Helping Businesses Turn Power To Profit

American DG Energy offers customers a simple way of producing energy on-site to improve their bottom line by reducing the cost of electricity, heat, hot water, and cooling. Our solution for on-site energy generation provides customers a way to avoid the required capital outlay which can then be invested or utilized in other aspects of the business, and requires no capital outlay or maintenance efforts. In addition to monetary gains, American DG Energy enables businesses to position themselves as environmentally responsible corporate citizens.


Our "no cost, no responsibility, no risk, just savings" approach makes saving from On-Site Utility solutions straightforward and easy. Customers sign agreements and pay only for the energy they need and use. Our monthly invoices include a guaranteed discount rate below a customer's prevailing local utility rates on the energy we sell. There are no capital costs or operating expenses for the customer. Typically, as soon as we begin producing energy on-site, customers realize enhanced cash flow and increased net income. They also receive direct operational gains because there is no impact on the property's staffing, overhead, or balance sheet.


By outsourcing the ownership, management and financing of energy systems to American DG Energy, customers enjoy the significant economic benefits of distributed electricity, heat generation and cooling systems without requiring the capital investment, specialized in-house technical skills and manpower, operational responsibility, or ownership. We handle all elements of a project from start to finish: site evaluation, financing, engineering, project management, installation, communications, start-up, service, operation, performance optimization, fuel purchasing, utility relations and any other project and system requirements.


While American DG Energy primarily owns the energy systems, we are open to creating joint ventures of co-ownership with our customers that may have the necessary capital resources, but desire American DG Energy’s experience and expertise for maintenance and operations. Or we can simply provide turnkey installation services.


American DG Energy's significant installed base of owned sites and systems continues to expand throughout the United States. Our customers include properties such as: healthcare facilities (assisted living, long-term care and hospitals), multi-tenant housing, hotels, colleges, athletic facilities, food processing, industrial, and institutional properties.

If your properties are located in the UK or Europe, our subsidiary, EuroSite Power has you covered.
