(a) whether the Government proposes to make forecasting of power output mandatory for wind
power producers;
(b) if so, the details thereof;
(c) whether the Government also proposes to impose fines on wind power producers that do not
provide daily forecasts of power output; and
(d) if so, the details thereof ?
MINISTER FOR NEW AND RENEWABLE ENERGY (DR. FAROOQ ABDULLAH)
(a)&(b): The Central Electricity Regulatory Commission (CERC) Indian Electricity Grid Code (IEGC)
Regulation, 2010 (known as Grid Code) notified by CERC has mandated all wind generators, connected
to the pooling stations, commissioned on or after 3.5.2010 and with collective capacity of 10 MW
and above at connection point of 33 kV level and above, either to the transmission or distribution
system of the State or to the inter-State transmission System, to make forecasting and scheduling
of wind generated w.e.f. 15.7.2013.
The Grid Code provides that the wind generators shall be responsible for forecasting their
generation upto an accuracy of 70%. If the actual generation is beyond +/- 30% of the schedule,
wind generator would have to bear the Unscheduled Interchange (UI) charges.
For actual generation within +/- 70% of the schedule, no UI would be payable/receivable by
Generator, The host State, shall bear the UI charges for variation,
within +/- 30%. However, the UI charges borne by the host State due to the wind generation,
shall be shared among all the States of the country in the ratio of their peak demands in the
previous month based on the data published by CEA, in the form of a regulatory charge known as
the Renewable Regulatory Charge operated through the Renewable Regulatory Fund (RRF).
(c)&(d): There is no specific penalty, but there are commercial disincentives for not
providing daily forecasts of output power. For instance, if the wind power producer does not
provide daily forecasts of power output (schedule), it would be considered as zero schedule
given to the State Load Despatch Centre. In such cases, wind generators would have to bear UI
charges if the actual generation is beyond +/- 30% of the zero schedule.
