MPRP - Areas of Need

MPRP – Proposed Solution

MPRP - Out-of-Date Vision of the Electric Grid Very large Generation Stations WERE the most efficient forms of generation

MPRP - Out-of-Date Vision of the Electric Grid Manufacturing – that WAS best served by Large Central Generation Stations

MPRP - Out-of-Date Vision of the Electric Grid Transmission WAS easy to site and permit

MPRP - Out-of-Date Vision of the Electric Grid Information WAS difficult to obtain and process

GridSolar Offers a Different Vision of the Electric Grid Load growth is weather sensitive

GridSolar Offers a Different Vision of the Electric Grid Generation placed near the load

MPRP - Out-of-Date Vision of the Electric Grid Transmission is NOT easy to site and permit

GridSolar Offers a Different Vision of the Electric Grid Information is easier to manage

Maine’s Energy Choice CMP Vision in which peak load is met by large generating facilities located far from load requiring expensive transmission systems GridSolar Vision in which peak load is met through a smart electric grid using small-scale distributed solar generation located close to load

CMP Vision – Phase 1

CMP Vision – Phase 2

CMP Vision – Transmission 765 kV Transmission Lines in Upstate NY

Misconception Not sunny in Maine Maine is relatively cold but also quite sunny. Maine lies well south of most of Western Europe where many solar installations have been developed. Maine has plenty of rain to keep solar panels clean.

Misconception Solar is Not Reliable

Misconception There is not enough land

Misconception PV is not cost competitive NREL Analysis – 2015 States where PV is or is close to price competitive with grid power

Costs of Solar PV are Falling Solar Cost Curve is expected to decline over the next 20 years due to technological improvements, manufacturing scale and new production methods

Misconception Solar is Too Expensive Avoid Very Expensive Transmission Investments Capture Generous Federal Investment Tax Credits and Depreciation Value of Renewable Energy Certificates Sell capacity into New England electricity market. By doing the above - GridSolar can offer for 20 years of fixed energy pricing at 3 cents/kWh

GridSolar is less expensive than MPRP Even after socializing the costs of the MPRP, the GridSolar Project is less costly to Maine Ratepayers

Environmental Benefits At full build-out – Emission reductions resulting from the installation of distributed solar generation will be about 500,000 tons of greenhouse gas a year – the equivalent of taking 100,000 cars off Maine roads.

Economic Development Lower electricity prices for 20 years or longer Opportunity to establish Maine as a leader in the development of solar power and the establishment of “smart grids” Solar Industry – manufacturing, fabrication opportunities in Maine

Misconception Mainers Prefer Transmission
