Wind, water and wires: Evaluating joint wind and interconnector capacity expansions in hydro-rich regions
研究了富水地区如何通过协调风电和互联线路投资来最大化联合效益，并用塔斯马尼亚的模型量化了不同情景下的经济吸引力。
Countries or regions with a high share of storage hydro and good renewables resources may be able to interconnect to less well-endowed neighbours. To maximise joint benefits, coordinating interconnector and renewables investment is desirable. Suitable long-term contracts ensure that beneficiaries pay and jointly cover the highly dispersed costs and benefits. The article develops a simple model calibrated for Tasmania that demonstrates how this can be quantified and various counterfactuals tested. The key to the simplification is that the value of water is both stable over time and the key driver of outcomes. The economic attraction of proposed wind and interconnector investment depends sensitively on the value placed on CO2 reductions.
