WindEurope: What needs to be done with the regulatory framework to develop hybrid stations and exploit storage

Posted on August 12, 2019

EU Member States should fully integrate the hybrid units into their regulatory framework, as WindEurope estimates in a recent report, while pointing out the requirements for their development as well as the specificities of their combination with energy storage.

WindEurope's first recommendation is that in order to address licensing and development issues, such as measuring and integrating storage, European states must fully integrate hybrid plants into their regulatory status and procedures and requirements must be formalized.

He stresses that "optimizing the measurement in hybrids will drastically reduce administrative needs in terms of cost and time. In addition, it will alleviate financial and regulatory uncertainty for investors.

Having a metering system at the dock with additional virtual metering points inside the unit allows for the measurement of total production and consumption and the transparent measurement of the production of individual technologies. In turn, this provides the investor with transparency about their expected earnings and stimulates the development of hybrids. In addition, it enhances the prospects of digital services and solutions ".

Apart from the above, one of the findings of WindEurope has to do with the use of energy storage in hybrid plants, as it considers that in Europe there is an incentive to prioritize RES power rather than participation in storage in hybrid plants.

As he typically states, "adding storage to an existing hybrid power station may jeopardize subsidies in some cases (suspected of" gray "energy provided by the unit rather than" green "). Some national regulations address this issue by setting a limit on the maximum power that can be stored by the network, while others, such as Greece, set a maximum ratio of total RES power to storage power. Companies that develop hybrids are therefore motivated to prioritize renewables rather than storing them. "

For its part, WindEurope believes that the size of storage should be calculated for each unit based on market design and the opportunities presented, that is, parameters such as system needs, station design, cuts, cost and technical features. In any case, it considers that the size of storage should not be limited by adjustments.

The connector also estimates that the energy stored by the grid should not be limited unless the station is included in an aid scheme. "Wholesale prices should direct charging when low, ensuring that systematic charging enhances the system. An approved and transparent metering procedure at national level can ensure the origin of green energy. "

Lastly, WindEurope notes that the amount of energy dissipated in the network by a hybrid storage unit should be treated like the one with batteries and avoid double taxation.
