During 2015, the tariff regulation laws were amended as follow:
- In terms of capacity acquisition on wholesale market for supply to the households and equivalent categories of consumers, and acquisition of capacity by the organization managing the unified national (Russian) power grid;
- In terms of procedure for attribution of electric grid facility owners to local grid operators.
The introduction of these amendments had an impact on the calculation of electricity transmission tariffs for these consumer groups and the reduction in the number of LGOs in the regions where PJSC IDGC of the North-West operates, resulting in a change in tariff solutions as from July 01, 2015. The approved tariffs provided for the aggregate growth of tariff revenues by 12.2% up to RUB 39 billion.
