RedT sells 14 units to Botswana-based customer

Energy storage company RedT energy announced the sale of 14 units into sub-Saharan Africa on Monday, which its board described as a “key growth market” for the company.

The AIM-traded firm said 14 of its 40kWh modules had been purchased by the unnamed Botswana-based customer, who would use the machines to provide energy security at “critical communications infrastructure sites” across the country.

All 14 sites were to be in remote locations with no grid connection, and would use 11kWp of solar panels per site as the sole form of generation.

RedT said its units would be used to store a proportion of the solar energy generated during daylight hours for use during the evening, in a process known as 'timeshifting' which effectively creates 'firm' 24h solar power - making it cheaper per kWh of energy than running a diesel generator off-grid.

The company claimed its technology was chosen for the project owing to its long service life, low maintenance requirements and the product's ability to operate at “challenging sites”, where conventional lead-acid and lithium batteries had been used but experienced “critical failure”.

RedT, which has an office in South Africa, said it had already deployed “a number of units” in sub-Saharan Africa, and viewed the region as a “key future growth market” for its products.

“This represents a sizable commercial order for redT after deploying our initial units in South Africa,” said RedT CEO Scott McGregor.

“Low cost secure energy, achieved by combining solar with a RedT energy storage machine is key to bringing reliable power to Africa where 700 million people don't have access to grid electricity.

“We look forward to continuing to deliver secure energy to the African market.”
