What Acadia Center does
Mission

As stated on its FY2025 Form 990.
Programs
Energy Efficiency and Building Decarbonization:Acadia Center advocates for policies and programs to upgrade buildings to make them more efficient and healthier. The project advances energy efficiency programs that provide incentives and support to consumers to weatherize and improve the efficiency of their homes and businesses by substituting old energy-hogging equipment for new, more efficient ones. This effort is supported by shifting billions of utility dollars from purchasing expensive power plant contracts into low-cost energy efficiency programs, including through state energy efficiency planning bodies across the region and building energy codes. More efficient housing improves indoor air quality and public health. Using cleaner, efficient systems reduces energy bills. By improving the efficient use of electricity and fossil gas, reductions result in needing costly infrastructure. The project focuses on transitioning buildings to clean, efficient, all-electric heating and cooling systems, and it pursues this work through coalitions, state policies, a building-science approach, and innovative methods that make energy efficiency programs easier for consumers to participate…
$333,814 spentof which $125,000 as grants14% of program spendingClean Energy and Infrastructure:Acadia Center advocates for accelerating the deployment of clean energy on the power grid, from large-scale resources like offshore wind to local, distributed renewables like community and rooftop solar. This work extends to the complex area of reforms to remove barriers to clean power in the regional electricity grid, where our goals include articulating the consumer, health, environmental justice, and climate case against persistent reliance on fossil fuel for electricity in the region. In addition to overarching power grid reform work, the organization is pursuing a suite of grid- and infrastructure-focused projects intended to improve the responsiveness of power grids to consumer, climate, and equity goals detailed below: the Northeast Grid Planning Project (NGPF) is promoting a dialogue among stakeholders and power grid operators in a large area of the northeastern U.S. (New York and New England) with Eastern Canada (Ontario, Quebec and eastern provinces); the Communities and Clean Grid project is a novel effort to plug municipalities into the important work of the regional grid operator and help raise their voices and participation in…
$1,018,358 spent43% of program spendingUtility Innovation and Accountability: Acadia Center advances thought-leading reforms in state and regional utility regulation so all parties engaged in the energy system utilities, regulators, and consumers work together to achieve shared goals. The program builds awareness about how outdated financial incentives influence utility decision-making and can misalign with clean energy deployment, climate goals, and ratepayer benefits. The program has significant reforms of public utility commissions and state regulatory oversight so that they consider climate impacts and equity imperatives alongside reliability, affordability, and safety. Program goals seek to catalyze modernization of the grid and the utility system of the future, with a focus on performance-based regulation, utility performance incentive mechanisms, rate-design for electrification and DERS, integrated distribution system planning (gas/electric), non-wires alternatives, and inclusive stakeholder engagement.
$367,339 spent16% of program spendingClimate Policy and Solutions:Every program and project at Acadia Center touches on climate policy and solutions. Climate Policy represents a dedicated set of activities specifically focused on addressing opportunities for states and the region to achieve overarching climate targets, which require deep, economy-wide decarbonization and phaseout of the use of fossil fuels. Program area activities include engaging with states on comprehensive climate planning studies, modeling, and energy system strategies. This work advances long-term, "big picture thinking," which is needed to ensure that comprehensive and cohesive strategies for decarbonizing entire economies are considered. Climate Policy includes work in Acadia Center's CLEAN-E Analysis team. It embraces three project areas that are essential to the achievement of near- and long-term climate targets at a state and regional level: 1) CLEAN-E/Analysis; 2) Fossil Fuel Phase-Out, and 3) State and Regional Climate Policies, which includes work on programs that set binding caps on emissions (e.g., RGGI, cap-and-invest). In addition, Acadia Center has released "Rapid Response" materials addressing claims made about the costs of clean…

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $5.2M to $6.9M (+33%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 12% · 2023 9%. Grants only. Government contracts and fees sit inside program revenue.
84% of Acadia Center’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 8 funders to 23 funders, grant income rose $483k → $1.7M.
16 of 59 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 33% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $2.2M from 7 payers (the payer shares this organization's board, largest The Energy Foundation). These are real filings, and they are not money Acadia Center raised.
From the IRS filings of Acadia Center’s funders (the co-funder graph). Top 30 of 59 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
Acadia Center has a broad base — no single funder exceeds 24% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
48% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Acadia Center.
Largest funder’s share by year: 2017 62% · 2018 44% · 2019 30% · 2020 27% · 2021 28% · 2022 54% · 2023 29% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
45% of Acadia Center's funders are still giving 3 years after their first grant; 61% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
Acadia Center draws 100% of its grant income from funders outside Maine, across 18 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $3.7M arriving through sponsors registered in 12 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
Acadia Center's funding base is broadening — from 8 funders to 23 as grant income climbed.
