ABB (Zurich, Switzerland) on September 3rd, 2015 announced that it will install an integrated solar-diesel micro-grid at its Longmeadow premises in Johannesburg, South Africa.
The 96,000 square meter facility houses the company’s country headquarters as well as medium voltage switchgear manufacturing and protection panel assembly facilities, with around 1,000 employees.
750 kW rooftop PV plant, 380 kWh energy storage system
The innovative solution includes a rooftop solar photovoltaic (PV) field and a “PowerStore” grid stabilizer, that will help to maximize the use of solar power and ensure uninterrupted power supply to keep the lights on and the factories running even in the event of a power outage on the main grid supply.
A 750 kW rooftop PV plant and a 1 MVA/380 kWh battery-based PowerStore will be added to the existing back-up diesel generators. This will enhance the use of renewable energy and provide continuity of supply when power supply is disrupted and during transitions from grid to island operation.
Power shortages, availability of renewable energy sources like wind and solar, fossil fuel price volatility and environmental concerns are leading to the search for sustainable solutions and there are thousands of facilities across South Africa and the continent that could leverage microgrid technologies to address these challenges.
