The UK model of incentive regulation of power grids was at one time the most advanced, and elements of it were adopted throughout the EU. This model worked well, particularly in the context of limited investment and innovation, a single and strong regulatory authority, and limited coordination between foreign grid operators. This enlightening book shows that since 2010 the whole context has changed and regulation has had to catch-up and evolve. The EU is entering a wave of investment, and an era of new services and innovation which has created growing tensions between national regulatory authorities in terms of coordinating technical standards and distribution systems. This is being played out against an increasingly disruptive backdrop of digitzation, new market platforms and novel business models.
Raising public awareness and trust in transmission infrastructure development is one of the key current challenges facing Transmission System Operators (TSOs) and other project developers. The result can be costly delays. Fine-tuning the regulatory toolbox that National Regulatory Authorities (NRAs) apply to incentivise TSOs can be part of the solution. The toolbox consists of cost-plus or rate of return regulation, price or revenue cap regulation, and output regulation. Each of these tools has strengths and limitations in terms of biases. In this brief, we identify the biases that are specific to stakeholder engagement activities that TSOs undertake to increase the public awareness and trust. Under the cost-plus approach, NRAs are biased towards the least controversial activity. Thus, the TSOs will try to anticipate the costs that will be more easily approved by the regulator. However, these least controversial activities may not be the most effective. Under the price/revenue cap, TSOs can be biased towards prioritising activities that result in the highest direct improvement of cost efficiency. They can also be biased in selecting the least controversial activities rather than the most cost-effective ones, simply because it can adversely affect their reputation and their engagement with the regulator. Under output regulation, independent experts can help the regulator to assess and challenge the stakeholder engagement activities undertaken by a TSO. This approach, however, requires a higher level of sophistication and complexity so that it can only be managed properly by a regulatory agency with sufficient resources and skills.

In many countries, distribution grid tariffs are being reformed to adapt to the new realities of an electricity system with distributed energy resources. In Europe, legislative proposals have been made to harmonize these reforms across country borders. Many stakeholders have argued that distribution tariffs are a local affair, while the EU institutions argued that there can be spillovers to other countries, which could justify a more harmonized approach. In this paper, we quantify these spillovers with a simplified numerical example to give an order of magnitude. We look at different scenarios, and find that the spillovers can be both negative and positive. We also illustrate that the relative size of the countries is an important driver for the significance of the effects. To be able to quantify these effects, we developed a long-run market equilibrium model that captures the wholesale market effects of distribution grid tariffs. The problem is formulated as a non-cooperative game involving consumers, generating companies and distribution system operators in a stylized electricity market.
Although e-commerce has become a common basis for business transactions in most markets, other elements of e-business are not as widely used yet. This paper extends and operationalizes a previously developed e-business process model by Basu and Muylle (2007). Specifically, it presents evaluation measures for each process and an instrument based on those measures, and describes an effective approach to assess firms’ e-business capabilities. The assessment approach is illustrated using data from a diverse collection of firms in the Flanders region of Belgium. This is followed by an illustration of how such assessments can assist firms in identifying e-business initiatives in line with strategic and market priorities, using a subset of the firms as examples.
Modeling electricity storage to address challenges and opportunities of its applications for smart grids requires inter-temporal equalities to keep track of energy content over time. Prevalently, these constraints present crucial modeling elements as to what extent energy storage applications can enhance future electric power systems' sustainability, reliability, and efficiency. This paper presents a novel and improved mixed-integer linear problem (MILP) formulation for energy storage of plug-in (hybrid) electric vehicles (PEVs) for reserves in power system models. It is based on insights from the field of System Dynamics, in which complex interactions between different elements are studied by means of feedback loops as well as stocks, flows and co-flows. Generalized to a multi-bus system, this formulation includes improvements in the energy balance and surpasses shortcomings in the way existing literature deals with reserve constraints. Tested on the IEEE 14-bus system with realistic PEV mobility patterns, the deterministic results show changes in the scheduling of the units, often referred to as unit commitment (UC).
