5. Massachusetts: A Good Solar Market MA = among the most expensive energy prices in the United States ~40% MA electricity = fueled by volatile natural gas MA solar capacity factors = 13-15% (~ 75% of CA solar yield) Mass. Maritime Academy PV Arrays, Bourne, Massachusetts 5

7. Basic Solar Site Needs • Site Requirements: Flat (<5% grade), south-facing, un-shaded & close to grid • Size: 2MW system requires 12-14 acres of land (depending on shading and grading) • Security: Fencing and other appropriate security measures needed 7 7

8. Solar Value Proposition I. No Capital Costs to Our Customers - Instead, customers enter a long-term power purchase agreement II. Valuable Peak Power Generated - Peak power can cost utilities 300% or more compared to non-peak hours - Daylight Hours = 56.7% of 500 most expensive peak energy hours each year (Source: NE-ISO day-ahead spot market electricity prices, 2005-09) - Distributed solar facilities save municipal power customers expensive and fast-rising peak energy costs (forward capacity and regional transmission) III. Transmission Loss Avoidance Distributed solar facilities suffer minimal transmission loss, compared to 10% loss factors for energy delivered via NE-ISO regional grid 8

9. Solar Value Proposition (continued) IV. Solar Hedges Volatile Gas-Fueled Electricity Prices Over 25-30 year life, a solar facility provides predictable energy rates and eliminates exposure to natural gas-fired electricity prices, which are likely to rise in response to geopolitical events and shifts in gas demand/supply 9

10. Powerful Federal Incentive: 30% ITC Grant Overview:   2009 American Recovery Act converted Investment Tax Credit (ITC) into a cash grant equal to 30% of project costs paid to owners of newly installed, U.S.-sited renewable energy facilities Eligibility:  Grant may be paid to any U.S. taxpayer owner, including LLC or other pass-through entity (provided no government or nonprofit partners) Deadline: “Significant construction” required by Dec. 31, 2010: defined by U.S. Treasury as at least 5% of project cost expended & non-refundable. Grant Payment: 30% project cost paid in cash by U.S. Treasury within 60 days of electric service 10

11. Powerful State Incentive: MA Solar-RECs Overview:  MA DOER authorizes 400MW of solar facilities to sell Solar-RECs for cash to MA load serving entities   Solar-REC Non-Compliance Penalty:  DOER 2010 penalty rate in 2010 at $0.60/kWh   Solar-REC Fixed Price Auction:   Each new solar facility retains the option to sell its unsold Solar-RECs each year-end at a DOER auction for a fixed price of $0.285/kWh.  Solar-RECs purchased at auction have compliance value for the 2-3 years following auction Anticipated Solar-REC Value:  Solar-RECs sold in the market are expected to be priced between the penalty rate ($0.60/kWh in 2010) and the DOER auction price ($0.285/kWh) Creating a Greener EnergyFuture for the Commonwealth 11 11

12. MA Solar-RECs (continued) Timing: Program launched Jan. 1, 2010 Solar-REC Eligibility:  Any solar facility sited anywhere in MA, including MLD territories, may sell Solar-RECs Solar-REC Program Duration:   Between 13 and 18 years (program wrap-up tied to speed of MA solar build-out) Program Stability:   Annual program cost of $150-200mm at maturity is borne by all MA rate-payers, but remains a small fraction of the roughly $8 billion MA annual electric bill  Market-Driven Program: Solar-RECs involve no fiscal cost to the MA state government 12 12

13. Solar’s Environmental Benefits Increasingly Valuable • Future Federal Climate Legislation would impose a cost of carbon and raise the price of coal and natural gas-fired electricity • Solar project retains future right to sell carbon offsets instead of Solar-RECs • A 2MW solar facility eliminates over 50 million lbs. of CO2 over system lifetime • Equal to removing 300 cars (at 7,100 lbs C02/year) from road (source: SolarBuzz Feb 2009)

14. Solar’s Secure Cash Flow Supports Project Debt Long-Term Power Purchase Agreement (PPA) with set annual rate escalationprovides the revenue base needed to support targeted debt repayment Solar-REC Revenues from sale to large Investor-Owned Utilities (NStar, National Grid, etc.) whose expenses are reimbursed by ratepayers Federal Investment Tax Credit (ITC) Grant pays 30% of total project cost in cash within 60 days of electric service, thereby reducing project capital costs Strong Collateral: Installed PV system with long-term PPA contract, site control, and all operating permits provides durable collateral for project debt 14
