01 Industry overview

The esco industry at a glance

The global energy service company (ESCO) market reached approximately $42 billion in 2024, with more than 75% of investment concentrated in the United States and China.

Market size
Global ESCO investments reached approximately $42 billion in 2024, up 10% from 2023. In the United States, ESCOs reported aggregated revenue of $10.7 billion in 2024.[15][20]
Forecast & CAGR
The International Energy Agency reports average annual global ESCO growth of 5% over the five years to 2024. Lawrence Berkeley National Laboratory projects U.S. annual industry revenue of $15.0 billion in 2027, compared with $10.7 billion in 2024, equivalent to an implied annual growth rate of about 12% over the period.[12][20]
Market share & regions
The United States and China together account for more than 75% of global ESCO investment, while China, the United States and the European Union collectively account for more than 90%. China recorded more than $22 billion in ESCO project values in 2024, and U.S. revenue was largest in the Pacific census sub-region at $1.54 billion.[12][15][20]
Segmentation
Buildings represented nearly 60% of ESCO projects captured in the 2024 IEA-UNEP survey, with public buildings accounting for two-thirds of the buildings segment. Industry represented 34% of projects and transport approximately 9%; in the United States, public and institutional customers accounted for 78% of ESCO revenue in 2024.[12][20]
Key players & concentration
The market is geographically concentrated rather than reported through a single global company ranking: more than 75% of global ESCO investment occurred in the United States and China in 2024. The United States accounted for 18% growth in ESCO investment in 2024, while China exceeded $22 billion in project value.[12]
Pricing
ESCO project economics are commonly structured around long-term performance contracts. In 2024, private-sector projects had an average payback period of just over six years and contract duration of about eight years, compared with nearly ten years and about twelve years, respectively, for public-sector projects.[12]
Trends, drivers & challenges
Growth is being driven by energy-efficiency and emissions-reduction policies, public procurement and financing mechanisms; global ESCO investment rose 10% in 2024. Key constraints include high transaction costs, contractual complexity, policy uncertainty and the difficulty of aggregating small residential projects.[15][12]
Consumer behavior & competition
ESCO demand is strongest among public and institutional customers that can use long-term contracts and performance guarantees to reduce upfront investment barriers. Average reported energy savings were approximately 25% globally in 2024, while public-sector projects generally supported longer contracts and broader integrated retrofits than private-sector projects.[12]
Regulation
Regulation is a major market enabler: the U.S. Energy Act of 2020 required federal agencies to implement at least half of identified efficiency measures through performance contracting. In Europe, the European Commission’s 2025 Action Plan for Affordable Energy set an objective to double the ESCO market to approximately $4–6.5 billion per year.[12][15]
Latest news
The latest U.S. ESCO industry report, published by Lawrence Berkeley National Laboratory on September 15, 2026, reported $10.7 billion of 2024 revenue and projected $15.0 billion of annual revenue in 2027. An IEA commentary published on March 13, 2026, confirmed that global ESCO investment reached a record $42 billion in 2024 and highlighted continued concentration in the United States and China.[20][12]
