Merit Order Dispatch Principle

Not applicable to supply of power from renewable energy sources to the distribution licensee or local rural grids within the state.

 

Subsidy or/and Incentives by Government

Any incentive or subsidy offered by the government including accelerated depreciation benefit shall be considered.

Taxes and Duties

  • Tariff inclusive of direct taxes such as income tax.
  • Taxes, duties and cess, other than direct taxes, shall be allowed as pass through.

Transmission and Wheeling Charges and Losses

  • As per UERC (Terms and Conditions of Intra State Open Access) Regulations, 2015 with amendments from time to time for open access to intra-state transmission system.
  • No charges payable for sale of electricity to distribution licensee or local rural grid within the state.
  • For supplying electricity outside the state, charges for dedicated lines and substation, for evacuation of power, shall be payable as determined by the Commission on case to case basis.
  • Transmission and wheeling losses will be adjusted in kind as per UERC (Terms and Conditions of Intra State Open Access) Regulations, 2015 with amendments from time to time.
  • There will be no ‘in kind’ adjustment in losses for supply to the distribution licensee within the state or local rural grid.

 

Evacuation of Power

  • Distribution licensee shall provide connectivity to the RE based generating stations having capacity up to 25 MW at its nearest distribution sub-station, preferably within a range of 10 kilometers from the location of such generating station.
  • Transmission licensee shall provide connectivity to the RE based generating stations having capacity above 25 MW at its nearest transmission sub-station, preferably within a range of 10 kilometers from the location of such generating station.

 

Connectivity and Metering Arrangement for Grid Interactive Rooftop and Small Solar PV Plants

  • Connectivity allowed at following voltage levels:
    • Load up to 4 kW: low voltage, single phase supply.
    • Load above 4 kW and up to 75 kW: low voltage, three phase supply.
    • Load above 75 kW and up to 1000 Kw: at 11 kV.
    • Supply of electricity shall be measured either by two separate meters or by one bi-directional meter.
    • Interconnection shall be as per the Central Electricity Authority (Measures Relating to Safety and Electricity Supply) Regulations 2010, as amended from time to time.

Metering Arrangement

  • RE based generating station shall provide meter at the point of interconnection.

Banking of Power

  • Banking of energy up to 100% would be allowed during peak hours.
  • Withdrawal of power allowed only during off-peak hours.
  • Withdrawal of banked power is allowed during the same financial year in which the power was banked.
  • Banking charges shall be 12.5% of the energy banked.
  • Banked power remaining unutilized at the end of the financial year shall be treated as sale at tariff determined by the Commission in its tariff order or at the generation tariff specified by the Commission in case of a non-fossil fuel based co-generating stations.
  • Non-captive non-fossil fuel based co-generating stations will be eligible for banking only if they have a PPA with the distribution licensee in the state.
