India’s authorities plan to introduce, from July 1, 2027 a regulation requiring builders of photo voltaic and wind power initiatives to have battery storage put in on the websites in a bid to higher handle the renewable power output and cut back curtailments.
For photo voltaic and wind initiatives commissioned after July 1, 2027, the Central Electrical energy Authority (CEA) of India proposes that builders to be mandated to have co-located power storage equal to not less than 10% of the renewable challenge’s put in capability, with a minimal length of two hours.
The proposed regulation would change into extra stringent for initiatives commissioned between July 2029 and 2031, with battery storage of not less than 10% of put in capability and a minimal length of 4 hours, in accordance with the draft proposals.
Regardless of a serious photo voltaic and wind installations growth lately, India has been struggling to totally make the most of the capacities as a result of output has usually been curtailed because of the lack of battery storage.
Consequently, solar energy builders in India have started to add battery storage to photovoltaic initiatives to draw patrons and cut back the massive share of curtailments for energy provide that the grids are unable to soak up, Santosh Sarangi, Secretary of India’s Ministry of New and Renewable Power, stated final month.
With out battery backup, photo voltaic initiatives see curtailments in the course of the hottest months and peak daytime hours.
India’s electrical energy grid is increasing at a slower tempo than the growth in renewable power installations, resulting in an elevated share of clean energy curtailments and threatening to sluggish the photo voltaic and wind growth on the planet’s most populous nation.
Grid and transmission constraints accounted for practically two-thirds of all renewable power curtailment at 300 gigawatt-hours (GWh) within the first quarter of the yr, clear power suppose tank Ember stated in a report in Could.
In a separate evaluation in June, Ember stated that India wants round 10 GWh of battery storage immediately to cease renewable power curtailment when the coal fleet can’t ramp down beneath its technical minimal.
