 Energy development and investment company focused on large
municipal, commercial and utility-scale solar assets, resiliency, storage
and microgrids. Founded in 2008, Rivermoor was an “early entrant” to
the New England utility and commercial solar market.
 Rivermoor Energy works with leading commercial, governmental and
utility clients with a focus on resiliency solutions, energy storage and
solar development.
 Rivermoor Energy’s clients and partners include (partial list):

Northampton – Critical Assets and Duration
• 10 days chosen as planning
length for an emergency
outage
• 21 day outage would require
significant additional effort
integrating local business
community
• City Department Heads
developed consensus on
critical buildings list
• 42 critical assets evaluated
• Collaborative planning,
shared resources and
leadership are the foundation
for community resiliency

 Risks:
- Single onsite backup generator –
has failed in the past
- Redundancy & disaster recovery “gap”
 Fuel Diversity Recommendations:
- Solar PV, Battery storage and energy
efficiency
- Genset testing & maintenance
- Mobile genset solution “pool”: Pin &
Sleeve set up would be installed
- Benefits: Cost savings, on-site plus
“mobile pool” redundancy, emergency fuel
savings, and fuel diversity

1. Integrate Solar Assets,
Energy Storage and CHP
2. Campus Microgrid
 Leverage hospital’s CHP,
existing and new solar & new
energy storage assets
 Campus microgrid will provide
resiliency improvement for long
outages plus cost savings on
utility energy & demand charges
 CHP “advantage” for two +
facilities rather than one

 Rivermoor Energy developed this solar
asset for the benefit of property owner
National Grid in a development-
construction partnership with Fischbach &
Moore electrical contractors.
 Largest solar asset in Boston.
 1.2 megawatts on a seven acre
contaminated “brownfield” in front of
landmark multi-colored LNG tanks on
Boston’s Route 93.
 Provides clean, local power directly to the
utility grid. Owned by National Grid and
connected to the utility grid by
Eversource.
 $7 + million asset, largest solar asset in
City of Boston.

 Rivermoor Energy developed
this solar asset, working
successfully with Boston Water,
local utility NSTAR (Eversource)
and our design and construction
team of Fischbach & Moore to
develop the largest solar roof in
downtown Boston.
 First solar asset to successfully
utilize Massachusetts SREC
incentives.
 Development, engineering and
construction completed in 2010.
 $1.25 million asset
