The entity responsible for maintaining the plant when it is operation and optimising output
Leading Operations & Maintenance contractors
The leading O&M contractors linked to projects on the Wiki-Solar Database are shown below. This list is based on the figures available in Q3-2020.
What is an O&M contractor?
The Operations and Maintenance contractor is appointed by the owner to oversee the technical operation of the plant.
This includes routine maintenance and cleaning, and whatever unscheduled fault finding may be required in order to optimise the output of the installation.
Because the EPC contractor has been responsible for the detailed design and construction, it is often the party best able to continue into the operational phase, and many EPC contractors go on to under-take the operation and maintenance role. Addition-ally a number of specialist independent O&M contractors have emerged
Depending on the size and complexity of the project the O&M role may require permanent onsite staff; or may be fulfilled remotely with periodic site visits.
Basis of the data used
The data used for the analysis and the table on the left is derived from operating projects of 4MWAC+ on the Wiki-Solar Database, according to these criteria.
The O&Mcontractor is known for some, but not all, of the projects on Wiki-Solar's database. Therefore, as noted below the table some figures will be under-stated. However, several of the leading participants confirm details of their portfolio to Wiki-Solar (and you can too - see the bottom left of this page).
Some contractors listed also fulfil other roles in utility-scale projects, and many are also EPC contractors. Any figures quoted here apply only to their O&M activities. Where companies have maps, however, these will show all their projects.
