- Teraco, A Digital Realty Company and provider of interconnection platforms and vendor-neutral colocation data centres, has signed a power purchase agreement (PPA) with South African based integrated energy aggregator NOA to supply wind powered renewable energy to Teraco’s data centres.
Teraco, which announced late last year that it had commenced construction on its own 120MW solar PV plant in the Free State, has signed this PPA to complement its renewable energy programme with wind power. The agreement provides Teraco and NOA with the flexibility to grow renewable energy offtake as both companies evolve to meet increasing demand.
Wind is a key renewable energy resource for data centres which operate 24/7/365. In South Africa, wind generates power through the night and into the early morning, making it an excellent complementary source of power to solar, which is generated during daylight hours. The combination enables far greater levels of renewable energy coverage.
Under the terms of the deal, NOA will wheel renewable energy from various wind projects to Teraco’s facilities. The renewable energy wheeled to Teraco’s facilities will complement Teraco’s solar programme, maximising renewable energy across Teraco’s data centres. These projects will ramp up progressively over time with the first power anticipated to be wheeled in 2026.
Wheeling renewable energy across electrical grids enables power to be moved from a renewable energy producer in outlying areas via existing transmission and distribution systems to end-users located in urban areas. It also enables the deployment of renewable energy projects to areas with high energy yield to maximise renewable energy generation potential.
