TNERC is scheduled to hear TANGEDCO’s petition on additional R&C measures including the withdrawal of banking recommendation by TANGEDCO. IWTMA, the apex body representing all major wind energy players has appealed recently to the Tamil Nadu Chief Minister against the removal of banking facility for wind power. A number of key stakeholders are watching this development closely and waiting to see the final regulatory order on this petition. The petition is slated to be heard on Tuesday, 10’th July 2012.
TANGEDCO in its petition to TNERC has submitted that Wind Energy Generators had a provision for wheeling and banking facility which has been in force since 1986. But the quantum of banked energy is also increasing exponentially every year (i.e.) as of 31.10.2008 it was 315 MU; as of 31.3.2009 it was 351 MU; as of 31.3.2010 it was 380 MU and now it has grown disproportionately upto 845 MU even during the first 7 months period upto 31.10.2011.
TANGEDCO states that at present the captive users of Wind Energy Generators are drawing maximum power from Feb’12 for their banked energy during wind season. This has created additional burden to TANGEDCO on the shortage of power the petition further states.
The banking of wind energy has complicated the grid management in absence of withdrawal schedules from the captive consumers. The majority of HT industrial consumers are facing 40% power cut and two days of power holidays due to unprecedented power shortage and those consumers with banking facility are upsetting equitable distribution of available power, TANGEDCO has said.
TANGEDCO has submitted that, in the case of wind energy, the power that is generated during the lean period is banked and the banking consumers utilise the same during peak summer without any schedule or premium. The above facility/provision is not covered under any regulation but was made to encourage development of non conventional energy fifteen to twenty years back, no such facilities are extended in any other states in India. The consumption and overdrawal of wind energy consumers cannot be monitored on day to day basis and is a great threat to grid stability. Complimentary benefits extended for promotional purpose decades ago cannot be continued on under severe crisis situation, TANGEDCO adds.
TANGEDCO further notes that by all accounts, there is a strong case not to give a preferential treatment of the banked wind energy captive users. Until ABT meters are provided and real time monitoring brought in, consumption can be noticed only at the end of the month and penal measures become a one time affair for multiple violations committed. The deemed demand concept for banked energy is being exploited by the captive consumers. The direction issued by TANEDGCO for providing ABT meters is also challenged by the OA consumers before High Court, Madras and the matter is sub-judice.
Finally, TANGEDCO submits in its petition that in absence of injection schedule by wind operators/drawl schedule by the banking consumers it is proposed that the facility of banking shall be withdrawn hence forth and that furnishing of Drawl schedule by captive wind consumers shall be made mandatory on day ahead basis.
