correctivemaintenance

actions and/or techniques (immediate or deferred) taken to correct failures,

breakdowns, malfunctions, anomalies or damages detected during inspections, or

through monitoring, alarming, or reporting or any other source. the actions are

desired to restore the PV system back into regular and required operation mode.

Data & monitoringrequirements

hardware and software, technical and functional specifications to collect, transmit

and store production, performance and environmental data for plant management.

Documentation management system

a management system that records, manages and stores documents required for

O&M, such as technical plant and equipment documentation and drawings,

maintenance manuals, photos and reports, including the various versions that are

being created by different users,reviews and approvals.Documentation management

system also defines a proper format and use (information exchange).

environment,

Health & Safety (eH&S)

Environment, health and Safety indicates the activities performed to ensure

environmental protection, occupational health and safety at work and on site,

applicable to staffandvisitorsaccordingtothenationalapplicable lawsandregulations.

extraordinaryMaintenance

actions and/orworks performed in case of major unpredictable faults, such as serial

defects, force majeure events etc, that are generally considered outside of theordinary course of business.

Grid code compliance requirements

Equipment,procedures,actionsandactivities requiredby the respectivegridoperator(s)

in order to complywith grid safety, power quality and operating specifications.

Insurance claims Customer’s activities required to claim a reimbursement based on specific insurance policy terms

Key Performance Indicator (KPI)

a technical parameter that helps the stakeholders to evaluate the successful

operation of a PV plant and/or the success of the O&M Contractor’s activities.

Management of change

Management of change defines the way to handle necessary adjustments of the design of a PV power plant after the Commercial Operation Date. Changes requirea close cooperation between the plant owner and the O&M Contractor.

Performance analysis & improvement

Measurements, calculations, trending, comparisons, inspections etc performed in

order to evaluate the PV plant, segments and/or single component performance,

site conditions, equipment behaviour etc, and to provide reports and assessment

studies to interested parties (customer, public authority, etc).

Personnel & training

Operators, technicians, engineers and managers employed for the execution of the

O&M activities and training plans/programmes to train them on relevant PV plantrelated aspects and to keep them continuously updated on their respective roles.

Power plantcontrols

actions required by the grid operator, for controlling active and/or reactive power

being fed into the grid, other power quality factors that are subject to adjustments

and/or (emergency) shut down (if applicable).

Power plant monitoring

Overall monitoring of the functioning, energy generation and reference data of the

PV plant and its components, which is performed through real-time (web based)

monitoring software. the monitoring operates 24h/365d and is fed by in-plant data-

logging systems that collect data from different plants as well as by irradiation and

temperature measurements from particular sensors and other sources such as

meteorological information (data acquisition 24h/365d).

Power plant

supervision

the activity to supervise and analyse data provided by the monitoring system which

is performed by experienced human resources during daylight hours and managed

by one or more control rooms (365 days/year). the reception and qualification of

the alarms from the monitoring tool is also considered to be part of the supervision.

Predictive

Maintenance

actions and/or techniques that are performed to help assess the condition of a PV

system and its components, predict/forecast and recommend when maintenance

actions should be performed. the prediction is derived from the analysis and

evaluation of significant parameters of the component (e.g. parameters related to

degradation). Monitoring systems and expert knowledge are used to identify the

appropriate actions based on a cost benefit analysis.

Preventive

Maintenance

actions and/or testing and/or measurements to ensure optimal operating

conditions of equipment and of the entire PV plant and to prevent defects and

failures. those take place periodically and according to a specific maintenance-

plan and maintenance schedules.

Power Generation Forecasting

adoption of forecasting tools calculating expected power production for a certain

timeframe from weather forecasts in order to supply the expected power

production to owner, grid operator, energy traders or others. this is normally

country and plant dependent.

Regulatory compliance

Compliance to any law, statute, directive, bylaw, regulation, rule, order, delegated

legislation or subordinate legislation directly applicable in the country where the

service is provided, as well as to any mandatory guidelines and measures issued

by a utility and any other competent public authority.

Reporting & other deliverables

Deliverables produced periodically, according to requirements detailed in the O&M

agreement or following best market practices, including PV plant performance, Key

Performance indicators, maintenance activities and work orders performed, alarm

handling, equipment status, warranty handling activities and spare parts tracking and

any other analysis performed in compliancewith theO&Mcontract requirements.

Security actions, procedures, equipment and/or techniques that are adopted on site and

remotely in order to protect the plant from theft, vandalism, fire and unauthorised

entry. Security services are to be provided be specialised security service providers.

Spare Parts

Management

activities that ensure availability of the right amount and type of components,

equipment, parts etc, either on site or in warehouses or in manufacturers’

consignment stocks, for prompt replacement in case of failure and/or to meet

guarantees under O&M contracts.

Warranty management Warranty management usually aggregates activities of a diverse nature which are linked to areas such as supply of equipment and services, and project construction. all these responsibilities (warranties) are usually materialised with the issue of the

Provisional acceptance Certificate (PaC) by the EPC. Warranty Management is the

activity that manages thesewarrantieswith the objective of reducing the costs and

response times afterwarranty claims for repair or replacement of certain PV system

components (under thewarranty of the EPC and/or the components manufacturer).
