OTHER PROVISIONS

 

Allotment Priority
  • Priority 1: (Highest Priority) - Distribution licensee (irrespective of whether open access sought is for long-term, medium-term or short-term).
  • Priority 2: Other long-term open access applicants.
  • Priority 3: Other medium-term open access applicants.
  • Priority 4: Other short-term open access applicants, subject to capacity availability.
  • Existing customer shall have priority over new customers.
Open Access Charges

Transmission Charges

  • Payable on the basis of contracted capacity/scheduled load or actual power flow, whichever is higher.
  • Where a dedicated transmission system used for open access has been constructed for exclusive use of a customer, the transmission charges shall be borne entirely by such customer.
  • Transmission charges = ATC/(PLST X365) (in Rs./MW-day).
    (ATC = Annual Transmission Charges as decided by SERC
    PLST= Peak Load Projected to be served by transmission company).

Cross Subsidy Surcharge

  • Payable on per unit basis for actual energy drawn through open access.

Wheeling Charges

  • Payable on the basis of contracted capacity/scheduled load or actual power flow, whichever is higher.
  • Wheeling charges = (ARR – PPC - TC) /(ALSD X365) (in Rs./MW-Day)

(PPC= Power Purchase Charges, TC= Transmission Charges, ALSD= Total Average Load Projected).

Additional Surcharge

  • Payable on per unit basis. The obligation of the licensee in terms of power purchase commitments has been and continues to be stranded, or there is an unavoidable obligation.
  • Determined by the Commission against detailed calculation statement by distribution licensee.
Scheduling, system operations and metering

  • Inter-state OA: Scheduling as per Central Commission.
  • Intra-state (5MW+): Scheduling as per State Grid Code.
  • Intra-state (below 5MW): No scheduling, if the generating station is subject to scheduling.
  • Charges for inter-state OA: RLDC and SLDC charges.
  • Charges for intra-state OA:
    • LTOA, MTOA – SLDC charges
    • STOA – Composite charge of Rs.2,000/day, or as determined by the Commission.

Metering

  • For 5MW+: Special meters to be installed by STU or distribution licensee.
  • Below 5 MW: Special meters to be installed by the concerned distribution licensee.
Energy Losses

Transmission Losses

  • Inter-state :
    • LTOA, MTOA - Buyer shall bear appropriate energy losses.
    • STOA – Buyer and seller shall absorb losses.
  • Intra-state: Determined by Commission in the tariff order and payable in kind.
  • Transmission Losses for FY 2015-16: 4%

Distribution Losses

  • Determined by the Commission for various voltage levels in their tariff orders and apportioned in proportion to the actual energy drawal by the open access customers and shall be payable in kind.
Imbalance and Reactive Energy Charges

Imbalance Energy Charges

  • Load of less than 5 MW: Difference between the applicable sanctioned open access load and the actual drawal shall be accounted through the Time of Day (TOD) meters, on monthly basis, and settled at the rate of the imbalance charge as determined by the Commission. Where imbalance charge has not been determined by the Commission, UI charges as specified by the Central Commission shall be applicable.
  • Unless specified otherwise by the Commission, UI rate for intra-state entity shall be 105% (for over-drawals or under generation) and 95% (for under-drawals or over generation) of UI rate at the periphery of regional entity.
  • In case of under-drawal as a result of non-availability of the distribution system or unscheduled load shedding, the open access consumer shall be compensated by the distribution licensee at the average power purchase cost of the distribution licensee.
  • Load of 5 MW and above ,and the generating stations irrespective of capacity, shall be settled based on the composite accounts for imbalance transactions issued by SLDC on a weekly cycle based on net metering in accordance with the charges specified by the Commission. In case the imbalance charges are not specified by the Commission, the UI charges as specified by the Central Commission shall be applicable.
  • Unless specified otherwise by the Commission, UI rate for intra-state entity shall be 105% (for over-drawals or under generation) and 95% (for under-drawals or over generation) of UI rate at the periphery of regional entity.

Reactive Energy Charges

  • 5 MW or above: The payment in accordance with provisions stipulated in the State Grid Code or IEGC.
  • Less than 5 MW: Charges to be calculated on power factor basis.
