Karnataka Electricity Regulatory Commission has notified the “Forecasting, Scheduling, Deviation

settlement and related matters for Wind and Solar Generation Sources) Regulation 2015

(KERC/CT/1/15 dated 31 May 2016.

Karnataka is the first state to release the Forecasting & Scheduling regulation in the country.

Executive Summary of “Forecasting, Scheduling, Deviation settlement and related matters for Wind

and Solar Generation Sources) Regulation 2015

Applicability of Regulations (Section 3.2)

All wind generators having combined installed capacity of 10 MW and above at the pooling

station (Section 3.2 (a)).

All wind generators having combined installed capacity of 5 MW and above at the pooling station

(Section 3.2 (b)).

Existing wind and solar generators needs to comply with the regulation within six months from

the date of publication of the regulations in the official gazette (Section 4.1).

All the new wind and solar generators which shall be commissioned after six months from the

effective date of the regulation shall comply these norms before commissioning of the project

and connecting with the state grid (Section 4.2).

Virtual Pool (Section 4.8)

The wind & solar generators either by themselves or through the Aggregator/QCA may opt for

aggregation of Forecasting and Scheduling of different pooling stations to enable larger

geographical integration and furnish scheduling of Integrated pools at 15 minutes time block to

SLDC and in such case any pooling and depooling of the DSM charges shall be done only at

their level.

Computation of Error (Section 2(j) & 7.1)

Computation of error quantity

The following formula shall be adopted for this purpose:

% Error (deviation) = ((Actual Generation – Scheduled Generation)X 100) / ((Available

Capacity (AvC))

F&S at Inter- State level (Section 7.4)

The energy charges shall be paid to the generators

i. As per the actual energy supplied irrespective of the Schedule quantum of energy for the

generators for intra-State Transactions

ii. As per the Schedule energy for the inter-State transmission which are governed by the

CERC regulations.

Frequency of Revision (Sec 4.9)

Deviations will be calculated on the basis of Available Capacity (AvC). 16 revisions allowed during the

intraday with each revision effective from 4th time block.

Tolerance limits and deviation bands (Sec 7.3)

The permissible deviation for all the wind and solar generators shall be (+/-) 15% beyond which penalty

is applicable.
