A feasibility assessment for wind energy can follow on from a pre-feasibility assessment, or may be the first step in evaluating a site’s potential for wind energy production. Its aim is to enable the project stakeholders to confidently make a decision on the projects future.
Unlike a pre-feasibility study, a feasibility study is likely to include some level of local site assessment. Typically wind direction and wind speeds are measured on site over a year or more, and these are then compared to local long term meteorological data.
A feasibility study will go into more depth than a pre-feasibility study, but not into the level of detail required for a detailed design.
Some of the tasks that may be undertaken at this stage include;
Site survey and wind resource assessment
This involves physically inspecting the site to assess the topography, nearby obstructions, and constraints that may affect turbine siting. At this stage local electricity distribution infrastructure is identified which will assist with the review of grid connection requirements.
We will obtain local long term wind data where available, which we use to help with turbine positioning and annual energy production estimates.
We can start on site wind monitoring at this stage if required, as local site data is generally required over a period of a year or more.
Preliminary Site Map
From the site survey and site constraints (such as noise and separation requirements), we produce a map of where turbines can be placed.
Check the route to bring materials to site, including any bridges and load limits, and tight corners for long loads.
After the site survey and assessment, we work out what available options exist that will suit the site and meet the project requirements for the turbine and rotor and the tower height.
Determine closest electricity network which is available for connection, and the most appropriate way to connect to the network. We will get in touch with the local distribution authority and obtain a budget estimate to connect to the network.
As part of the planning checks, we will assist with the following;
Economics and Performance
Suno will estimate the annual energy production for the system, including an estimate for downtime.
We will produce a budget cost estimate for the project which will include estimates for the following;
The financial performance of the project shows the initial capital, the break even point and annual income expected afterwards. This estimate is made up of the budget project estimate, and also includes the operation and maintenance costs, the costs of finance and insurance, and the electricity export rates as well as any subsidies over the expected project life.
