Estimating the cost of capital for wind energy investments in Turkey

Wind power represents a key component of Turkey’s national energy strategy. Based on data collected on 138 installations in the country, this paper provides an estimation of wind power’s cost of capital in Turkey. This analysis finds that the cost of capital for wind power in Turkey compares with the one of South-east European countries. On this basis, continued governmental commitment to current support schemes for wind power must be considered as crucial to further promote wind power deployment in the country, even if the recent devaluation of the Turkish lira raises the feed-in-tariffs cost for the government.

The research was carried out with the kind support of Stiftung Mercator.

Wind power represents a key component of Turkey’s energy strategy. Increased investment will be required to meet Turkey’s wind power target and, as such, there is a need to understand the viability of wind power projects there. The cost of capital is a crucial element in wind power investment decisions owing to the high capital intensity of wind power plants. A reduction in the cost of capital through support policies can lower overall project costs and increase investment.

We estimate the cost of capital for wind power projects in Turkey using data on 138 installations that participated in the Turkish feed-in tariff scheme in 2017. Our estimates indicate an upper bound of 12% for the cost of capital. This suggests the cost of capital for wind power projects in Turkey is not higher than in south-eastern European Union countries. However, because of adverse macroeconomic conditions, the cost of Turkey’s main renewable support scheme increased by 46% between 2016 and 2017 in Turkish lira terms. We argue that continued commitment to the current support schemes by the Turkish authorities is crucial for the development of the Turkish wind power sector.

Is Europe’s gas and electricity price surge a one-off?

Surging natural gas prices in Europe, driven by rising demand and tight supply, are pushing up electricity prices; to prevent volatility, governments need to commit more clearly to a low-carbon future.

A whole-economy carbon price for Europe and how to get there

Putting carbon pricing at the centre of the EU climate policy architecture would provide major benefits. Obtaining these benefits requires a uniform, credible and durable carbon price – the economic first-best solution, however, several preconditions required to attain this solution are not yet met. This paper proposes a sequenced approach to ensure convergence of the policy mix on the first-best in the long run.
