Island Institute
• Work to sustain Maine’s island and rural coastal communities and exchange ideas and experiences to further the sustainability of communities in Maine and elsewhere– Energy: Increase local capacity and share replicable models that help
to develop strategies to lower energy costs
New England Market
New England Market
• Islands vs. islanded
– Roughly two dozen island grids participating in our programming
• Seven of which are islanded*
• All of which are connected by island culture and power system constraints
– Hundreds of other islands inhabited seasonally
Denotes offshore islanded grid*Islanded grids include: Matinicus and Monhegan (ME), Appledoreand Star (NH), Cuttyhunk and Naushon (MA), Block (RI)
NE Islanded Grid Overview
• Small
– 60-75 up to 1,000 people
• Seasonality
• Mixed use
– Year-round fishing communities
– Research centers
– Historic retreat

Wind Resource
NWF
• 4 out of 7 islanded grids have explored wind, only one has installed
Fox Islands Wind
• Project overview– 4.5 MW (3 x 1.5 MW GE)
– Coop-owned, built in 2009
– 10 miles offshore but grid-tied
• Islanded grid “connections”– Offshore deployment
– Community ownership
– Innovative financing model
– 2010 fuel substitution pilot with electric thermal storage
– Public acceptance
Vinalhaven Island, ME
Penobscot Bay, ME – August 2009
Offshore Wind• Block Island, RI
– Deepwater Wind
– 30 MW (5 x 6 MW)
– Lower rates by 40%
• Monhegan, ME
– University of Maine/Maine Aqua Ventus
– 12 MW (2 x 6 MW)
• Martha’s Vineyard
– Vineyard Power & OffshoreMW collaboration
Solar
125 kW PV array with 4,800 Ahr battery bank
Naushon Island, MA
132 kW PV array with 600 kWh battery bank
Star Island, NH
• All 7 islanded grids in New England have installed or have begun to pursue PV over the past three years
Efficiency First!
• Inventory use
• Identify opportunities to aggregate demand for bulk purchase
• Size it right

Challenges
• Tier IV!
• Seasonality of load
• Confusion over options
– How to address heating loads?
• Public acceptance
• Serious lack of funding
– ME: $100K for renewables per year
• Technical resources for operators
Tier IV compliant genset, Block Island Power Company
Next Steps
• Peer-to-peer and other networking
• Comprehensive energy planning
• Documenting best practices for stakeholder engagement
