On May 18 2000 the Law for the Protection of Electricity Generation using Combined Heat and Power came into force for the first time. In accordance with the Law on Combined Heat and Power, network operators are obliged to recompense energy from existing CHP plants and purchase it under certain conditions. The CHP law also regulates the promotion of new construction and expansion measures for the heat grid, by obliging the network operators to make additional payments for the implementation of projects concerning the heat grid.
The transmission system operators (TSOs) perform financial load equalisation amongst themselves for the compensated CHP premiums; this leads to a nationwide equalisation of payments from the CHP law. The network operators can transfer the charges from the CHP law to the system usage charges.
