Decarbonizing China’s power system with wind power: the past and the future

Wind power in China has experienced significant growth since the beginning of this century. Total installed capacity has increased almost 300 fold – from 346 MW in 2000 to 91,413 MW in 2013. This rapid development however has created new set of challenges. In particular, wind power has not been fully integrated into the electricity system as a whole, as the growth of wind generation capacity has not been matched by a corresponding growth in transmission capacity…

The impact of a feed-in tariff on wind power development in Germany

“We estimate the impact of a feed-in tariff for renewable power on wind power investment in Germany at the county level from 1996-2010 controlling for windiness and access to the electricity transmission grid. After the Renewable Energy Law (EEG) was passed in 2000, the feed-in tariff became linked to wind power potential, such that more windy locations received a lower incentive per unit of output…”

The power of transformation : Wind, sun and the economics of flexible power systems

Based on a thorough review of the integration challenge, this publication gauges the economic significance of variable rernewable energies integration impacts, highlights the need for a system-wide approach to integrating high shares of VRE and recommends how to achieve a cost-effective transformation of the power system…

Certain legal aspects of the multilateral trade system and the promotion of renewable energy

(…) On the occasion of recent WTO cases that contain findings against Canada in relation to a regional measure aimed at the promotion of renewable energy, it may be pertinent to examine the degree to which the existing WTO normative framework may permit its members policy space to take measures aimed at promoting renewable energy. To that end, we provide a tour d’horizon of the WTO rules that are likely to be engaged by such policies. As part of this, we examine the GATT/WTO system’s evolved responsiveness towards environmental objectives. Finally, we highlight whatever perceived systemic obstacles might exist to the meaningful bridging of the WTO’s environmental objectives with its core trade liberalization objectives…

Effectiveness of policies and strategies to increase the capacity utilisation of intermittent renewable power plants

Intermittent renewable energy sources, such as wind and solar, will become increasingly important in the electricity supply mix if ambitious renewable energy targets are to be met. This paper presents evidence on the effectiveness of different strategies and measures to increase the capacity utilisation of wind and other intermittent renewable energy plants…

The market value of variable renewables

The income that wind and solar power receive on the market is affected by the variability of their output. At times of high availability of the primary energy source, they supply electricity at zero marginal costs, shift the supply curve (merit-order curve) to the right and thereby reduce the equilibrium price of electricity during that hour…

The Impact of Wind Power on European Natural Gas Markets

This IEA’s working paper examines three vital questions associated with this premise: 1) Is natural gas indeed the best partner fuel for wind power? 2) If so, to what extent will an increasing market share of wind power in European electricity generation affect demand for natural gas in the power sector? and 3) Considering the existing European natural gas markets, is natural gas capable of fulfilling this role of partner for renewable sources of electricity?
