摘要

Since the late 1990s, countries all over the world have put in place different types of support schemesfor renewable energy. Their goal is to promote these technologies, generally not competitive yet intraditional wholesale markets. By means of such support schemes, market players are incentivized toinvest on renewable plants according to the expectations of the policy makers. The installation ofrenewable generators and the availability of renewable energy sources (RES) is not, however, the onlyprecondition to integrate such production in a power system. Some technical and security constraintsmay limit the full integration of the available RES production, and part of the available RES energymay need to be “curtailed” or “spilled”. This limitation may open the debate about the extent up towhich the installation of RES energy is efficient from a social point of view and should be thereforeincentivized by support schemes.Spain represents a good case for the examination of RES integration issues, with over 100,000 MW oftotal installed capacity by the end of 2011, including about 20,000 MW of wind power, and more than4,000 MW of Solar power. RES curtailments have had to be applied by the Spanish TransmissionSystem Operator (Red Eléctrica de España) on several occasions of high wind production during offpeakdemands in order to guarantee system security.This paper presents an estimation of future RES curtailments in the Spanish power system accordingto the National RES installation objectives, for the years 2015 and 2020. Results show that under allthe scenarios considered, significant RES curtailments are expected to occur. Then, the paperdiscusses technical and regulatory measures that could be put in place in the Spanish power systemwith the aim of maximizing the integration of renewable resources, considering all aspects of theenergy policy: security of supply, environmental sustainability, and economic sustainability.
