Meghalaya State Electricity Regulatory Commission (Forecasting, Scheduling and Deviation Settlement for Solar and Wind Generation) Regulations, 2018

  • / /

HIGHLIGHTS

 

Eligible Entities

  • All wind and solar generators in Meghalaya connected to the following:
    • Intra-state transmission system.
    • Pooling sub-stations.
  • The combined installed capacity of generators connected to a pooling sub-station should not be less than 1 MW.
  • The installed capacity of individual generators connected to some other sub-station should not be less than 1 MW.

 

Forecasting & Scheduling Code

  • Qualified Coordinating Agency (QCA) shall provide a day-ahead and week-ahead schedule to the SLDC.
  • Day-ahead schedule – At intervals of 15 minutes for the next day, starting from 00:00 hrs of that day.
  • Week-ahead schedule – Same as for day-ahead schedule, for the next seven days.
  • Revision can be done by giving notice; effective from the 4th time block - the 1st being when notice was given.
  • One revision for each time slot of one-and-a-half-hour subject to a maximum 16 revisions during the day.

 

Role of QCA and Implementation

  • One QCA for each pooling sub-station or generating station registered with SLDC.
  • QCA shall be the single point of contact with respect to:
    • Meter reading, data collection and its communication.
    • Coordination between distribution licensee, SLDC and other agencies.
    • Commercial settlements between generators and their counterparties.
    • All other ancillary or incidental matters.

 

Commercial and Deviation Settlement

  • Generators connected to the intra-state transmission network and selling power within the state, to be paid as per actual generation.
  • Generators connected to the inter-state transmission network and selling power outside the state, to be paid as per scheduled generation.
  • Deviations for intra-state and inter-state transactions at pooling station shall be accounted for separately.
  • SLDC shall provide separate energy and DSM accounts for inter-state and intra-state transactions.  

 

OTHER PROVISIONS

 

Deviation Charges for sale of power within the state

Under or over injection (for plants commissioned before  the date of notification)

Absolute Error in a 15-min time block

Deviation Charges payable to State DSM Pool

≤ 15%

None

>15% but ≤ 25%

At Rs.0.50 per unit.

>25% but ≤ 35%

At Rs.0.50 per unit for the shortfall or excess beyond 15% and up to 25% + Rs.1.00 per unit for balance energy beyond 25% and up to 35%.

>35%

At Rs.0.50 per unit for the shortfall or excess beyond 15% and up to 25% + Rs.1.00 per unit for balance energy beyond 25% and up to 35% + Rs.1.50 per unit for balance energy beyond 35%.

 

Payment Mechanism

  • QCA shall separately settle deviation charges with wind and solar generators for inter-state and intra-state transactions.
  • QCA shall also de-pool the deviations and deviation charges to each generator.
  • QCA shall pay the amount of deviation charges to the SLDC and collect from the generators.
  • Deviation charges shall be paid within 10 days from the date of issue of account and billing of accounts.
  • Delay in payment will attract late payment surcharge of 1.25% per month for the period of delay.

 

Metering

  • Every pooling station or standalone generator with installed capacity of 5 MW and above shall have a special energy meter.
  • QCA shall furnish weekly meter readings to the SLDC.
