Energy Stabilization Fund Memo 3-19-2021 v3 — File 211467
To: Somerville City Council
From: Oliver Sellers‐Garcia, Director; Bob Ross, Energy Manager
Date: March 19, 2021
Re: Energy Stabilization Fund creation and funding proposal
Background and purpose
This memorandum presents a proposal to create an Energy Stabilization Fund (ESF) for the
implementation of projects that reduce carbon emissions and energy costs for City operations.
To continue reducing our carbon footprint, the City needs to invest in more complex energy efficiency
and electrification measures in its building portfolio. The City has reduced its buildings emissions nearly
20%, mostly through state grant‐funded LED lighting upgrades. Beginning in 2021, because of an
expected reduction in state grant funding and utility incentives for such low‐hanging fruit projects, there
will be a greater need for City investment in the next generation of projects, such as heat pumps,
automated building controls, and ductwork upgrades. The ESF would provide a new, sustainable source
of funding to meet the City’s ambitious commitment carbon neutral City operations by 2035.
Funding and tracking
Where savings from energy projects have historically reduced the City’s overall operating budget, the
ESF will allow the City to invest these savings into additional carbon emissions reduction. The ESF will
use savings or revenue from solar net metering credits (SNMC), demand‐response program incentive
payments, and other efficiency and renewable energy projects to reinvest into greenhouse‐gas
reduction measures in our buildings. At the outset, we propose to fund the ESF through free cash in the
amount equivalent to savings and revenue from 2019‐present (listed below). In subsequent years,
annual savings will be calculated, and requests will be made for free cash appropriations to the fund
based on the prior year’s energy cost savings and revenue, thus rapidly growing the fund every year.

We are requesting an initial free cash appropriation of $294,399. These funds will be used for the few
remaining low‐cost/short‐payback lighting projects, as well projects that eliminate and reduce fossil fuel
combustion in City buildings.
