A tariff review by the International Trade Administration Commission of South Africa (Itac) of input materials and components used in wind, solar PV and battery storage facilities could have far-reaching implications for the renewables sector and electricity consumers. In a Gazette notice, Itac indicates that it will review 82 tariff codes for inputs and materials used in the renewables and storage value chains, including everything from solar panels and generators for wind turbines, to lithium-ion batteries, aluminium and steel structures and even screws, bolts and nuts used in renewables installations.
