Parallel to the monitoring exercise to track the progress of the R&D Roadmap, extensive interviews have been done within the Grid+Storage project to identify the deployment potential of R&D results.

The achievements of R&D projects may be intermediate results or may call for further research, for further development, or for a demonstration. Sixteen major results have been identified as the most promising ones for short-term deployment by 2020. An indicative timing for deployment is specified. In addition, ENTSO-E is organizing some concrete actions in order to facilitate the deployment of the R&D results.

Innovations Towards Improved Grid Planning Approaches
2016: Modular plan of pan-European grid architectures for 2050

The e-Highway2050 project looked at how the transmission network should evolve in order to reach close to zero emissions in the EU by 2050. Completed at the end 2015, it resulted in a modular development plan for possible electricity highways and options for a complete pan-European grid architecture, based on various future power system scenarios.

ENTSO-E is currently investigating how the project results will be exploited in the 2016 Ten-Year Network Development Plan (TYNDP 2016). More specifically, TYNDP teams have expressed interest in key components, such as the systematic methodology to build 2050 energy scenarios, the methodology to build the equivalent grid model, the methodology for scenario quantification, and the methodology to propose transmission investment needs per scenario.

2018: Towards a probabilistic planning approach

The Garpur project designs a new reliability management approach and criteria for the pan-European electric power system. It covers multiple decision-making contexts and timescales (long-term planning,

mid-term planning, and asset management and short-term planning to real-time operation). It will be applicable for TSOs to implement the Garpur concepts in an off-line environment (grid planning).

Innovation in Transmission Grid Technologies
From 2014: Preventing overload situations in the 220 kV transmission grid

The 220 kV SSSC Device for Power Flow Control project has been successfully completed, and the static synchronous series compensator (rated 47.8 MVAR, 12.5 kV) has been installed in the Spanish 220 kV transmission grid. This technology optimises the utilisation of the existing electricity grid, the final objective being to maximise the integration of generation from renewable energy sources. This is the first ever implementation of such technology in the European transmission system. Further tests will be needed for upscaling to higher voltage levels (300 – 400 kV).

2016: A database of cost and performances of power system technologies

Developed within the e-Highway2050 project, a database of cost and performance over the period 2015–2050 will soon be made freely accessible. It is an asset for further collaborative R&I projects, for grid planning studies, or more generally for any type of studies involving power technologies and their cost and performance trajectories over the period 2015–2050. It will be published on the GridInnovation-on-line platform.

2018: Innovative repowering of AC corridors

Integrating renewable energy sources into the grid implies developing novel network technologies to increase the capacity of the pan-European transmission network and the flexibility of the electricity system.

The results of the Best Paths project will be grouped into a self-standing package for upgrading existing lines. This package will help TSOs to deliver overhead lines that are more compact, have a reduced visual effect, are less demanding regarding the right-of-way (legal right to pass along a specific route through grounds or property belonging to another), able to face fluctuating power profiles, flexible in exploitation (reducing the need for new AC overhead line corridors), and have an affordable life-cycle cost.



This combination of new solutions enhances the current approach to the repowering of AC overhead lines. It will also help TSOs and utilities to keep overhead lines reliable and resilient to future developments of the European energy system (e. g., increased amounts of renewable generation). Finally, novel approaches can be shared and replicated by other TSOs.

2019: Linking offshore wind parks to the mainland

In order to unlock the full potential of Europe’s offshore resources, network infrastructure is urgently required, linking offshore wind parks to onshore grids in different countries. To do so, HVDC technology is a possibility, but the deployment of meshed HVDC offshore grids is currently hindered by the high cost of converter technology, the lack of experience with protection systems and fault clearance components, and immature international regulations and financial instruments.

The Promotion project will overcome these barriers by developing and demonstrating three key technologies, regulatory and financial frameworks and an offshore grid deployment plan for 2020 and beyond. This project not only demonstrates all elements needed to build meshed offshore grids, but also brings together the future workforce in Europe, which has to design, build, and operate a commercial network. The Promotion project will take into account the results of the Best Paths and Twenties projects.

Innovations Towards More Secure and Efficient Management of the Transmission System
From 2012: Wide-Area Monitoring Systems

Wide-area monitoring systems (WAMS) allow the monitoring of transmission system conditions over large areas in view of detecting and counteracting grid instabilities. The WAMS developed and upgraded within the iCoeur project have been implemented and put into operation by several TSOs worldwide. In Europe, WAMS systems have been integrated to some extent by systems of the TSOs in Slovenia, ­Germany, Spain, France, Montenegro, and Serbia.

From 2015: A toolkit for security policy makers

The European electricity grid is a critical infrastructure, which can be exposed to security threats. The Seconomics project delivered a toolkit to security policy makers, helping them to understand their policy alternatives and the potential effects of their decisions. This toolkit has already been adopted by the standard body in CVSS v 3.0 issued in December 2014. The CVSS is a general methodology that is used by several TSOs for evaluating the security of their supervisory control and data acquisition (SCADA) systems.

2018: Tools to cope with increasingly uncertain operating conditions

The iTesla project has delivered several pieces of software forming a new security assessment tool, which is able to cope with increasingly uncertain operating conditions and to take advantage of the growing flexibility of the grid.

After the end of the project, the French TSO, RTE, will build full size (spatial and temporal) use cases that give insight into system security and demonstrate the added value for operators, both in technical and economic terms. This validation should last two years, with the final goal of introducing an industrial version of the toolbox in an operational environment (control room) for preliminary tests by 2018.

The Umbrella project has also delivered a toolbox prototype enabling TSOs to act in a coordinated European target system where regional strategies converge to ensure the best possible use of the European electricity infrastructure. Exploitation of the toolbox is being addressed within the framework of the Transmission System Operator Security Cooperation (TSC). The iTesla and Umbrella projects have cooperated to deliver common recommendations to ENTSO-E.

2018: Towards the digitalisation of existing substations

Within the Smart Substation project, the deployment of the smart substation will allow network operators to better manage congestions, thanks to local optimisation and distributed intelligence, and to host more renewables, such as wind power. The deployment is ongoing, and the substation should be ready for validation by February 2017. The construction of databases for long-term analysis is performed using the latest IT technologies (Internet of things and big data).

2019: Real-time and short-term forecast assessment of operating limits

Funded by the Slovenian TSO, ELES, the Sumo project aimed at developing a novel strategy to improve climate simulations. It has developed a system for real-time and short-term forecast assessment of operating limits. Methods and software have been developed to deal with the highest possible power flows of the transmission line, considering all weather situations. The SUMO system uses different heterogeneous subsystems from different vendors, and the ­results of the calculations are aggregated and are shown in the network control centre by means of the visualisation platform.

Innovations Towards the Integration of Renewables and ­Distributed Resources in the European Electricity Market
2016: Data sharing platform supporting energy efficiency services

The Estfeed data sharing platform provides links to applications allowing organisations and individuals to monitor and manage their energy consumption. It is managed by the Estonian TSO, Elering. It gives wider options to both consumers and businesses (including new types of stakeholders like ESCOs, aggregators, and energy cooperatives) and facilitates the functioning of the energy market. Sharing data on the platform across different countries and regions will enable a better inter-TSO service. The ­European-wide approach gives even more oppor­tunities to market stakeholders to do business and enables consumers to select between even more ­services and service providers.

2017: A numerical platform to test and compare short-term electricity market design options

The Optimate project (2009–2012) has delivered a prototype simulation tool able to simulate different market architecture options in the context of high ­integration of renewable energy sources. The initial prototype, focused on the day-ahead stage, is currently being upgraded by the French TSO RTE. It now has a broader functional scope with intraday and real-time modules as well as increased robustness and ­improved computation time. An industrial version of the simulator should be delivered by the end of 2016.
