Renewable Energy Systems – Wind Power Plants (WPPs)
Wind power plants (WPPs) hold a strategic position within renewable energy investments due to their high production potential and long-term energy cost advantages. However, success in WPP projects is determined not only by turbine selection but also by the accuracy of field data, infrastructure engineering, logistics planning, grid connection suitability, and commissioning discipline. 2G Construction & Energy manages the entire process from exploration to implementation, commissioning to maintenance and operation in WPP projects, ensuring the safe and sustainable realization of the investment.
What is a Wind Power Plant (WPP)?
A WPP is a production facility that converts the kinetic energy of the wind into electrical energy through turbines. The energy produced is transmitted to the grid through turbine-based systems, the medium voltage (MV) collection network, transformers, and switchgear equipment. The fundamental criteria affecting production in WPP projects are: Wind regime (speed, direction, turbulence), terrain topography, micro-siting, and grid connection conditions are key factors.
2G Construction & Energy's Scope of Services for Wind Power Plants
1) Site Survey and Preliminary Assessment
In wind power plant projects, the right decision starts with the right site. Wind measurement data, terrain conditions, access roads, soil structure, and connection points are technically analyzed.
At this stage:
Site survey and infrastructure needs analysis
Determination of road-platform-drainage requirements
Framing of MV collection network and connection scenarios
Preliminary planning of construction and electrical works
are carried out.
2) Design and Implementation Engineering
One of the most critical issues in wind power plants is the correct design of the turbine site infrastructure. Platform elevations, drainage, foundation approach, cable routes, and switchgear/transformer integration are considered within the overall project.
Within the scope of the project:
Site infrastructure plan according to turbine locations
Road route, turning radii and suitability for heavy transport
Platform, drainage and site layout design
MV cable route, splice rooms and protection approach
Integration design with transformer-switchgear facilities
are created.
3) Site Implementation (Construction + Electrical Infrastructure)
Site implementation in wind power projects is a highly disciplined process where time, quality, and safety are managed simultaneously. Planning is critical, especially due to heavy equipment transportation, challenging terrain, and weather conditions.
The implementation includes:
Construction of access roads, platforms, and site arrangements
Foundation construction and quality control processes (according to project scope)
MV collection network cable laying, splicing, and termination works
Transformer/switchyard connections and electrical infrastructure installations
Grounding and lightning protection systems
Labeling, site standardization, and occupational safety practices
are carried out.
4) Testing and Commissioning
The commissioning phase involves verifying that the turbine-collection network-transformer-switchyard chain functions correctly as a whole. Measurements, checks, and documentation are essential for a safe transition to operation.
At this stage (depending on the project scope):
Grounding measurements and continuity checks
MV cable tests and termination verifications
Protection-control compatibility and field checks
Energization scenario and safe commissioning steps
Commissioning reporting and delivery documents
are completed.
5) Maintenance and Operation (O&M) Support
Maintaining performance in renewable energy projects is possible through planned maintenance, field checks, and an operational approach that reduces the risk of failure. The healthy operation of MV infrastructure and switchgear/transformer facilities, as well as turbine production, determines production continuity.
Within the scope of O&M:
Periodic checks of MV infrastructure and field connections
Checking of grounding and lightning protection systems
Preventive maintenance approach for field equipment
Reporting and improvement actions
are presented.
Critical Points Determining Success in Renewable Energy Projects
Site logistics and heavy transport plan: If the road-platform design is incorrect, the installation time will be extended.
Ground and foundation approach: Long-term operational safety begins here.
MV collection network quality: Cable splices, termination, and protection approach affect production continuity.
Grounding & lightning protection: Critical for the protection of turbines and site equipment.
Commissioning discipline: Testing-measurement-documentation catches faults before commissioning.

Frequently Asked Questions
Is the turbine or the site the most important issue in Renewable Energy Projects?
The turbine is critical, but if the site infrastructure (roads, platform, MV collection network, grounding) is not correct, installation and operation performance will decrease.
Why is commissioning a wind power plant a difficult process? Because the turbine-MV network-transformer-switchgear chain works together. Each link needs to be tested and recorded.
Is maintenance only done for the turbine?
No. The MV cable infrastructure, splice points, switchgear/transformer installations, grounding, and lightning protection systems also require regular checks.
