Satrokala, Madagascar

In the village of Satrokala in Madagascar, two renewable energy storage systems, supported by lead batteries, have been installed by Tozzi Green.

A leading player in sustainable rural electrification, Tozzi Green’s installation in Madagascar generates electricity through a combination of wind turbines and solar panels.

The renewable energy generated provides public lighting and more than 20,000 litres of fresh water for the 1,500 residents of Satrokala every day. It also supplies the facility of JTF Madagascar with electricity and irrigation for their offices and warehouses.

“Energy is provided for numerous educational facilities, a sports field and a range of public buildings such as city hall, a bank and a town hall.” Tozzi Green

Technical Specification

The first system, installed in Satrokala in 2013, was rated 15 kW/ 57.6 kWh. Energy was generated through a combination of a 10 kW TN535 wind turbine and a 1.5 kWp PV plant.

The battery energy storage system was based on OPzS 1200 Ah C10 batteries for a total capacity of 2400 Ah at 48 V, allowing demand for energy to be met throughout the day and night.

As energy demand increased in the years since 2013, the installation system was upgraded by Tozzi Green. A new 60 kW wind turbine was added, and the storage system is now rated 600 kWh. The energy storage capacity is now 12480 Ah at 48 V, using RA12-260 gel batteries, provided by Ritar Power.

An ISO 40’ container (pictued) contains the storage batteries and static converters.
