Tata Power Delhi Distribution (Tata Power-DDL) is fully prepared to ensure adequate power availability during this winter season to a populace of 7 million in its area of operations in North Delhi.
The company is expecting the peak demand to touch 1500 MW this season and has made long-term power tie ups for meeting the same effectively. A total of 1700 MW of power is available from long-term sources with the company which would help in meeting the peak demand effectively. However, the overall winter peak demand for Delhi is expected to touch a record high of 4,800 MW.
“Tata Power-DDL is fully committed to ensure warm and safe winters to its consumers and this is only possible through an uninterrupted power supply. We have made surplus arrangement of up to 200 MW power over and above the expected peak demand and it will also cater to contingencies. Besides this, we are using a mix of smart technologies like AI & Machine Learning for better load forecasting to provide reliable power supply,” said Ganesh Srinivasan, CEO, Tata Power-DDL.
Our power-supply arrangements during the winter-months include long-term agreements from power-plants like Maithon Power, NTPC Stations, and Delhi based gas fueled generating stations. Additionally, the company will also be receiving around 20 MW from Solar Energy Corporation of India (SECI) and 80 MW from Sunedison GreenKo.
Apart from these, Tata Power-DDL is also using advanced techniques and avenues like ‘Banking’, ‘Reserve Shutdown’, ‘Power Exchange’ and ensuring sufficient ‘Spinning Reserves’ to dispose of surplus power . In case of any unforeseeable contingency, the company will buy short-term power from the exchange which is available at economical rates during winter months. Adding to these efforts are the advanced load-forecasting statistical and modelling techniques which are helping us forecast the power demand.
Use of Technology
Tata Power-DDL is extensively using technology in ensuring reliable power supply, like advanced statistical forecasting models, combined with state-of-the-art weather forecasting solutions, including Artificial Intelligence (AI) and Machine Learning. Domain expertise provided by Power System Operation Corporation Limited- India Meteorological Department (POSCO-IMD) also helps.
Tata Power-DDL will also bank surplus power with hilly states, which need additional power during the winter months. This banked power will be available during the summer months of 2020.
Demand (load) forecasting is critical for reliable power supply. It is done on various parameters like (i) Day-ahead in 96 time-slots, (ii) Intra-day basis and (iii) Medium term (from a fortnight to one year). Among other aspects, weather parameters like Temperature, Rainfall, Cloud Coverage, Wind Speed, Wind Direction and Humidity play an important role in accurate demand forecast. This accurate day ahead, intra-day and medium term demand forecasting is vital for optimal and cost effective planning in ensuring reliable power supply to consumers at an optimal cost.
Winter Peak Demand in Tata Power-DDL’s Area:
- 2019-20 (Expected) : 1500 MW
- 2018-19 : 1433 MW
· 2017-18 : 1390 MW
