Taiwan is moving to tighten energy management requirements for major electricity consumers, a move that could significantly increase operating costs for TSMC, the world's largest chipmaker, which has become the country's biggest electricity consumer. What's the story? Taiwan’s Ministry of Economic Affairs is leading an amendment to the Energy Management Act, which would require commercial and industrial establishments with high electricity consumption to build their own energy generation and storage facilities, while exempting schools and hospitals from these requirements. This amendment complements the existing renewable energy development regulations, which require large consumers to cover 10% of their electricity consumption through renewable energy sources. However, the new legislation goes further, requiring these facilities to rely on an independent infrastructure for electricity production and storage.
