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 resiliencymileskm

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
