Are microgrids legal
Microgrids are decentralised electricity systems that can operate independently of the main electricity network, and which have the potential to contribute to the energy transition towards a more sustainable en. [pdf]FAQS about Are microgrids legal
Are microgrids legal in the EU?
In the EU, various Member States (MS) have implemented microgrids to test the system, such as the Netherlands, Germany, and Greece.1 However, EU law lacks a clear legal definition and regulation of microgrids.
Can microgrids be regulated?
If the existing rules in EU energy law allow for some flexibility to include electricity household consumers under the provisions of Closed Distribution Systems and allow for Citizens Energy Communities to manage part of the distribution system, the legal framework does offer possibilities to regulate microgrids.
Are microgrids legal or technical?
Technical and legal definitions sometimes differ. Indeed, technical definitions, albeit close to reality, may prove too complex to be intelligible to all and to be efficiently applied by the courts. That is why when a legal definition for a technical concept is needed, a specific reflection is mandatory, and microgrids are no exception.
Should microgrid users be incorporated into the legal framework?
Considering microgrid consumers as active customers who are allowed to manage their distribution system provides the first step to integrating microgrid users into the legal framework. However, the risks of combining the roles of consumer and investor in an electricity system must be considered.
