Sustained high power demand and surge in renewable energy flow from Rajasthan have pushed loading at key transformers and transmission lines carrying electricity to northern India beyond safe operating limits, particularly during daytime solar generation hours, the region’s grid operator has warned.

In a communication dated September 30 to the Central Transmission Utility of India Ltd (CTUIL), the National Load Despatch Centre (NLDC) of Grid-India urged CTUIL to expedite implementation of network augmentation measures to overcome the constraints.

NLDC said the region has been experiencing sustained high demand since April, while a rapid increase in renewable energy capacity in Rajasthan had led to higher power transfers towards Northern Region load centres.

“This is resulting in high loading of Interconnecting Transformers (ICTs) and downstream transmission elements at several major substations such as Moga (PG), Bhiwani (PG) and Jhatikara (PG),” it said.

“These constraints are likely to become more…
