The National Dispatch Center is responsible to coordinate daily system operation of all power and heat sector entities which includes the real time coordination of the power plants operation, transmission and distribution switching operations, operation of the heat transmission network in coordination with the CHP operations. The currently available hardware and software systems at NDC were not originally designed for the control of the power system network. All communications and data acquisition are mostly communicated by telephone and fax.

The NDC is also responsible for providing the information necessary to settle spot market transactions within the context of the wholesale electric power market which is currently structured on a “single buyer market” model. These responsibilities will be discussed in more details in the sections below.
