The District of Columbia Municipal Aggregation Program (DC MAP) is an initiative that unifies the purchasing power of DC electricity customers who opt into the program, according to RetailEnergyX. DC MAP is now seeking a vendor who can help increase awareness among the residents, businesses and institutions that can participate, with the goal being to increase participation by 20 percent over the next 12 months. Although participation in the program has been limited to date, DC MAP saved customers $5.4 million for a 24-month contract and $30 million for a 36-month contract, according to the program website. The program has operated since 2004 using a reverse auction procurement methodology.
