Operation and Maintenance (O&M) Service of Solar Power Plant
A professional Operation & Maintenance (O&M) service package ensures that the photovoltaic system will maintain high levels of technical and consequently economic performance over its lifetime. Currently, it is widely acknowledged by all stakeholders that high quality O&M services mitigate the potential risks, improve the levelised cost of electricity (LCOE) and Power Purchase agreement (PPa) prices and positively impact the return on investment (ROI).
I. What is O&M service?
O&M service stands for Operations & Maintenance - Operation and maintenance of a solar power plant after it is put into operation to ensure its continuous, safe and efficient operation, specifically:
- Operations service provider in charge of monitoring, supervision and control of the PV power plant, coordination of maintenance activities.
- Maintenance service provider carrying out maintenance activities.
II. Roles and responsibilities by different stakeholders in the field of O&M
Figure 1 on the following page attempts to classify and distribute the responsibilities among the different stakeholders and, in particular, among the asset Manager (asset management), the O&M Contractor (Operation & Maintenance) and the EPC Contractor (Engineering, Procurement, Construction)
In general, the O&M Contractor will have a more technical role (energy output optimisation) and the asset Manager will undertake more commercial and administrative responsibilities (financial optimisation). The technical aspects of asset Management are called technical asset Management, a role that is often assumed by the O&M Contractor.
As opposed to the first version of the Best Practices Guidelines, this version handles technical asset Management as part of the core roles that can be provided by the O&M Contractor and thus dedicates a standalone Chapter to technical asset Management.
Note: The responsibilities of the asset manager and the o&m contractor overlap sometimes, and technical asset management can be assumed by either the O&M contractor or the asset manager.
III. Benefits of Solar Power Plant O&M Service
1. Save time: On the motto that prevention is better than cure, it helps businesses save time on troubleshooting.
2. Cost saving: regular maintenance inspection obviously less to happen will save a lot of costs for customers
In developed countries, it has been shown that a solar power plant with proper operation and maintenance (O&M) procedures will result in 10% to 20% higher operational efficiency.
3. High reliability: with a technical team with experience in operation and maintenance of many large solar power plants, with the coordination of experts from equipment manufacturers, and with effective support. of specialized machinery and equipment, customers will be assured when participating in the operation and maintenance (O&M) service of EPC SOLAR.
