Utility-Scale & Grid-Connected Solar Projects

Our Utility-Scale Solar Services

We deliver eight integrated workstreams that follow the full project lifecycle — from early development decisions through to operational optimization. Each workstream is independently scopeable, but most clients engage us across multiple stages to maintain technical and commercial continuity.

Development, Feasibility & Project Structuring

Early decisions shape the long-term economics of a solar project. We help clients screen sites, validate energy yield assumptions, define the grid connection strategy and structure projects so that downstream engineering, contracting and financing decisions are well-founded.

• Site screening and technical due diligence (irradiation, land, constraints)
• Energy yield assessment and production modelling (PVSyst-based, P50/P90)
• Grid connection strategy and application support — POC identification, capacity availability and utility engagement
• Load vs. export analysis and connection scenario optimization
• Preliminary system sizing (DC/AC ratio, clipping optimization)
• Permitting and regulatory roadmap
• Environmental and land-use constraints assessment
• CAPEX/OPEX benchmarking, financial modelling (LCOE, IRR, NPV) and early-stage risk assessment

Our feasibility deliverables are designed to be defensible at investment committee, lender due diligence and utility application stages — not just internal planning documents.

Grid Integration & Power System Engineering

Grid integration is where many utility-scale projects encounter their most significant technical and commercial risks. Our power system engineers conduct the studies needed to obtain utility approval, validate equipment ratings and confirm that the plant will operate reliably under all expected grid conditions.

• Load flow and network studies
• Short-circuit analysis and equipment rating validation
• Grid code compliance assessment for utility-specific requirements
• Harmonic analysis (IEEE 519 compliance)
• Reactive power and voltage control studies
• Dynamic and transient stability analysis
• Protection coordination studies
• Curtailment and export limitation assessment
• Interconnection studies for utility approval, with grid modelling in ETAP / DigSILENT

We work directly with utilities such as DEWA, SEC, ADDC, KAHRAMAA, OETC and others to align studies with their specific grid code and submission requirements.

Engineering & Design (Owner’s Engineer / Developer Support)

As Owner’s Engineer, we develop or independently review the engineering package on behalf of the project sponsor or developer — verifying that design choices serve long-term performance, maintainability and grid compliance, not just short-term EPC convenience.

• Plant architecture and system configuration
• DC system design (string sizing, inverter selection, losses optimization)
• MV collector system design (cables and/or overhead lines)
• Substation and grid interface design (33 kV / 132 kV / higher voltage levels)
• Utility interface engineering — bay allocation, protection philosophy alignment, SCADA integration
• Earthing and lightning protection systems (IEC / IEEE compliant)
• PPC / EMS control philosophy and grid compliance strategy
• SCADA and communication systems (IEC 61850 where required)
• Technical specifications, design basis preparation and independent design review / IFC validation

Tendering, Procurement & Contractual Structuring

A well-structured EPC contract is one of the most important risk-management tools in a utility-scale solar project. We help clients prepare technical and commercial tender documents, evaluate bids on a like-for-like basis, and structure contracts that allocate risk fairly between the developer, EPC contractor and lenders.

• Preparation of RFP and Employer’s Requirements (FIDIC-aligned)
• Technical specifications and BOQ development
• Bidder prequalification and tender management
• Technical and commercial bid evaluation
• EPC contract structuring and risk allocation strategy
• Definition of performance guarantees — PR, availability, capacity
• Alignment of testing, commissioning and acceptance criteria (PAC/FAC)
• Constructability review and EPC capability assessment
• Interface definition between plant, grid and utility

Financial, Legal & Bankability Advisory

Our financial and bankability advisory connects the engineering reality of a project with the assumptions in financial models, contracts and lender documentation. We work alongside the project’s commercial, legal and tax advisors to make sure technical risks are properly reflected in financial structures — and that financial assumptions hold up to engineering scrutiny.

Financial Modelling & Optimization

• Development of bankable financial models
• LCOE optimization and sensitivity analysis
• P50 / P90 energy yield integration into financial models
• CAPEX/OPEX validation and benchmarking

Revenue & Risk Structuring

• Revenue risk assessment (curtailment, grid outages, availability)
• Tariff and PPA structuring support
• Delivered energy definition and payment mechanism alignment
• Performance and availability guarantee alignment

Tax & Fiscal Structuring

• Assessment of local tax regimes (corporate tax, VAT, withholding tax)
• Project structuring considerations (SPV setup, ownership models)
• Depreciation and capital allowance optimization
• Assessment of incentives and exemptions, where applicable
• Impact of tax on project IRR and cash flow
• Coordination with financial and tax advisors

Contractual & Regulatory Alignment

• Technical review of EPC contracts and project agreements
• Grid connection agreement support with utilities such as Saudi Electricity Company and Dubai Electricity and Water Authority
• Regulatory alignment with authorities such as the Saudi Electricity Regulatory Authority

Bankability & Lender Interface

• Lender’s Technical Advisor (LTA) services
• Independent engineering and due diligence
• Bankability review of contracts and technical assumptions
• Risk matrix development for lenders and investors

Project Management & Construction Supervision

We provide on-site and remote support during construction to make sure the plant is built to specification, on schedule and to a quality standard that supports long-term performance and warranty enforcement.

• Owner’s Engineer services during execution
• Design review and approval management
• QA/QC implementation (ITPs, FAT, SAT)
• Site supervision (civil, electrical, installation)
• Interface management with utility and stakeholders
• Progress monitoring and reporting
• Variation and change order evaluation
• HSE compliance oversight

Testing, Commissioning & Grid Compliance

Commissioning is where contractual performance promises become measurable, and where utility approval to energize is granted or refused. Our team supports the full testing and commissioning sequence — from pre-energization checks through grid compliance certification and Final Acceptance.

• Pre-commissioning inspections and system verification
• Grid compliance testing including fault ride-through (FRT)
• Reactive power capability and voltage control verification
• PPC and plant controller response validation
• SCADA and communication system testing
• Performance ratio (PR) validation
• Grid code compliance certification
• Provisional and Final Acceptance (PAC/FAC) support

Asset Management & Operational Optimization

Once a project is operational, the focus shifts to maximizing energy yield, minimizing degradation losses and protecting long-term returns. We support asset owners with structured performance monitoring, KPI tracking and operational interventions that improve plant economics over the asset lifetime.

• Performance monitoring (IEC 61724 aligned)
• KPI tracking (availability, PR, system losses)
• O&M strategy optimization
• Fault analysis and root cause investigation
• Energy forecasting and performance analytics
• Repowering and plant upgrade strategies

• Independent, vendor-neutral advisory — we work for the project owner, not the equipment supplier or EPC.
• Deep capability in PVSyst yield modelling and ETAP / DigSILENT grid integration studies.
• Familiarity with utility submission processes across the GCC, MENA and broader regions.
• Experience as Owner’s Engineer, Lender’s Technical Advisor and Independent Engineer.
• FIDIC-aligned tendering and contractual experience for EPC and O&M structures.
• On-the-ground supervision capability, supported by remote engineering teams.
• Continuity from feasibility through long-term asset management — one team across the project lifecycle.
