Detailed information about RES and GES Project Management and Consulting

RES and GES project management — this guide covers the scope, application method, quality criteria and reporting process for your needs.

Technical roadmap for RES and GES investments

RES and GES project management is not merely about preparing a work schedule. The production target of a wind or solar power plant must be considered together with connection capacity, site conditions, the permitting calendar, equipment supply, and the financing plan. A wrong connection, layout, or technical specification decision made in the early days of the project can create cost increases and schedule losses in later stages. Plan-Test applies an integrated renewable energy consulting approach that ensures technical decisions support one another from the investment idea through provisional acceptance and commercial operation.

At the start of the work, existing documents, land data, connection opinions, production estimates, and the investor's objectives are reviewed. Critical decision points and institutional approvals are entered into the master schedule; alternative scenarios are created for activities that carry delay risk. In wind power plant consulting and solar power plant consulting services, the goal is to gather technical information from different contractors under a common project language and give the investor measurable progress visibility.

Feasibility, site, and grid connection assessment

In a power plant feasibility study, installed capacity is not a sufficient success criterion on its own. Site accessibility, ground and topographical conditions, transmission line distance, the substation solution, internal auxiliary needs, losses, and grid constraints are analyzed together. In RES projects, turbine layout and the electrical collector system directly affect one another; in GES projects, the panel-inverter architecture and the choice of cables, transformers, and switchgear directly affect one another. For this reason, coordination of the electrical, civil, and mechanical disciplines at an early stage strengthens the investment's viability.

In the connection assessment, short-circuit power, load flow, voltage variation, reactive power requirement, the protection approach, and the operating requirements of the connection point are reviewed. TEİAŞ, TEDAŞ, and the relevant distribution company criteria are evaluated according to the project type. Assumptions, data sources, and uncertainties are stated clearly in the feasibility report. In this way, the investor sees not only a favorable result but also under which technical conditions the result is valid and which data must be verified in the next stage.

Management of the design, tender, and procurement process

Implementation success begins with a correctly prepared technical specification and clear interface definitions. Within the scope of E-BoP consulting, Plan-Test establishes the technical requirements for the substation, collector system, transmission line, protection and control, SCADA, auxiliary systems, and field tests. Single-line diagrams, layouts, cable lists, calculation reports, and equipment data sheets are reviewed for consistency with one another. Design comments are prepared not only on the basis of regulatory compliance but also taking maintainability, operational safety, and future capacity changes into account.

During the tender process, scope boundaries, exclusions, performance criteria, and acceptance tests are clarified so that offers can be compared on the same technical basis. The review of supplier documents, monitoring of the production and shipment schedule, planning of factory acceptance tests, and site delivery checks are tied into the project management plan. This approach helps prevent a low initial price from turning into high change costs later and helps ensure that the system the investor purchases meets the targeted technical performance.

Site implementation, quality control, and progress tracking

When different contractors work on site at the same time, the risk of interface errors increases. In site supervision, Plan-Test uses the approved projects, method statements, control and test plans, and the current work schedule as its reference. Cable routes, grounding connections, equipment installations, labeling, torque checks, and secondary circuits are monitored in stages. Nonconformities are recorded with a photograph, location, the relevant drawing, and the proposed correction; an item is not considered complete until the closure evidence is seen.

Progress reports show not only the percentage of work completed but also the technical obstacles affecting completion and upcoming decisions. Supply, approval, and test activities on the critical path are updated regularly. In technical meetings among the employer, the main contractor, and the equipment suppliers, decisions are recorded with an owner and a target date. In this way, RES and GES project management becomes an effective control mechanism that links daily on-site developments to the investment's budget, quality, and acceptance objectives.

RES and GES test, commissioning, and provisional acceptance management

In the RES and GES commissioning process, primary equipment, protection relays, metering systems, communication, SCADA, the plant controller, and grid connection functions are combined into a single test plan. It is essential not to proceed to the energization step before pre-commissioning checks are complete, to prioritize deficiencies on a risk basis, and to keep test records traceable. Plan-Test reviews the contractor's test sheets, witnesses the required field tests, and compares the results against the project criteria.

Within the scope of provisional acceptance consulting, approved projects, as-built drawings, test reports, certificates, operating instructions, and punch lists are checked for completeness. Before the acceptance committee convenes, site readiness is assessed and the closure of open items is coordinated. The energization sequence, responsibilities, and communication channels are clarified with a written plan. After acceptance, regular maintenance of records required for performance tracking, warranty items, and final acceptance is recommended.

The contribution of independent technical consulting to the investor

The independent technical consultant does not take the place of the designer or the contractor; it ensures that the investment objectives are preserved across all technical parties. It makes the rationale, risk, and schedule impact of decisions visible. Especially in multidisciplinary renewable energy projects, a seemingly minor interface gap can come back as production loss, rework, or acceptance delay. Regular technical review and field verification help catch these risks at an early stage.

Plan-Test's RES and GES consulting approach aims to ground the investor's decisions in verifiable data. Deliverables include the executive summary, an open items list, a risk matrix, the technical assessment, and recommended actions together. In this way, the project team can track which issue is important and why, who is responsible, and when it must be concluded. The result is an energy investment that is managed with the same quality objective from planning to testing, is ready for operation, and has complete documentation.

Plan-Test’s quality, safety and reporting approach

Plan-Test does not treat the service scope merely as a list of operations to be performed on site. The facility's operating objective, outage availability, existing documentation, equipment history, and risk level are evaluated together. Before the work begins, responsibilities, access conditions, de-energization and re-energization steps, and reporting expectations are clarified. This is intended to keep teams working from the same plan, prevent critical checks from being skipped, and make efficient use of site time. Because each project is planned according to its own technical conditions, the method, devices, team size, and delivery documents to be used are clearly defined at the proposal stage.

Our quality approach is based on explaining what the result means rather than presenting the measurement result on its own. The calibration status of the test devices used, the ambient and load conditions, the connection arrangement, the applied standard, manufacturer criteria, and any previous measurements are linked together in the report. Nonconformities are classified by severity; findings requiring immediate intervention, issues that can be addressed in planned maintenance, and trends that should be monitored are separated from one another. This method helps the investor, the operations manager, and the site team turn the same technical data into a decision-ready output.

Occupational health and safety is an inseparable part of all services. The site-specific risk assessment, personal protective equipment, lockout-tagout steps, absence-of-voltage verification, and grounding and bonding rules are reviewed before the field work begins. Inspections carried out in an energized facility are based on safe approach distances and operating instructions. Plan-Test's goal is to combine technical verification with a safe working discipline in the same process and deliver sustainable, traceable, and auditable engineering services in 1–380 kV energy facilities.

At the proposal and mobilization stage, clearly defining the scope matters for both the employer and the site team. Plan-Test determines the required activities by reviewing the existing drawings, the equipment list, the facility's operating regime, previous reports, and the employer's expectations. Out-of-scope items, necessary preparatory work, the need for de-energization, operational accompaniment, and third-party responsibilities are put in writing. When a new condition arises on site, no uncontrolled scope change is made before its impact is evaluated in terms of technical, schedule, and resource aspects. In this way, all parties understand throughout the project which activity is being performed and why, which data is expected, and against which criterion acceptance will be made. This clarity reduces repeat visits and misplaced expectations while making the delivered engineering service comparable.

The quality of field work depends on the team's experience and cross-disciplinary communication as much as on the equipment used. Plan-Test assigns tasks according to the test or maintenance steps and opens points requiring primary, secondary, project, and operational knowledge to joint evaluation. Measurement devices are used with accessories suited to the application, their calibration validity is checked, and raw data is stored securely. When a critical result is observed, the connection, device settings, environmental conditions, and the equipment's operating history are reviewed again instead of jumping to a hasty interpretation. Verification with a different method is proposed when necessary. This culture of technical scrutiny helps prevent incidental or erroneous measurements from steering the decision process and helps define the real risk on site more accurately.

Completion of the service does not end with the delivery of the report; the actions in the report must be implementable and traceable. Plan-Test links its recommendations to priority, the responsible discipline, the recommended due date, and the verification method. If the employer wishes, a scope for a technical meeting, post-correction check, or repeat measurement can be established for critical items. When new results are compared with historical data under the same equipment code, the facility's condition trend becomes visible. These records support the preparation of the future maintenance budget, spare parts plan, modernization decisions, and outage calendar. The goal is not to document a single project moment, but to build a corporate technical memory that contributes to safe operation and high availability targets throughout the energy facility's entire life cycle.

In every engagement, the relevant national legislation, the grid operator's requirements, IEC and IEEE standards, and the equipment manufacturer's instructions are considered together. While the general provisions of the standards are adapted to the facility's actual conditions, the contract and approved project requirements are also preserved. Where several criteria give different limits, the acceptance approach used is explained in the report; uncertain points are recorded with the employer as a technical decision. Using unique site codes instead of equipment names in documents strengthens traceability among drawings, test results, photographs, and actions. With this documentation discipline, Plan-Test aims to ensure that the technical evidence needed during an audit, provisional acceptance, warranty discussion, or a future failure investigation can be found quickly and reliably.

For the site program you need, it is sufficient to share the facility type, voltage level, equipment count, location, and target date. After the preliminary review, the technical team clarifies the appropriate scope, preparations, and delivery plan.
