The ESS must be physically situated at the solar project sites.
The projects must be commissioned within 24 months from the effective date of the power purchase agreement (PPA), with an additional six-month window for delays. The PPA tenure is 25 years.
Project delays and non-compliance with other requirements will result in PBG encashment and potential capacity reduction for delays exceeding six months.

Bidders can choose their preferred storage technology and project locations across India, provided they ensure the availability of ISTS connectivity.
