Technical connection fee Its introduction was prompted by the fact that the existing tariff regulation system prevents distribution grid companies from meeting the growing demand for connection to the energy grid because of material restrictions on tariff increases. The basis of the scheme is as follows: anybody who wants to be connected to the grid shall bear all the costs required for the increase in the Energo-JSC’s grid capacity. The amount of the connection fee is calculated on the basis of the region’s mid-term demand for grid capacity increase. Currently, such a fee is levied in the regions which suffer a serious deficit of grid assets *2009*2010* * – planned Technological connection services (billion RUB net of VAT) 5

Tariff calculation using Return on Regulatory Asset Base (RAB) method It is expected that during 2010–12 there will be a gradual transition from the ‘Costs + ’ method of regulating tariffs for electricity transmission via the distribution grid, to the ‘Return on Regulatory Asset Base’ (RAB) method. The RAB method is aimed at providing full return of funds invested into company assets during the period determined to correspond to asset service-life, and at normalised revenue earning, the level of which is set by the Government, and which shall correspond to the RSK’s risk profile and its sector prominence to investors. Required gross earnings at RAB method = Operational costs + Return on Asset Base + Yield on Asset Base Asset Base WACC (regulatory) Operational costs include all productions costs, excluding depreciation of a company’s tangible and intangible assets. Return on Asset Base shall provide for replacement of the assets used intensively for electricity transmission via the MRSK grid. Yield on Asset Base is calculated on the basis of regulated rate of return (regulatory WACC) established by the regulator, the rate of which will be established for the long-term regulatory period and will be the same for all MRSK. 6
