By 2050, the European Union aims to cut the European CO2 emissions by 80-95% compared to 1990. To reach this target, the European power grid plays a key role to ensure both a low-carbon and affordable electricity supply. In this context, the e-Highway2050 project identifies the European grid architectures, which would be needed under five contrasted low-carbon energy scenarios. An innovative approach based on Monte-Carlo simulations of the European power system, modeled with approximately one hundred zones, ensures both robustness of the results and the possibility to consider all of Europe at once. A detailed cost-benefit analysis of the different grid architectures shows their high profitability. Their implementation between 2030 and 2050 in terms of transmission requirements and technological solutions is discussed. © 2016 IEEE.

The progressive re-engineering of the European power transmission system will involve a spectrum of innovative technologies. Their level of application by Transmission System Operators (TSOs) will vary from one control area to the other, also based on past experiences and today's operation constraints. The present paper introduces a Technology Integration Roadmap, developed within the European research project REALISEGRID, with the aim to analyze the evolution of advanced transmission technologies over the next three decades towards their integration into the European power system. This roadmap is based upon a systemic approach which takes into due account two knowledge elements: the transmission system perspective and the technological perspective. It is organized into high level technology components based on a common long-term vision of the European electricity network by 2030, the critical system challenges driving that vision and the overall benefits expected from the implementation of this spectrum of technologies. The present paper proposes an Action Agenda for the next three decades, with potential integration trajectories including milestones as seen by TSOs and manufacturers respectively. © 2011 IEEE.

The OPTIMATE prototype performs simulations involving multiple market areas and heterogeneous market rules. The platform models the sequence of actions conducted by Market Players, Transmission System Operators and Power Exchanges from day-ahead to real time. The recent developments of the platform include intraday and real-time processes with various balancing mechanisms. It enables thus to compare implicit and explicit balancing strategies. Most of the time, implicit balancing is more efficient than explicit balancing. Some results of recent market design studies performed with the day-ahead module of OPTIMATE in the framework of the Market4RES project are also put forward. © 2016 IEEE.

The paper introduces first the key drivers of the present evolution of the electric system and shows how the network is the key element to integrate an increasing amount of renewable generation. Then, the smart grids philosophy is introduced: this concept, initially specifically associated to distribution systems, is more and more related to the transmission grid too. Depending on different factors, transmission grid investments may also address distribution grid issues and be more generally beneficial for the system. The transmission system itself has also to evolve to handle new challenges in a situation in which authorization for new lines is becoming increasingly difficult. Hence, important opportunities are offered by the new transmission technologies. The paper presents a review of the most important of them, showing their degree of maturity. The results shown here are based on some activities of the European FP7 project REALISEGRID © 2011 IFAC.

Recent research suggests that policymakers would benefit from analyzing further how homeowners think about renovation. Charlie Wilson, a lecturer at the Tyndall Center for Climate Change Research at the University of East Anglia, led a study published in 2015 in the journal Energy Research and Social Science concerning homeowner decision making with regards to renovations. The study included interviews with homeowners, an extensive review of published articles and reports, and a survey of 1,028 homeowners in the U.K. Traditionally, companies or authorities seeking to encourage homeowners to undertake energy efficiency measures identify three groups of barriers that must be overcome: Financial barriers such as capital availability; information barriers such as uncertainties about contractor reliability; and decision making barriers including the reluctance to make complex and irreversible decisions. However, Wilson says that this approach may not accurately describe how homeowners consider renovation decisions. "I'm not a major fan of thinking about this in terms of barriers," he says. "People aren't sitting around the kitchen table saying 'I want to make my home more energy efficient but these barriers are getting in the way, if only there was a good policy that would remove these barriers.' People are more saying, 'It would be good if we could make that room more air-tight, or that room a bit less damp and draughty so we can make it a child's playroom.' People are asking how they can best adapt their home to meet their needs." Wilson explains that many policies designed to encourage energy efficient home renovations miss an opportunity by treating them as discrete, one-off renovations. He believes the key to increasing energy efficiency measures is for them to accompany more general renovation projects. "The challenge is how can we 'piggyback' energy efficiency measures into that vast amount of home renovation activity which is going on every day in Europe," he says. "Imagine that you are going ahead with a 10,000 pound kitchen refurbishment and the supplier or builder says 'By the way, there is this new scheme that means while we do your whole kitchen we can do a bunch of insulation measures and put in new windows so your home will be more energy efficient—this will go on to your energy bill and you pay it back over time.' "The research that we did showed that people were far more likely to go for that kind of policy support." Karine Laffont, an engineer and consultant at French innovation management firm Technofi, agrees that attempting to bundle efficiency measures in with general renovations would prove successful. "Energy does not cost enough —at least in France—to put energy issues at the top of the agenda for households," she says. "And I don't think raising environmental concerns is enough to make people renovate." "If people are already planning on making some home improvements to increase their comfort in terms of living space, acoustics, aesthetics or humidity for example, and if there is a business model that is in place that can help them make those renovations in an energy efficient way that will not cost much, then I think they will do so." Laffont also points to energy contracting as a further way to increase energy retrofits on a larger scale, such as targeting whole apartment blocks. She is collaborating with BRESAER, a European project that is developing a retrofit design that aims to deliver near zero energy performance to existing buildings via the use of building envelope technologies including dynamic windows, insulation panels and photovoltaic modules integrated into a structural mesh. "We had a look at what kind of business model would mitigate [financial barriers] and what we identified is the energy contracting model," Laffont says. Through agreements between housing associations, builders and manufactures, energy contracting models—such as EnergieSprong in the Netherlands—can deliver energy retrofits to groups of houses or apartment blocks with no upfront payment for occupants. "The contractor takes over the commercial, technical and operational risks of the project," Laffont says, "And the contractor will also guarantee the performance of the outcome." While zero energy new builds are now commonplace, existing buildings will make up an estimated 70 percent of Europe's building stock in 2050, indicating that encouraging homeowners to undertake energy efficiency measures is a crucial part of a low-carbon future.

The worldwide energy consumption of buildings is expected to grow by 45% from 2002 to 2025, according to the SMART 2020 study carried out by the international NGO the Climate Group. To reduce energy demand in old buildings across Europe, a consortium of researchers has designed an industrialised façade system for use in retrofitting works. The system brings an imaginative technological solution that can be applied to different types of building and façade orientations. "This system provides the tools for producing energy as well as insulating the building better: two major issues of the coming years in Europe," explained Julen Larraz Astudillo, architect at the Sustainable Construction Division of the TECNALIA research centre, located in San Sebastian, Spain. The insulation technology is ready now for full-scale implementation in a real building in Merida, a city in the south of Spain, following a series of extensive tests, which checked its fire, water, wind, impact, acoustic and permeability resistance. The fire test was the most demanding. "We had many concerns about it, due to the new composite materials the façade is made of (glass fibres and an organic binder) and the complexity of the units. Many of them had different technologies and elements that could fail the test," says Julen Astudillo. The façade proved to be fire resistant, in compliance with European standards. The façade's technology, developed under the research project MeeFS, was also submitted to heavy object impact tests. During the wind trial, the façade was subject to pressures until up to 305 kg/m2. "We checked the different components of the façade; they didn't break and the distortion of these elements lasted just one minute," he adds. A particular unit of the façade, the advanced passive solar collector and ventilation unit, was required to pass special tests, like acoustic and permeability tests. This is because it connects the interior and the exterior sides of the building through holes made in the original façade of the construction. "These connections could weaken the sound insulation of the original façade or could let the air pass into the building, affecting its heating quality," explains Julen Astudillo. "All the tests have been successful. This means that the whole demonstration using such an innovative façade can be insured by insurance companies in the whole Spain, for the future use on any other Spanish building," says Serge Galant, C.E.O. of Technofi, a science and technology company, located in Sophia Antipolis, France. He is defining an insurance policy for the field trial of the MeeFS innovation in Spain. However, the system needs to meet cost effectiveness requirements in order to penetrate the competitive construction market. "The full-scale demonstration of the MeeFS façade technology fits in with a new business trend, already used by energy service companies (ESCOs)," explains Galant. ESCOs are more often companies that belong to large energy utility groups. They offer long-term contracts of 20 years or more, covering the risk of a full refurbishment against the payment by the owners of a fixed yearly energy bill which corresponds to the reduced energy needs of the refurbished buildings. The project's researchers admit that their system is neither simple, nor cheap. Yet Julen Astudillo is optimistic about the possibilities of the façade having a good return on investment.

This present chapter aims at positioning storage technologies with respect to the current market designs and regulatory schemes, thus investigating ways and means to ease a cost-effective, market-based deployment and operation, with a special attention paid to Europe. This approach should help in avoiding any a priori opinion favouring long-term investments in storage systems. Indeed, future electricity systems will face challenges such as significant increases in variability and intermittency of generation, the rapid growth of distributed energy/power resources including distributed generation, the penetration of electric vehicles and controllable demand and deployment of smart appliances enabling active demand response. A growing interplay between transmission and distribution levels will then be necessary. Future power systems will therefore need a properly designed, market-based system architecture allowing for decarbonisation while ensuring system reliability and security of supply. Electricity storage is one among several options to provide system services such as capacity firming, back-up capacity, voltage and frequency regulation. Implementing electricity storage solutions thus requires an in-depth understanding of possible services that electricity storage can meet, along with several other grid and generation- and demand-side assets. © Springer-Verlag London Limited 2013.

This chapter introduces the main trends which drive present and future changes of the transmission systems, as well as the new opportunities raised by advanced transmission technologies. It then details a case study for Europe: a TSO-targeted technology road map for the integration of promising innovative power transmission technologies into the Pan-European power system from 2020 to 2040. This time frame will be critical for the evolution of the European power system towards a low-carbon economy by 2050. In conclusion, some limitations of the described approach are discussed and routes to improve the present road-mapping results are hinted at. The removal of these limitations will be the subject of new key European research projects to be developed in the coming years. © Springer-Verlag London Limited 2013.
