Facilitating Sustainable Community Development
Through the Deployment of Advanced Distributed Energy Resources


CADER stands for Communities for Advanced Distributed Energy Resources. Initially, the organization was a California Alliance focused on energy conversion technologies.  Then its membership expanded internationally, and it changed its acronym to convey its focus on the very latest, most efficient technologies and how these can be integrated into communities.


Starting in 2001 CADER organized and sponsored the most informative and influential conferences on the subject of distributed energy resources in the State of California, and many believe in the United States. Annually, these conferences featured the top thought leaders in the field  from government, industry, academic, and the non-governmental organizations in the United States and abroad. The thematic focus of the conferences were as broad and varied as the participants and attendees, running the full range of DER technologies applicable to industrial, commercial, institutional and academic settings.  In 2010, CADER narrowed and deepened the focus of the conference on integrated DER applications to support robust community energy systems. The focus was in response to new Federal priorities and economic stimulus funding of initiatives intended to increase the nation's energy independence, energy security and environmental quality and to rebuild aging community infrastructure. The capacity of community officials and private development practitioners to optimize these initiatives and funding will turn on their capacity to make informed decisions about the integration of DER technologies in their own development projects.

History and Board of Advisors

CADER was founded inside the California Energy Commission in 1998. On August 11, 1999, CADER, Inc. was registered with the State of California and the IRS as a non-profit (501(c)(6)) trade organization. Former California Energy Commission Commissioner David Rohy became CADER’s Chair in 2007 and worked with a board of directors to develop and advance CADER’s  focus on community energy systems.  In 2015 the CADER board adopted a transition plan calling for creation of an advisory board.  Also in 2015,utility and solar industry veteran Gerry Braun became CADER’s chair.  In 2016 CADER’s board of directors voted to approve a partnership between CADER and The Integrated Resources Network under the name IRESN.  All CADER board members agreed continue serving and to join IRESN’s Board of Advisors.

DER Information

For many years CADER served as an information clearinghouse on efficient technologies and infrastructure systems that improve the quality, reliability and security of community energy supplies while reducing energy costs and environmental impacts associated with power generation. The original structure and content of CADER’s website was intended to build foundational knowledge that development practitioners could use to assess the potential value of DER applications for current and future projects and then to further explore promising applications through direct contact with relevant technology consultants and vendors.  Here links to the main categories of CADER’s website content:
FAQs - The content of this linked file provides answers to the most frequently asked questions (FAQs) concerning DER technologies for community applications. For those unfamiliar with distributed energy resources or with limited time, this is the best place to get an overview of their value in the community setting.
Technologies Files linked in this paragraph contain information on local renewable generation, local natural gas generation, and combined heat and power technologies,

Resources- This linked file contains links to all presentations at CADER’s 2010 international conference as well as to reports on municipal level energy efficiency planning and the important role that energy-smart land use planning and urban design play in optimizing the economic and operational efficiency and use of local energy resources.

Consultants & Vendors

CADER developed a national database of municipal energy sustainability consultants, technology vendors and installation firms represent leading professionals in the industry. A more up to date and searchable database is available on the Municipal Sustainability and Energy Forum website.  IRESN has supported MSEF’s work as a member and webinar presenter since 2014. MSEF’s database includes company and practitioner contact information organized by state and industry sector.
