With the support of the United States Agency for International Development, NARUC for a decade worked to facilitate training, information exchange, and technical assistance through the Energy Regulators Regional Association (ERRA), representing regulatory bodies in Europe and Eurasia. NARUC played a pivotal role in helping to develop the capacity of both the individual regulators and ERRA as a whole, initially by organizing technical forums, meetings, and study tours and developing a website for the organization.

As ERRA grew, NARUC supported the drafting of guiding principles for ERRA and the preparation of issue papers that helped member regulators tackle increasingly complex and technical regulatory issues. NARUC also helped ERRA organize highly successful conferences, bringing together a wide array of regulators and industry players, and assisted ERRA in developing more formal, structured training programs to serve the evolving needs of the organization.

From June 2003 to January 2009, ERRA provided training to 805 members and 294 non-members through its comprehensive training program. The ERRA training initiative features a variety of junior to advanced level bilingual courses offered in traditional classroom and/or online formats.

NARUC and ERRA were instrumental in helping member commissions establish their structure and procedures, playing an important role in promoting regulatory independence and transparency. Through the initiative, regional regulators were able to make significant advances in reforming their national energy sectors and explore areas for cooperation and harmonization to promote regional improvements.
