Telangana Issues Deviation Settlement Regulations for Solar and Wind Generation

The regulations will not apply to rooftop solar PV projects


The Telangana State Electricity Regulatory Commission (TSERC) has issued new regulations for the forecasting, scheduling, and deviation settlement of solar and wind generation sources.

These regulations will apply to all wind or solar generators (excluding rooftop solar PV projects) in Telangana connected to the intra-state transmission system. This would include those connected through pooling stations and supplying power to the DISCOMs or to third parties through open access, or for captive consumption and selling power within or outside the state.

The new regulations are set to apply to all wind and solar energy generators that have a minimum capacity of 5 MW and are connected to the state grid independently or through pooling sub stations.

These regulations will come into effect from the date of publication in the Official Gazette of Telangana. The regulations are meant to facilitate large-scale grid integration of solar and wind generating projects while maintaining grid stability and security.

TSERC - Deviation Charges in-case of Under Over Injection

Telangana has become the eighth state after Uttar Pradesh, PunjabMaharashtraHaryanaAndhra PradeshGujarat, and Tamil Nadu to issue rules for the forecasting, scheduling, and deviation settlement of solar and wind generation.

According to the regulations, wind and solar project developers would be required to appoint a Qualified Coordinating Agency (QCA) to perform meter readings, data collection, and communication. The QCA would also be tasked with coordinating with the distribution companies (DISCOMs), state load dispatch centers, and other agencies, as well as overseeing the settlement of deviation charges.

The wind or solar generator shall provide payment security to SLDC by way of a bank guarantee obtained from a public-sector bank or a revolving letter of credit given by a scheduled commercial bank covering deviation settlement mechanism payments for six months.
