Danfoss Industries and Sara Incorporated commissioned a 270 Kw\/Hr Battery Energy Storage System, S-Grid, at Danfoss\u2019s India Plant to provide system flexibility while charging it from the 1.2 MW Solar plant installed on the premises.<\/p>

\u00a0<\/p>

Danfoss Industries Pvt Ltd. (Subsidiary of the 7 Billion Euros in sales Danfoss Group with its HQ in Denmark) and Sara Incorporated, inaugurated India\u2019s first privately owned and managed grid-scale battery-based energy storage system, S-Grid, in Oragadam, Chennai. The 270 kilowatt-hours (KWh) system, designed and commissioned by Sara Incorporated, will pave the path for the wider adoption of grid-scale energy storage technology across India.<\/p>

\u00a0<\/p>

Battery-based energy storage enables electricity to be stored and then delivered within milliseconds, reducing the instability of the electric grid and enabling more energy to be captured and delivered on-demand. India has the ambitious vision of installing 250 GW of renewable energy generation by 2025.<\/p>

\u00a0<\/p>

Battery-based energy storage provides the flexibility and agility to better integrate intermittent solar and wind energy resources into India\u2019s electric grid and ensure high-quality power for consumers.<\/p>

\u00a0<\/p>

S-Grid, a 270 KW\/Hr project, is located at Oragadam, Chennai, and will be charged by the 1.2 MW Solar Plant at Danfoss\u2019s facility. This system is part of the journey at Danfoss to become carbon-free by 2030. Danfoss also proposes to add a charging station to this system to enable a fully green vehicle with no fossil fuel requirement for charging.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

As per the proposed policy by the Ministry of Power, ESS developers shall be granted Inter-State Transmission System connectivity under General Network Access (GNA) allowing them to sell\/ purchase power from any part of the country. The quantum of ESS included with Round-The-Clock (RTC) Renewable Energy shall be counted as Renewable Purchase Obligation (RPO) for storage. Renewable Energy Certificates (RECs) may be issued to ESS. Discoms\/ Obligated entities can set up their own storage or procure storage capacity or lease storage space from public or private ESS developers. Any sale of electricity from storage or sale\/ lease of storage space may be through open competitive bidding or Power exchange or through tariff fixed u\/s 62. The policy proposes that transmission cost for RE shall be waived both at the time of charging the storage as well as at the time of selling the stored RE.<\/p>
