- Abstract:
- Decarbonizing and growing the power sector are critical steps to reducing greenhouse gas emissions in a cost-efficient and timely manner. As more renewable energy enters the market, the higher penetration of solar and wind sources means periods of temporary overgeneration are likely to increase. There are signs that renewable electricity oversupply is now actively being sought in order to create opportunities to decarbonize other sectors or build export markets for products derived from that additional energy. This commentary discusses the role of electricity in deep decarbonization efforts, and how zero-carbon oversupplies might be deployed. Policy makers must assess what public benefits to prioritize under this recent phenomenon. This commentary examines four countries—Germany, New Zealand, Saudi Arabia, and the United States—where excess generation is providing novel opportunities. The case of New Zealand is particularly illustrative of the choices countries and policy makers are facing. There, extra zero-carbon supply has suddenly appeared due to the closure of an aluminum smelter. The reduced load means this new abundance could be used to: expand the transmission infrastructure to feed electric loads elsewhere in the nation, decarbonize non-power sector applications (e.g., transportation or industry), produce and sell new products with near-zero carbon footprints (e.g., hydrogen, ammonia, chemicals, fuels), or operate machines that remove CO2 from the air and oceans.
