Connection to the grid
Updated: 08.02.2019
Plant operators are contractually entitled to be connected to the grid by the grid operator. The grid operator is obliged to enter into these agreements of which the essential contents are defined by law (Art. 112 Arrêté du 19 décembre 2002). Prior to entering into an agreement, the grid user shall submit an application for connection (demande de raccordement) to the grid operator. The claim for grid connection arises at the date of the conclusion of the agreement.
Every plant operator or grid user that meets the technical conditions of a so-called "utilisateur du réseau“ is entitled to connection (Art. 45-78 Arrêté du 19 décembre 2002).
The obligated party is the grid operator (Art. 3-9 Arrêté du 19 décembre 2002).
Brussels
In the Brussels-Capital region, each application for a connection to the electricity distribution grid shall be submitted to the Distribution System Operator (Art. 73 Arrêté du 23 mai 2014). The installations are connected to the low voltage or middle voltage grid according to their capacity. Installations with a grid connection capacity:
- up to 56 kVA are connected to the low voltage grid
- between 56 and 250 kVA can be connected either to the low or to the middle voltage grid, depending on the connection proposal of the grid operator
- larger than 250 kVA are connected to the middle voltage grid (Art. 73, Arrêté du 23 mai 2014).
Each connection to the grid shall meet the technical requirements C2/112 and C1/107 of SYNERGRID (Art. 79, Arrêté du 23 mai 2014). Moreover, RES installations shall comply with the additional technical requirements C 10/11 of SYNERGRID (Art. 91, Arrêté du 23 mai 2014).
Flanders
Plant operators have to apply for grid connection to the distribution grid operator. Two different procedures apply depending on the access capacity: simple access procedure for an access capacity less than 25 kVA (Art. III.3.2.3. Technical Regulation) and access procedure of installations with higher capacities requiring a feasibility study (Art. III.3.2.5. Technical Regulation). Moreover, there is a procedure for temporary grid connection (Art. III.3.2.4. Technical Regulation). During application preferential status is granted to renewable energy. The plant operator has to cover a fixed amount of costs that is determined by law, any excess costs are covered by the distribution grid operator.
Wallonia
According to the Walloon Energy Commission CWaPE, each application for a connection to the electricity distribution grid shall be submitted to the Distribution System Operator appointed to the area to which the plant operator belongs. Connection applications for installations with a capacity over 25 MVA shall be submitted to the Transmission System Operator Elia. Each connection to the grid shall meet the technical requirements C2/112 and C1/107 of SYNERGRID (Art. 52 Arrêté du 3 mars 2011). Each natural or moral person has the right to apply for a grid connection (Art. 77 Arrêté du 3 mars 2011).
Procedure
Process flow | The distribution grid operator operates on the national level on grids with a voltage of 150 kV to 380 kV. The following procedure applies therefore to all regions:
Prior to submitting an application for connection, a plant operator may request the grid operator to conduct a benchmark study (Art. 79 Arrêté du 19 décembre 2002). This benchmark study shall include a cost estimate for connection (Art. 88 and 80 Arrêté du 19 décembre 2002). The costs of the benchmark study shall be borne by the applicant. Where technically feasible, the grid operator is obliged to give priority to renewable energy plants with a capacity of up to 25 MW when conducting benchmark studies or processing applications for connection (Art. 79 §2 and 100 Arrêté du 19 décembre 2002). Brussels Installations to be connected to the low voltage distribution grid: The submission of a grid connection application for the low voltage grid does not request the prior realisation of an orientation or a detailed study (Art. 116, Arrêté du 23 mai 2014). Installations to be connected to the middle voltage distribution grid: In order to obtain a preliminary grid connection project informing about the feasibility and the technical details of the grid connection of the installation, the applicant has the possibility to ask the grid operator for an “orientation study” (Art. 94-96, Arrêté du 23 mai 2014). Moreover, the application for a grid connection requires the realisation by the grid operator of a detailed study (étude de détail) paid for by the applicant (Art. 94-95 and 102, Arrêté du 23 mai 2014). Flanders Every grid operator is obliged to publish tariffs and conditions for grid access and usage (Art. 4.1.18 §2 Energy Decree). Access can be denied on the basis of insufficient capacity, safety and technical reasons as well as non-eligibility (Art. 4.1.18 § 2. Energy Decree). A written reasoning thereof has to be sent to the applicant (Art. 4.1.18 §3 Energy Decree). Conditions on cutting or interrupting access are laid out in Art. 4.1.18 §3 containing emergency situations etc. The application of access contains the applicant’s identity and contact details, ownership relationship to the installation and plant including a floor plan, the actual access capacity and voltage level, technical characteristics of the installation and further information relevant for determining consumption profile (Art. III.3.3.1 §2 Technical Regulation). Generally, one has to differentiate between simple access with an access capacity less than 25 kVA (Art. III.3.2.3. Technical Regulation) and access of installations with higher capacities requiring a feasibility study (Art. III.3.2.5 Technical Regulation). Regarding simple access, the application is handed over to the distribution grid operator via letter, e-mail or the website. Within 5 days, the distribution grid operator has to communicate to the applicant if the application is inadmissible. If not, the grip operator will send the applicant a binding offer (stating conditions and further steps) or a written stated denial within 10 days (Art. III. 3.3.3 - 6 Technical Regulation). Applying for access to capacities < 25 MVA, the application has to be sent to the distribution grid operator of lowest voltage level stating whether an orientation study or detailed study is requested. The costs thereof are published by the distribution grid operator. The orientation study is facultative for high voltage access and not binding to either party (Art. III.3.3.14 Technical Regulation). Costs have to be covered by the applicant. The distribution operator can request further information but has to communicate its decision within 15 days (maximum 30 days if access to voltage > 30kV or access of installation with a capacity higher than 1 MVA) (Art. III.3.3.20 Technical Regulation). The access with study is designed as part of a price offer in line with the regulator‘s policy (Art. III.3.3.15 Technical Regulation). Two procedures are laid out by regulation: an orientation study with preliminary access and a detailed study with design of access. Regarding orientation study with preliminary access, the distribution grid operator has to communicate the admissibility or denial of the application within 15 days (max. 30 days) after a complete application has been received (Art. III.3.3.20 §1 Technical Regulation). The preliminary connection study entails a scheme of the planned connection, technical requirements and an estimation of costs (Art. III.3.3.20 §3 Technical Regulation). Concerning a detailed study with design of access, the distribution grid operator has to communicate the admissibility of the application within 10 days after a complete application has been received in a written form. Within 30 days (max. 50 days), the decision on access or denial is communicated including further steps of implementation. Both procedures give preferential status to renewable energy (Art. III.3.1.20. §4 Technical Regulation). If access capacity is between 250 kVA and 15 MVA, access is established from high voltage grid via the distribution grid operators to the lowest voltage level (Art. III.3.1.3. §3 Technical Regulation). If access capacity is between 15 MVA and 25 MVA, the distribution grid operator can decide on the basis of technical and economic considerations to transfer application to the operator of a higher voltage level (Art. III.3.1.3. §4 Technical Regulation). Wallonia Installations to be connected to the low voltage distribution grid: Each application for grid connection has to be done according to the procedure published by the grid operator on its website (Art. 94 Arrêté du 3 mars 2011).
Installations to be connected to the middle voltage distribution grid: In order to enquire about the feasibility and the technical details of the grid connection of the installation, the applicant has the possibility to ask the grid operator for an “orientation study” (Art. 65 Arrêté du 3 mars 2011). However, before applying for an orientation study, the applicant can obtain a preliminary notice about the connection possibilities of the operator. Moreover, the application for a grid connection requires the realisation by the grid operator of a detailed study (étude de détail) paid for by the applicant (Art. 77 Arrêté du 3 mars 2011). |
