X-FLEX: Integrated energy solutions and new market mechanisms for an eXtended FLEXibility of the European grid

X-FLEX project proposes a set of efficient, cost-effective, integrated solutions that will facilitate the optimum combination of decentralised flexibility assets, both on the generation (DER) side and on the demand side (V2G, power-to-heat/cold/gas, batteries, demand response), enabling all parties, including final prosumers, to offer their flexibility in the market creating benefits to all the actors in the smart grid value chain.

X-FLEX will develop 4 complementary products that will offer services to all the energy stakeholders:

  • SERVIFLEX tool – Integrated flexibility management tool
  • GRIDFLEX tool – Advanced tools for automatic control and observability
  • MARKETFLEX tool – Market platform and new market mechanisms
  • X-FLEX platform – Flexible and scalable integrated platform

These X-FLEX project solutions will be tested in real conditions at 4 pilot sites in 3 EU Member states (Bulgaria, Slovenia and Greece), with different needs and socioeconomic and technological boundaries, involving multiple existing flexibility assets (batteries, power to heat/cold, V2G and other storage solutions) and all complementary actors of the energy network (DSO, TSO, microgrid operator, utilities, flexibility providers, local communities).
