英文摘要	As part of the sustainable energy transition in Germany, substantial investments in power grid infrastructure are planned. They are intended to provide flexibility to an electricity system increasingly relying on variable renewable energy sources, and on European interconnection. While much research has been done on the benefits of renewables, the economic impact of the necessary grid investments so far remains widely unclear. This paper presents a macroeconomic assessment of the planned investments in power grid infrastructure in Germany. By performing a static input-output analysis, the investigation reveals how multiplier effects of the grid investments impact macroeconomic outcomes – in terms of output, value added, employment and fiscal income. Net multiplier effects on outputs are found to be positive, ranging between €47.3 bn and €55.8 bn, while other effects turn out to be negative. A net decrease in value added of between €10.1 bn and €12.7 bn, in fiscal income between €962 million and €1354 million, and reductions in employment of between 130,170 and 158,940 jobs are found to be attributable to the grid investments. Hence, from a national perspective, the planned investments are found to have mixed macroeconomic effects and are not necessarily 100% 'no-regret'. Flexibility investments for the energy transition provided by power grids should therefore be realized with caution, and at least cost, if negative effects on national value added, tax revenues and employment are to be minimized. For policy guidance, more research is needed on the relative merits of the flexibility options available for accomodating high shares of renewables, and on the overall economic net benefits of sustainable energy transitions. © 2021 Elsevier Ltd
