Working Paper

Providing efficient network access to green power generators: A long-term property rights perspective

This paper analyses the dynamic efficiency of several types of access regulation of a bottleneck transmission line in electricity markets.

By: , and Date: November 2, 2016 Topic: Digital economy and innovation

Coordinating the timing and location of new production facilities is one of the challenges of liberalized power sectors. It is complicated by the presence of transmission bottlenecks, oligopolistic competition, and the unknown prospects of low-carbon technologies.

The authors build a model encompassing a late and early investment stage, a clean (green) and dirty (brown) technologies, and a single transmission bottleneck and compare dynamic efficiency of several market designs.

Allocating network access on a short-term competitive basis distorts investment decisions as brown firms will pre-empt green competitors by investing early. Compensating early investors for future network congestion, as for instance in the E.U., only exacerbates this problem.

Dynamic efficiency is restored with long-term transmission rights that can be traded on a secondary market (iusvendendi). As early investment lowers the resale value of the transmission rights, brown firms will invest optimally.

The authors show that dynamic efficiency does not require the existence of physical rights for accessing the transmission line (ius utendi), but financial rights on receiving the scarcity revenues generated by the transmission line (ius fructendi) suffice.

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.
