All producers, developers, or operators, whose installation is or needs to be connected to the public distribution network (HTA) or transport network (HTB) for electricity, are responsible for ensuring that the installation complies with the technical requirements of the Decree n°2008-386 of 23 April 2008 and the decrees of 23 April 2008, which specify the performance standards to be met.
Scope and Consequences of the Compliance Requirement
These requirements are incorporated into the various contracts signed with the network manager, including the technical and financial proposal and the connection agreement. If these obligations are not met, your injection can be interrupted by the network manager, thereby suspending the collection of electricity sales revenue (at the obligatory purchase rate or market price).
To prevent this risk of interruption, you should, during the planning phase (in project phase), but also during the operation phase, maintain these performance levels, under the supervision of the network manager, which occurs particularly when putting the installation into operation or returning it to service.
What does the compliance and performance that your installation is subject to consist of?
The installation must therefore guarantee the conformity of its decoupling protection, a maximum level of short-circuit input, the compatibility of the protection system with that of the network, the ability to withstand exceptional frequency and voltage regimes at the delivery point, the ability to withstand dips and voltage fluctuations, respect for the maximum level of current harmonics, etc.
Compliance and performance apply to all installations connected to public networks, without distinction according to the primary energy source (renewable or conventional, wind or photovoltaic, etc.), size, or location. However, the precise list and scope of the tests, studies, calculations, certifications, and inspections required depend on the connection network (transport or distribution) and the situation of your installation: initial commissioning, re-commissioning after shutdown, re-commissioning after substantial modification, periodic checks during the operating period, after a malfunction.
How to best fulfill the regulatory and contractual obligations that you are responsible for?
Firstly, you can maintain a conformance file that will allow you to archive all documents related to the initial commissioning, restart after shutdown, restart after a substantial modification, periodic checks during the operating period, and check after a malfunction.
At all these key moments, you will have to carry out certain electrical studies and calculations (optional simulations) yourself and under your sole responsibility, the list of which is set by regulation. These electrical studies and calculations must comply with current standards and rely on manufacturer data and methods developed by the relevant network manager.
Furthermore, you will need to obtain, analyze and verify the technical information (equivalent diagrams, electrical characteristics) from the manufacturers of the equipment making up your installation (inverters, turbines, generators, transformers, cabinets, cables, panels, etc.) and from the network manager himself (analysis and processing of metering data).
Finally, you will need to appoint one or several duly authorized inspection organization(s) to carry out the inventories, tests, trials, and verifications required by the regulations.
Monitoring the compliance and performance of your installation therefore requires skills in project management and electrical engineering.
Zelya Energy supports you by facilitating the compliance and performance control of your installation.
