Cap and trade systems are considered to be one of the most cost-efficient options to achieve emission reduction targets. This paper extends the literature on the evaluation of emissions trading systems (ETS) by providing insights into the methodology of the ex-post evaluation of cost-efficiency. Based on data from the second trading period of the EU…
What Models Tell us about Long-term Contracts in Times of the Energy Transition
Uncertainty is a major hindrance to attracting investment for the energy transition. Yet European market design is mainly discussed with a focus on short-term efficiency. Based on computational results from market models for gas and power we derive lessons on the importance of contracts and the implications of incomplete markets. Specifically, we show that short-term…
Running Randomized Field Experiments for Energy Efficiency Programs: A Practitioner’s Guide
Researchers and professional evaluators are increasingly turning to randomized field experiments to evaluate energy efficiency programs and policies. This article provides a brief overview of several experimental methods and discusses their application to energy efficiency programs. We highlight experimental designs, such as randomized encouragement and recruit-and-deny, that are particularly well suited for situations where participation…
Socio-technical Inertia: Understanding the Barriers to Distributed Generation in Pakistan
In a bid to promote renewable energy, Pakistan issued net-metering regulations in 2015 that allowed for on-site solar and wind generation. However, five years on, overall growth in Distributed Generation (DG) remains insignificant. Here we investigate the reasons why, focusing on solar prosumage and exploring the key barriers and challenges in the existing socio-technical regime….
Analytics on Pricing Signals in Peer-to-Peer Solar Microgrids in Bangladesh
Solar microgrids enabling peer-to-peer energy exchange among off-grid households are poised to contribute to electrifying rural areas in the Global South. This novel approach provides underserved communities with affordable, green and reliable energy access, capable of powering higher-tier consumer as well as productive-use appliances. To ensure these microgrids can be run sustainably, this paper seeks…
Model-Based Evaluation of Decentralised Electricity Markets at Different Phases of the German Energy Transition
This paper investigates decentralised markets in the German electricity system, defined as markets in specific regions in which regional electricity demand is met primarily by regional generation and the remaining demand is met on a system-wide level in a second step. The research question is: What impact do the size of decentralised markets and the…
Fossil Natural Gas Exit – A New Narrative for the European Energy Transformation Towards Decarbonization
This paper discusses the potential role of fossil natural gas in the process of the energy transformation in Europe on its way to decarbonization. Mainstream conventional wisdom has it that natural gas, perhaps in combination with other gases, should maintain an important role in the energy mix, first, as a “bridge fuel”, and then through…
Facilitating Transmission Expansion to Support Efficient Decarbonization of the Electricity Sector
Many governments, electric utilities, and large electricity consumers have committed to deep decarbonization of the electricity sector by 2050 or earlier. Over at least the next 30 years, achieving decarbonization targets will require replacing most fossil-fueled generators with zero carbon wind and solar generation along with energy storage to manage intermittency and for balancing more…
Biomethane for Electricity in Mexico: A Prospective Economic Analysis
The Cost of Finance and the Cost of Carbon: A Case Study of Britain’s only PWR
This paper argues that the cost of decarbonising depends critically on the Weighted Average Cost of Capital (WACC), illustrated with a case study of Sizewell B (SZB, the nuclear station commissioned in 1995). It calculates the cost per tonne of CO2 abated with prices set as for transmission assets by the regulator under the Regulatory…
