How we deliver

Project Delivery & Financing

Every project has unique financial, operational, and contractual requirements. Ameresco helps customers evaluate and implement delivery and financing structures that align projects with organizational goals, performance requirements, and budget constraints.
Energy Savings Performance Contracts (ESPC) ↗
ESPCs enable organizations to implement improvements using future energy and operational savings to fund projects; helping to modernize facilities, reduce deferred maintenance, and improve performance without upfront capital.
Engineering, Procurement & Construction (EPC)
EPC delivery provides a single point of accountability for engineering, procurement, and construction execution, helping customers manage risk while improving schedule and cost certainty.
Power Purchase Agreements (PPA) ↗
PPAs allow organizations to purchase energy from renewable generation assets through long-term agreements. Customers can gain access to new energy resources without directly owning the infrastructure.
Design-Build ↗
Design-Build integrates engineering, design, and construction responsibilities within a single delivery structure, helping improve coordination, streamline decision-making, and reduce project complexity.
Energy as a Service (EaaS) ↗
EaaS provides access to upgrades through service-based agreements that shift ownership, operational responsibility, and performance management to a trusted partner; reduce capital requirements while providing predictable outcomes.
Property Assessed Clean Energy (PACE) ↗
PACE financing provides an alternative funding mechanism for eligible infrastructure improvements, allowing costs to be repaid over time through property tax assessments.
