PRE-FEASIBILITY AND PROSPECTING

The goal of prefeasibility analysis is to determine regions that have the potential for feasible wind projects. It uses publicly available wind resource maps along with considerations such as tariffs, land availability, licensing process, transmission, logistics, cost of project, and others. Prospecting involves site visits to the regions that meet the prefeasibility requirement in order to collect additional data about terrain, vegetation, landownership, and other factors. The outcome of prospecting is a shortlist of regions with the highest prospects and locations for wind measurement in these regions.

WIND RESOURCE ASSESSMENT (WRA)

Determines the future of a project.  WRA is the quantification of wind resources to compute parameters such as average wind speed, average wind energy density, and the average Annual Energy Production (AEP) of a proposed wind power plant. A preliminary WRA is started in the previous activity. The bulk of the activities in this phase are wind measurement, AEP estimation based on wind flow modeling, AEP estimation based on computational fluid dynamics modeling for complex terrain, and estimation of loss and uncertainty.

PROJECT SITING

Project siting encompasses all the activities that precede construction, such as Environmental Impact Assessment (EIA), obstruction to aviation airspace analysis, interference with radar and telecommunication  analysis, visual impact assessment, site planning and engineering, logistics planning, grid interconnection, and permitting and licensing. This activity may occur in parallel with the WRA step.

POWER PURCHASE AGREEMENT (PPA) AND FINANCING FACILITATION

The focus of this activity is on the financial aspects of a wind project. Power Purchase Agreement (PPA) negotiation with a purchasing utility is the first step, followed by agreements with equity and debt financiers. This activity occurs after the WRA and project siting activities.

ENGINEERING PROCUREMENT AND CONSTRUCTION (EPC) CONTRACTING

This activity starts with the selection of an EPC contractor and selection of turbines for the project. In this activity, detailed project plans are created along with detailed engineering of the foundation, roads, collection system, substation, grid interconnection, logistics, and others.

CONSTRUCTION, INSTALLATION AND COMMISSIONING

In this activity, the wind power plant site is prepared, roads are constructed, foundations of turbines are constructed, towers are erected, the nacelle and rotor are lifted, and the turbines are commissioned.
