ABB will install an integrated solar-diesel microgrid 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. The solution includes a rooftop solar PV field and a PowerStore grid stabilizer, that will help to maximize the use of clean solar energy.
ABB designed, manufactured, installed and commissioned a 1,200-kV circuit breaker the highest AC voltage level in the world. Once the 1200-kV ultrahigh-voltage switchgear is fully operational, it will have a switching capacity of 10,400 MW - a switch capable of turning ON' or OFF' the electricity generated by 10 large power plants or the combined average annual electrical load of Switzerland and Denmark, within milliseconds.
