An impact study is needed when a generation, consumption or storage project can change the way the network it connects to operates. The study is required for large generation or storage capacities. It is needed for projects that call on the 110 kV, 220 kV or 400 kV networks. Investors use it to document the technical bankability of the asset.
Services
Impact studies
We assess the effects a project has on the distribution or transmission network, focusing on capacity, stability, operating restrictions and compatibility with the regional development of the network.
ANRE context
For large generation, consumption or storage projects, the impact analysis helps in understanding the effects on the network and the works required. For producers, the current framework also includes rules on capacity allocation and financial guarantees.
In brief
What this service solves
An impact study shows how a project influences the electrical network: power flows, short-circuit levels, congestion, reinforcement works and operating limitations.
ANRE D1 attestation0.4 kV - 400 kVRomania and the Republic of Moldova
01
Input
We define the operating scenarios and the injection into or withdrawal from the network.
02
Analysis
We analyse power flows, short-circuit levels, limitations and regional influences.
03
Documentation
We identify the reinforcement works and the congestion risks.
04
Permitting
We prepare the conclusions for the operator, the investor and the lender.
When it is needed
- An impact study is needed when a generation, consumption or storage project can change the way the network it connects to operates.
- The study is required for large generation or storage capacities.
- It is needed for projects that call on the 110 kV, 220 kV or 400 kV networks.
- Investors use it to document the technical bankability of the asset.
Documents to start from
- An impact study starts from the installed capacity and from the technology profile of the project.
- The available network data and the possible connection points are required.
- The proposed single-line diagram describes the configuration of the installation.
- The investment schedule and the phasing assumptions fix the scenarios analysed.
Main deliverables
- The client receives the grid impact study, with the calculated effects of the project.
- The study describes the operating scenarios and the limitations that follow from them.
- The reinforcement works required are analysed separately.
- The technical conclusions are written for the investment decision.
Decisions it settles
- The study shows how much capacity is available in the project area.
- It identifies the congestion risks and the operating restrictions.
- It states which additional investments may condition the connection.
