A connection solution study is needed when a consumption, generation or storage site has to be connected to the grid and the technical solution is not yet settled. The typical cases are new consumers and increases in approved capacity. The study is required for photovoltaic parks, storage systems and generation capacity. The network operator can ask for several connection alternatives to be compared before the connection permit (ATR) is issued.
Services
Connection solution studies
We analyse the technical alternatives through which a consumer, a producer or a storage system can be connected to the grid and prepare the technical and economic case for choosing the solution.
ANRE context
In the connection process, the solution study substantiates the technical solution behind the connection permit (ATR). The ANRE regulation covers the connection request, the setting of the solution, the issuing of the ATR, the connection contract, the works and energisation.
In brief
What this service solves
The connection solution study compares the possible connection points and technical alternatives, then substantiates the recommended solution for the connection permit (ATR).
ANRE D1 attestation0.4 kV - 400 kVRomania and the Republic of Moldova
01
Input
We clarify the requested capacity, the operating regime and the possible connection points.
02
Analysis
We model the network and calculate steady-state regime, short-circuit currents, voltage drops and loading.
03
Documentation
We compare the alternatives technically and economically, including reinforcement works where they are needed.
04
Permitting
We prepare the study for the operator and support the technical clarifications.
When it is needed
- A connection solution study is needed when a consumption, generation or storage site has to be connected to the grid and the technical solution is not yet settled.
- The typical cases are new consumers and increases in approved capacity.
- The study is required for photovoltaic parks, storage systems and generation capacity.
- The network operator can ask for several connection alternatives to be compared before the connection permit (ATR) is issued.
Documents to start from
- A connection solution study starts from the connection request and from the client's identification data.
- The requested capacity, the consumption or generation profile and the operating regime are required.
- The site plan and the cadastral data fix the consumption or generation site.
- The data on equipment, inverters, transformers or the storage installation completes the calculation model.
Main deliverables
- The client receives the connection solution study, with the recommended solution and its technical justification.
- The study contains the steady-state regime calculation and the short-circuit currents.
- The connection alternatives are compared technically and economically.
- The conclusion is written as a recommendation for the connection permit (ATR).
Decisions it settles
- The study establishes the optimal connection point.
- It shows which network reinforcement or extension works are required.
- It clarifies the costs, the schedule and the technical conditions that go into the ATR.
