviewed annually

Net Metering Rebate Program
• 35 per cent rebate to total installed cost (max of $35,000 rebate):• 35 per cent total = 10 per cent SaskPower and 25 per cent Go Green
Fund
• Program led by Ministry of Environment’s Go Green Fund• Rebate program ended March 31, 2011
• Go Green Fund is finalizing outstanding rebates to customers that committed to projects by end date
• Public and industry pressure on Ministry to offer a bridge financing program until a new program is in place
• Decisions will be made in the upcoming weeks (months?)
11
Renewable Energy Incentive Program Development
New REI Program• Saskatchewan Ministry of Environment issued an RFP (December
2010)• Consultant to help develop and design a new REI program
• Awarded to Dunsky Energy Consulting (Montreal)-end of February 2011, and work began in March 2011
• Program design work should be completed by September 2011
• This is a new program, not policy change
• Implementation plans TBD
12
REI Program FundingValue Propositions• Funding agencies being solicited
• Ministry of Environment- Go Green Fund- $/tGHG avoided• Net Metering Rebate $200/tCO2; Clean Coal $80/tCO2
• Enterprise Saskatchewan- Job creation; $/Jobs
• Saskatchewan Innovation- Technology development
• SaskPower- Supply value- $/MWh and/or $/MW
• Ministry of Energy and Resources- Supply value-$/MWh and/or $/MW
13
Renewable Energy Incentive Program Development
New REI Program Considerations:• Quality- Industry standard (CanSIA, CanWEA,SWCC) and CSA
certification for product, product performance and installation
• Financing- Mechanisms for accessing capital
• Incentives- Production (by kWh); capital costs; combination of both; possibly up to 500kW; possible variations by technology type
• Implementation- Interconnection processes and contracts

Distributed Generation Programs – Why?
• Capital investment offset: Customers purchase, install, and operate renewable power generation equipment
• Energy produced closer to where it is consumed: Less line losses equals less energy produced at power plant
• Offsets some central power generation: Time of day; types of generation at various times in the day
– Winter peaking utility; 7:00 pm November-February
• Clean, green and local: Develops green industry, creates local jobs – Distribution, sales, installation (electrical contractors)
• Empowering our customers to choose the source of their electricity
