Electrical System

The integration of renewable energies and the development of electricity markets require the in-depth adaptation of networks and regional cooperation which necessitates an appropriate regulatory framework to ensure the success of these transformations.

Regulation of the Electricity System

Our teams can assist the relevant authorities (energy ministries, regulators, network operators, etc.) in designing and developing the regulatory framework for the electricity sector to adapt it to new conditions.

Drafting and Implementing Grid Codes

Regulatory and technological developments in electricity networks require the implementation and adaptation of grid codes, including connection conditions, standard contracts, the provision of system services, and the management of interconnections. Thanks to its worldwide experience, RTE International is able to offer tailored solutions for drafting grid codes in consultation with stakeholders and adapting them to the regulatory framework in force.

Connection of Renewable Energies

Future grid users need clear, non-discriminatory access rules to optimize their investments. In collaboration with grid operators, our teams propose a suitable framework for:
  • Connection procedures and financing
  • Construction specifications
  • Access tariffs
  • Participation in system services
Our experts can also lead the public consultations needed to establish these rules.

Renewable energy connection plans

Electricity companies must draw up and implement the generation and network development programme. They must identify the need to renew and optimise their transmission assets, while liaising with the authorities in charge of energy (ministries, regulators) on a sustainable plan that includes financing requirements. We carry out long-term planning studies and help optimise processes, training, tools, and methods for multi-year development programmes.

Renewable energy connection plans

In addition to network development programmes, operators need to plan capacity for new renewable energy installations. Our teams can help you:
  • The capacity of your networks
  • The plan to strengthen transport infrastructure
  • The establishment of renewable production forecasting systems as well as supervision and action adapted to the challenges of intermittency
  • The integration of innovative network systems (storage, FACTS) to ensure network resilience.
  • Economic studies
  • Adequacy studies

Economic studies

The electricity system must constantly ensure a balance between generation and consumption. Adequacy studies ensure this balance in the short and long term. Our teams carry out various studies on:

  • Consumption trends, including energy-saving measures and electric mobility
  • Simulations of climatic and production contingencies
  • Modelling the operation of production units

These studies will lead to recommendations on the need for investment in new means of production.

Storage

Battery storage systems can meet a variety of needs. We carry out technical and economic studies to identify the storage needs of your electricity transmission system, taking into account the role of renewable energies and the flexibility required due to the increase in intermittent production capacity.

Market development. Reserves, system services and balancing

Generation facilities provide network operators with the services they need to ensure the stability of the electricity system. Developing market mechanisms for these services can significantly reduce costs. Our teams can help you define the following:

  • The operator's needs and the characteristics of the products required
  • Transparent and non-discriminatory participation rules for network users
  • Terms of remuneration and compensation mechanisms
  • Control systems based on IT monitoring tools
  • Corresponding model contracts

Development of demand-side management (DSM)

The participation of industrial consumers in the electricity market offers significant benefits. By allowing industries to offer frequency tuning capabilities, this creates a “win-win” scenario:The network operator improves stability and strengthens flexibility capabilities, while electro-intensive industries (steel, petrochemicals, paper, etc.) generate additional income from their current operations. This also helps reduce CO2 emissions by avoiding start-up of power plants.France has opened up all its national market structures to all consumers, including those connected to the distribution networks, making it the leading country in Europe in this area. RTE mobilised up to 1 GW of load shedding in 2018 through its balancing mechanism. Drawing on its expertise in European load shedding, RTE International can help you identify potential load shedding opportunities as well as set up the appropriate mechanisms.

Power system operation

The management of your electricity transmission networks is becoming increasingly complex as you ensure the supply-demand balance and the safety of the electrical system while integrating renewable energies on a large scale. Drawing on its French expertise, RTE international is able to offer a comprehensive range of services to support you in operating your electricity network.

Support for Network Operations: Evolution of the Organization

The challenges of operating the electricity network are evolving with changes in its structure and the increasing adoption of new technologies in electricity control centers. RTE international can assist you in designing and implementing an organizational structure adapted to both current and future challenges.

Implementation of Operating Rules and Procedures

The goal of operating the electricity transmission network to ensure supply to customers while respecting the limits of electrical installations and guaranteeing safety. RTE International can help you establish operating rules and procedures tailored to your network, ensuring that your corporate objectives are met.

Studies

  • Studies of Constraints
  • Network Defence and Restoration Plan
  • Voltage Studies
  • Short-Circuit Power Studies
  • Protection Plan Studies

Reduction of Technical Losses

We conduct diagnostics and propose recommendations to reduce Joule losses on a long-term basis through appropriate investments, thereby helping to lower greenhouse gas emissions and network operating costs.

Construction of Electricity Dispatching Centres: Engineering of Electricity Dispatching

Electricity dispatching centers centralize key information for operating the electricity system, enabling its supervision and control. Modern information systems facilitate rapid decision-making. RTE international can assist the assessment of feasibility, designing specifications, and constructing modern dispatching centers, offering the best communication and control tools (SCADA, EMS, MMS) to address future challenges.
