Connection

Grid Capacity: simulate your connection to the distribution network, in just a few minutes

Grid connection is an operational and financial risk factor for renewable energy project developers.

Control the risk with Grid Capacity!

“I have a good potential site for 3 MW of photovoltaics, but it's a bit far from the grid... How much will it cost to connect it?”"I've found land to develop a 3MW project and want to free myself from the risks of connection""My 4MW project is falling through because of the connection costs, and I'd like to look at the connection options to propose an alternative solution."

Grid Capacity:
The challenges of POWER network connection

Prospect effectively by targeting favorable areas from a grid perspective

Arbitrate between favourable and risky opportunities in terms of connection costs and economic viability

Improve cost estimations when responding to tender

Optimize your grid connection requests to maximize the return on investment of the installation:

module and inverter sizing, use of reactive power regulation, etc.

Find out more about the local characteristics of the grid in order to better understand the Distribution System Operator's connection proposals and facilitate exchanges.
