The Kerala State Electricity Regulatory Commission (KSERC) has approved Kerala State Electricity Board Limited’s (KSEBL) petition to enter into an agreement with Manikaran Power Limited for banking surplus power from August 1, 2024, to September 30, 2024, with a return to Kerala between March 16, 2025, and May 31, 2025.

RERC issues suo motu order on tariff determination regulations for 2025
The Rajasthan Electricity Regulatory Commission (RERC) has issued a suo motu order on the RERC (Terms and Conditions for Determination of Tariff) Regulations, 2025 after considering inputs from various stakeholders.
The commission noted concerns that once the multi-year tariff (MYT) structure is finalized, no major changes should be introduced during the control period. Some stakeholders requested that the regulations be published in Hindi for better accessibility. There were also discussions on definitions, with suggestions for clarifications on additional capital expenditure, auxiliary energy consumption, and availability calculations. Concerns were raised about the need for independent verification of data instead of relying solely on the state load despatch centre (SLDC).
Regulations on capital structure and cost were also debated. Some stakeholders proposed incorporating non-wires alternatives such as energy efficiency and demand response to reduce system costs. Others suggested that insurance expenses be accounted for separately from operation and maintenance costs.
On tariff determination, stakeholders emphasized the need to align state regulations with national clean energy goals. A revenue decoupling mechanism was proposed to eliminate the disincentive for discoms to promote energy efficiency and rooftop solar. Additionally, there were calls for introducing new key performance indicators beyond transmission and distribution losses to better evaluate utility performance.
