The power plant has an installed power of 1,000 megawatt (MW) (4 x 250 MW reversible turbine-pump groups)

The achievement of the Tarnita-Lapustesti hydro power plant with pumping accumulation implies the provision of investment funds of over EUR1.1 billion, without VAT, reads a draft GD posted on the website of the ministry, on April 13, 2009.

As per the Substantiation Note, the achievement of the investment for the Tarnita-Lapustesti hydro power plant will lead to the improvement of the operating regime of the large groups of Cernavoda Nuclear-Electric Plant, of the fossil fuel thermo-power plants functioning by condensation and of the cogeneration thermo power plants, by operating the Tarnita-Lapustesti CHEAP as a top plant.

Given the importance of the investment objective, it is necessary to adopt a Government Decision which would specify the modality of selecting the investors for the achievement of the Tarnita-Lapustesti CHEAP investment objective, of initiating proceedings for the set up of a company, as provided by the strategy and approve the draft articles of incorporation of this trading company, as well as of constituting an inter-ministerial commission called the Coordination Commission and a Technical Secretariat to coordinate the process of selecting consultants and investors, reads the Substantiation Note. To achieve this investment, a company will be established, to attract strategic investors as shareholders.

The Tarnita-Lapustesti pumping unit will produce electricity and will use the energy surplus from the low load hours. The plant will function as a pump at night, when energy is cheap, and as a producer, generating electricity, in the daytime. The hydro power plant will be a consumer of energy and will provide continuous overnight operation of the central types where stop and start occur in a long time, as for example the two Cernavoda reactors.
