Differences between Developing a Solar Plant and a Wind Plant

The Global Electricity Review 2022 reports that solar and wind provided more than 10% of global electricity in 2021. The enhanced technical operations and lowered cost are the driving forces behind the success of these renewables. More development of these renewable energy sources is becoming alluring, particularly in areas where natural conditions are favorable.

There are typical steps for developing a solar plant or wind plant, but the specifics can differ. That applies to solar plants and wind plants. In our continued coverage of renewable energy assets, we compare the development of these two plants.

Phases of Renewable Energy Projects

The stages of any renewable energy project can be summarized as the project stage, exploitation stage, and end-of-life stage. Project development of a renewable energy project typically involves substantial planning and organization regarding variables such as raw materials, duties for the team, and the budget. There’s also a timeline and goals to keep in mind. To execute the project perfectly, prospecting is essential, as is the permitting and licensing process.

Regardless of the roadmap that developing a solar plant follows, here are the key phases that the project development follows:

  • Site identification
  • Pre-feasibility study
  • Feasibility study
  • Financing and contracting
  • Detailed design
  • Plant construction
  • Commissioning

For a wind plant development, the process can be equally long and treacherous, incorporating the assessment of economic, political, environmental, and technical elements to the last detail. Like the solar plant project, the development can be divided into several phases as outlined here:

  • Screening
  • Feasibility study
  • Development
  • Contractual commitment
  • Project delivery
  • Project operation and maintenance

A Summarized Comparison of Solar and Wind Plants

For a renewable energy project to progress, prospect work has to be done, followed by authorizations and permits. In other words, there are different phases to the development of a plant. Below are a few elements to compare the execution of these plants.

Timeline 

  • A concrete evaluation and execution of the project can take months to complete, but this depends a lot on the project’s complexity. 
  • Like the wind plant, solar plant development duration depends on many factors. 
  • The project can take up to four years to complete. 

Challenges 

  • Extensive environmental studies to determine the wind potential in an area can take long
  • Need to place the wind farm close to transmission lines to minimize transmission costs
  • Permitting process and sales agreement economics can be expensive  
  • Not suitable in urban areas
  • Infrastructural challenges concerning the grid
  • A lot of potential legal issues to cover - energy performance certificate (EPC), maintenance agreements, grid connections, acquisition of rights for cable route, etc. 
  • Land assessment can be lengthy and complex
  • Solar panels must face the sun

Expertise required 

  • Social impact specialist 
  • Atmospheric scientist 
  • Project designer 
  • Specialist in environmental impact assessment 
  • Lawyer to take care of PPA, financing, grid connection, permits, etc. 
  • Public relations officer
  • Land development advisor etc. 
  • Resource assessment specialist
  • Project manager/engineer
  • Atmospheric Scientist
  • Meteorologist 
  • Lawyer 
  • Public relations officer

Activities undertaken 

  • During the development phase, a wind plant project involves important activities that seek to minimize risk during project execution. 
  • There will be a LiDAR application for accurate wind data, environmental study, geotechnical activities, and special permitting. 
  • The project developer creates the project development plan indicating resources available and the goals. 
  • Site visits and collection of utility data to have an idea of the amount of sunlight on the sites. Identification of economic, natural, and political factors that may affect the project. Contract signing. 

Cost of development 


  • Developing competitive onshore wind power projects cost as little as USD 0.030/kWh, while offshore projects required about USD 0.115/kWh. A 1MW plant would therefore cost 
  • The average cost of developing a wind turbine in the US as of 2018 was $1,382 per kW. 
  • The cost of development can vary because of factors such as cost of installation, cost of solar modules, location, and availability of sunlight hours.  

Agreements and permits 

Some of the permits to expect for a wind project:

  • Land use permit
  • Approval for grid connection
  • Wildlife protection permit
  • Zoning permits
  •  

Permits for solar energy development include but are not limited to the following:

  • Environmental permits
  • Land use agreements
  • Access agreements
  • Grid connection
  • Operator licenses
  • Construction permits
  • Social impact 
  • Land lease agreements

Conclusion


There are some differences between developing a solar plant and a wind plant, but of significance is for developers to know that there are means of ensuring project success.

Using asset management software, which involves the transformation of raw data into essential business insights, has proven instrumental for numerous projects globally. QBI Solutions is committed along this line and has covered at least 1,100 renewable energy assets globally to date.
