Haryana Electricty Regulatory Commission announced the DSM regulations for wind and solar, 2019 along with the statement of reasons recently post the draft discussion paper in 2018. The summary of the regulations is as below:

Title: Haryana Electricity Regulatory Commission (Forecasting, Scheduling and Deviation Settlement and related matters for Solar and Wind Generation) Regulations, 2019.


  • From the date of publication in the official gazette.
  • Levy and collection of DSM Charges shall commence after six months from the date of publication in the official gazette.

Regulation to be applicable on:

Regulations will apply to all Wind and Solar Energy Generators in Haryana connected to a particular Pooling Sub-Station, or that of an individual Generator connected to some other Sub-Station not be less than 1 MW to the Intra-State Transmission /Distribution System, including those connected through Pooling Sub-Stations, and using the power generated for self-consumption or sale within or outside the State  combined installed capacity of the Solar or Wind Generators.

Deviation Accounting: The deviation accounting will be carried out based on the Available


Point of forecasting: Pooling sub-stations and /or Intra-state transmission/distribution system.

Aggregation: No provision of Aggregation, unlike AP and Karnataka where it is allowed.

Role of QCA:

  • Meter reading and data collection and its communication, and coordination with the Distribution Licensees, the SLDC and other agencies
  • De-pooling of amount among other generators
  • Settlement of the Deviation Charges specified in these Regulations with the SLDC on behalf of the Generators.


  • 16 revisions to be submitted for both wind and solar generators starting from 0.00 hours of the day.
  • All the revisions are effective from the 4th time-block

Key points:

  • The Deviation Charges shall be paid within ten days from the issuance of the invoice along with a statement of account by the SLDC, failing which an interest of 0.4% per day for each day shall be levied for the period of delay.
  • In case of any curtailment communicated by the SLDC due to line maintenance or other reasons in certain time blocks of a day, the QCA shall be responsible for curtailing the generation at the site and revising the Schedule accordingly, failing which the SLDC shall revise the Schedule as required.

Inter- & Intra-state deviation settlement transactions:

  • Deviations in respect of Inter-State and Intra-State transactions shall be accounted for separately at each Pooling Sub-Station.
  • Inter-State transactions at a Pooling Sub-Station shall be permitted only if the concerned Generator is connected through a separate feeder.
  • The QCA will submit a separate schedule on behalf of the generator for its energy generation to the SLDC and the concerned RLDC.
  • The SLDC will prepare the deviation settlement account for such generator on the basis of measurement of the deviation in the energy injected and its impact at the state periphery.

Deviation Charges for Intra-state sale of power

Deviation Charges for Inter-state sale of power

Deviation charges for under- or over-injection for intra-state transmission and selling/consuming power outside Haryana

Deviation Charges in case of under-injection

Deviation Charges in case of over-injection

*The fixed rate is the PPA rate determined by the commission, in case of multiple PPAs, the fixed rate shall be the weighted average of the PPA rates.

The tentative date for the DSM charges to be levied is supposed to be six months i.e. 1st December 2019, after the regulations get notified in the Gazette.
