The challenge

Villages beyond a reliable grid connection get power in windows, which is enough for lighting and not enough for an enterprise or a clinic to depend on.

Our solution

A microgrid solution providing 24x7 power to six villages, enterprises and essential services (Phase 1).

Scope of supply

  • Lithium-ion batteries
  • BMS and EMS
  • Power conversion systems (PCS)
  • Photovoltaics
  • Logistics, ground works and manpower on site

Application

Solar Farm, Microgrid, Telecom Tower

What changed

Six villages have round-the-clock power in Phase 1, along with the enterprises and essential services in them.

The distinction is the whole point. These settlements had electricity in windows before, which runs a household but will not support anything that has to be depended on — a clinic's refrigeration, a workshop taking an order, a telecom tower. Storage is what converts solar generation into a supply, and the EMS is what lets one system serve loads that different without any of them destabilising the others.

Questions we are asked about this

A local generation and distribution network that runs independently of the main grid. Photovoltaics generate, lithium batteries store, a power conversion system delivers usable AC, and an energy management system balances supply against demand. The storage is what turns daytime generation into a 24-hour supply.

Yes. This installation supplies six villages in Nagaland continuously, including their enterprises and essential services, in Phase 1 of the project.

Because maintenance visits are difficult and infrequent. LFP needs no watering and has no terminal corrosion to clean, tolerates sitting partly discharged without losing capacity, and reports its own health — none of which is true of a lead-acid bank on a hillside.

The lithium-ion storage, BMS and EMS, power conversion systems and photovoltaics, plus logistics, ground works and on-site manpower — the installation as well as the equipment, which on remote sites is most of the work.
