This month, the first 30 households have been connected to a smart mini grid in India and provided with sustainable energy is a pilot project by German company BOS Balance of Storage Systems.
Sarvantara, a village in Uttar Pradesh, India, has been equipped with a DC mini grid containing hybrid storage systems powered by photovoltaic panels.
The project is part of a partnership between German energy agency Dena and local company Oorja Development. The project was co-financed by the German Federal Ministry for Economic Affairs & Energy (BMWi).
The opening ceremony (pictured) in the village saw the smart DC mini grid inaugurated. BOS engineers introduced the smart technology of the DC mini grid. After a tour through the village, the mini grid was put into operation. The guests included representatives of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the Indo-German Energy Forms (IGEF).
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 transmitter, energy consumption can be optimised. The hybrid system contains a combined, fully-featured charge controller for lithium-ion and lead acid batteries that manages the state of charge of both batteries smartly.
Thanks to this hybrid storage system, the batteries’ lifetime is guaranteed for at least five years. Through photovoltaic modules, renewable energy is produced and powers lights, fans and USB charging ports. Power consumption is paid by each household individually.
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 and Oorja have successfully installed the DC mini grid and connected the first 30 households. 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 Programme and co-financed by the BMWi within the German Energy Initiative.
