FLUCTUATION IN HYDROPOWER GENERATION

Posted On: 27 MAR 2025 5:04PM by PIB Delhi

All India Peak Demand for FY 2024-25 (upto February, 2025) was 2,49,856 MW which occurred on 30.05.2024. This peak demand was successfully met with only a marginal gap of 2 MW.

There is adequate availability of power in the country. Present installed generation capacity of the country is 470 GW. Government of India has addressed the critical issue of power deficiency by adding 238 GW of generation capacity since April, 2014 transforming the country from power deficit to power sufficient. Further, addition of 2,01,088 circuit kilometer (ckm) of Transmission lines, 7,78,017 MVA of Transformation capacity and 82,790 MW of Inter-Regional capacity has been done since 2014 with capability of transferring 1,18,740 MW from one corner of the country to another.

As per mid-term review of 20th Electric Power Survey, the All India Peak Demand of the country is expected to be 277 GW in 2025-26. The country is confident to meet this projected demand with optimal usage of existing and under construction capacities.

Further, Government of India has taken following measures to ensure uninterrupted and reliable power supply in the country:

  1. All the GENCOs including IPPs and Central generating stations have been advised to generate and maintain full availability on daily basis excluding the period of planned maintenance or forced outage.
  2. Hydro based generation is being scheduled in a manner so as to conserve water for meeting demand during peak period.
  3. Planned maintenance of generating units is being minimized during period of high demand.
  4. New power generation capacity is being monitored closely for timely addition.
  5. Steady supply of coal to all the thermal power plants is being ensured to prevent fuel shortages.
  6. Directions under Section 11 of Electricity Act have been issued to imported coal based plants to operate and generate power to their full capacity.
  7. Gas-based power plants of NTPC as well as other generators are being scheduled during high power demand period.
  8. Government has facilitated power trading through regulatory framework whereby states with surplus generation can sell power to states which are in deficit through three (3) power exchanges viz. Indian Energy Exchange (IEX), Power Exchange India Ltd (PXIL) and Hindustan Power Exchange Ltd.
  9. Electricity market has been reformed by adding the Real Time Market (RTM), Green Day Ahead Market (GDAM), Green Term Ahead Market (GTAM), High Price Day Ahead Market (HPDAM) in Power exchange. Also, there is DEEP portal for e-bidding and e-Reverse for procurement of short-Term power by DISCOMs.

The hydro generation during the year 2024-25 (April, 2024 to February, 2025) was 1,39,780 Million Units (MUs) as compared to 1,27,038 MUs during corresponding period of 2023-24, showing a growth of 10 % in Hydro generation. Any shortfall/variation in generation from RE Sources including hydro is handled with corresponding change in thermal generation so as to adequately meet the power demand.

The Government has taken various measures to facilitate the integration of Renewable Energy (RE) resources into the National Grid to ensure reliability and stability as under:

  1. Development of intra-state transmission network is being planned to keep pace with RE capacity addition. Strong inter connection of ISTS RE schemes with the intra-state network to ensure better reliability in terms of anchoring voltage stability, angular stability, losses reduction etc. is being done.
  2. Central Financial Assistance (CFA) is being provided to the States for setting up Transmission infrastructure for RE integration within their State under the Green Energy Corridor Scheme.
  3. Encouraging setting up of RE projects with storage facilities for optimal utilisation of transmission facilities.
  4. Flexibilization of thermal generation is mandated to address the variability of RE generation.
  5.  CEA (Technical Standards for Connectivity to the Grid) Regulations lay down the minimum technical requirements for the RE generating plants to ensure the safe, secure and reliable operation of the grid. The compliances to the said regulations by RE plants are verified jointly by Central Transmission Utility (CTUIL) and Grid-India/RLDCs before granting connectivity/interconnection to the national grid. Robust compliances verification is done before interconnection of any new plant to the grid.
  6. Indian Electricity Grid Code mandates that RE plants participate in the primary and secondary frequency control in case of contingencies. Hybrid RE power plants, Energy Storage Systems such as BESS (Battery Energy Storage System) and PSP (Pump Storage Project) are being promoted for mitigating variability in RE generation and provide adequate frequency support to the grid.
  7. Establishment of dedicated 13 No. of Renewable Energy Management Centres (REMC) in RE rich States and Regions for dedicated, monitoring, forecasting and scheduling of Solar and Wind plants.
