India project: Successful inauguration of our smart DC mini grid

On 6th June 2017, a smart DC mini grid was successfully inaugurated within the framework of the dena Renewable Energy Solutions Programme. Sarvantara, a village in Uttar Pradesh, India has been equipped with a DC mini grid containing hybrid storage systems powered by photovoltaic panels. The first 30 households are now connected to the grid and provided with sustainable energy. The project is implemented by BOS Balance of Storage Systems AG (BOS AG) and has been installed together with local partner Oorja Development Solutions Ltd (Oorja). The whole project is coordinated by the German Energy Agency (dena) and co-financed by the German Federal Ministry for Economic Affairs and Energy (BMWi)

Opening ceremony in the village
On 6th June 2017, a smart DC mini grid was inaugurated in Sarvantara, Uttar Pradesh. BOS AG, Oorja and Mr. Schmid, a representative of dena, welcomed 20 guests in the village. First, BOS engineers introduced the smart technology of the DC mini grid to their guests. After a tour through the village the mini grid was successfully put into operation. The guests, among them representatives of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and the Indo-German Energy Forms (IGEF) were all very impressed by the technology.

The smart DC mini grid
The DC mini grid has a central energy station equipped with a solar home system, a hybrid storage system and the BOS smart grid signal transmitter. With the smart grid signal transmit-ter, energy consumption can be optimized. The hybrid system contains a combined, fully-fea-tured charge controller for lithium-ion and lead acid batteries that manages the state of charge of both batteries smartly. Thanks to this modern hybrid storage solution, the batteries’ lifetime is guaranteed for at least five years. Through photovoltaic modules, renewable energy is pro-duced and powers lights, fans and USB charging ports. Power consumption is paid by each household individually.

The project
The village Sarvantara is located in a rural area with no access to the grid. The goal of the project is to power 100 households with clean and sustainable energy in the next few months. Over the past two weeks, BOS AG and Oorja have successfully installed the DC mini grid and connected the first 30 households to it. For on-site support and quality control, local technicians have been trained and villagers have received detailed information about the system.
The dena RES Project India is part of the worldwide dena Renewable Energy Solutions Pro-gramme coordinated by Deutsche Energie-Agentur (dena) - the German Energy Agency - and co-financed by the German Federal Ministry for Economic Affairs and Energy (BMWi) within the German Energy Solutions Initiative.
