HOW MUCH TRANSMISSION CAPACITY WILL EUROPE NEED IN 2050?

摘要

A coordinated model of the European electricity system is presented, and used to investigate the economic impacts of interconnection capacity between the UK and Norway. As DESTinEE is an open-source model, we hope that it may be used in many future studies which focus on other parts of the European energy system.As could be expected, transmission reduces extreme prices caused by reliance on intermittent renewables. This increases the risk of “missing money” for generators, suggesting that a move to capacity markets could be advisable. Early entrants may be dissuaded from investing, knowing that small increases in transmission capacity can change equilibrium prices in the connected markets, reducing the potential advantage of competitive merchant interconnectors over regulated schemes. This flattening of the price-duration curve leaves fewer arbitrage opportunities for electricity storage technologies and demand-side resonpse; however, it should be noted that storage can also provide reserve and/or relax transmission and/or distribution constraints.
