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

MPRP – Proposed Solution
5
MPRP - Out-of-Date Vision of the Electric Grid
Very large Generation Stations WERE the most efficient forms of generation
6
MPRP - Out-of-Date Vision of the Electric Grid
Manufacturing – that WAS best served by Large Central Generation Stations
7
MPRP - Out-of-Date Vision of the Electric Grid
Transmission WAS easy to site and permit
8
MPRP - Out-of-Date Vision of the Electric Grid
Information WAS difficult to obtain and process
9
GridSolar Offers a Different Vision of the Electric Grid
Load growth is weather sensitive
10
GridSolar Offers a Different Vision of the Electric Grid
Generation placed near the load
11
MPRP - Out-of-Date Vision of the Electric Grid
Transmission is NOT easy to site and permit
12
GridSolar Offers a Different Vision of the Electric Grid
Information is easier to manage

GridSolar Project
Install distributed solar generation to meet actual (not projected) peak loads
When solar will not meet peak loads: Install propane/natural gas fired distributed
generation in dual role of back-up generation plus grid-tied generation
Demand-response using interruptible loads Battery backup as the technology
improves
16
Solar is the only renewable resourcethat is coincident with peak loads

Will GridSolar Work
YES - the ability of the GridSolar Project to ensure grid reliability is acknowledged by CMP.
In addition:less costly better job opportunitiesless risky less impact on the environment

GridSolar – Next Steps
Maine – Stipulation Work with Utility to develop smart grid
plan and platform plus 2 or 3 pilot projects in Maine for implementation
Elsewhere Identify opportunities to work with
consumer advocates in other states to support the GridSolar Project as a Non-Transmission Alternative to peak load growth and ensuring grid reliability
