Decision-making in the energy sector and notably the power industry has to cope with multiple uncertain factors such as renewable forecasts, technology developments or demand growth. At the same time, multiple methods are available to support decision-making under uncertainty. The focus of the present review is to identify the merits of different optimization modelling approaches…

Towards Electricity Markets’ Integration and Investment in Transmission Capacity: East African Community Power Markets
This research examines the impact of transmission expansion on a future East Africa’s electricity market, to enable the five examined countries (Kenya, Uganda, Tanzania, Rwanda, and Burundi) to adequately couple. As a pioneering move, we introduce nodal pricing and investigate the economic welfare arising from the planned transmission upgrade. This simulation is then compared to…

How Renewable Energy is Reshaping Europe’s Electricity Market Design
We present a systematic review of the challenges to the regulation of electricity markets that are posed by the integration of variable renewable energy sources. System integration is the key to developing the required flexibility, because flexibility options exist at all system levels and within the competitive as well as in the regulated (network) domains….
Policy Reversals in Transitional Markets: The Effect of Changing Marginal Cost to Physical Order Dispatch in the Mexican Power Sector
This study explores the 2021 Mexican electric reform that proposes changing the power dispatch from a marginal-cost-based to a command-and-control physical system. The new law forces the state power company to dispatch before private generators. We use the GENeSYS-MOD techno-economic energy model to determine the reform’s effect on the power sector’s generation mix, energy emissions,…
Electricity Markets in Transition and Crisis: Balancing Efficiency, Equity, and Security
Two electricity market crises following the lifting of post-Covid restrictions in 2021 and the natural gas supply interruptions in 2022, challenged the functioning of the EU electricity market and its design. This paper argues that the market design was already ripe for an overhaul as the efficient market paradigm has gradually become an instrument of…
Fossil Fuel Subsidies, the Green Paradox and the Fiscal Paradox
Fossil fuel subsidies amounted to about 0.4% of global GDP in 2015, and there is an active call worldwide for eliminating them. The main argument in favor of removing subsidies is that it will lead to a reduction in global carbon emissions and a decrease in fiscal deficits. This paper shows that there are also…
(Anti) Competitive Effects of RES Infeed in a Transmission-Constrained Network
Many countries are adding substantial capacities of wind- and solar-based power generation to their portfolios. While ownership of conventional capacities is typically concentrated, renewable energy (RES) is often provided by new, independent producers. Hence, one might expect competitive pressure to increase as RES production is ramped up. However, the best locations for RES are often…
Winners and Losers of EU Emissions Trading: Insights from the EUTL Transfer Dataset
This paper analyses distributional effects between participants of the EU Emissions Trading System (EU ETS) during its first trading period. To this end, a selection model is formulated and applied to a dataset based on account information and transfer data from the EU Transaction Log (EUTL). Four different ways of adding carbon prices to the…
