Ensuring a level playing field

​​​​​​​​​​​​​Most energy conversion technologies have not yet reached an efficient scale. They are likely to develop with an effective price signal, investments in research and development, and a system integrated network planning and operation.

Decarbonised gases, electrolysers, demand side response mechanisms and increased flexibility are likely to develop with more distributed generation and integrated market signals. 

The energy efficiency-first principle, together with the role of energy storage (thermal, gas, electricity, chemical) and the need for an improved access to and operation of the energy flexibility mechanism, are key elements to reach the decarbonisation and other energy system integration targets.

From a regulatory perspective, all technologies must be guaranteed a level playing field, so they can compete on the merits. Any obstacles or barriers to their equal treatment should be identified and removed, following an integrated energy system perspective.
