Key Responsibilities 1. Cost Estimation & Budgeting • Prepare and review CAPEX estimates for renewable energy projects, including solar PV, wind, battery energy storage systems (BESS), hybrid systems, grid interconnection, EPC packages, equipment supply, land, development, insurance, and contingency. • Develop cost baselines and budgets using feasibility studies, engineering inputs, supplier quotations, and market benchmarks. • Prepare and maintain OPEX estimates covering operations and maintenance, asset management, insurance, land leases, grid charges, battery replacement, and decommissioning. • Develop work breakdown structures (WBS) and cost breakdown structures (CBS), validate quantities and unit rates, and review bills of quantities (BOQs). • Evaluate EPC, OEM, and supplier bids through scope comparison, bid normalization, whole-life cost analysis, and sensitivity assessments. • Maintain cost databases, benchmarking records, documented estimating assumptions, and lessons learned. 2. Project Cost Control & Reporting • Monitor project expenditure and commitments against approved budgets and cost baselines. • Analyse cost variances, identify emerging risks, monitor contingency usage, and recommend corrective actions. • Prepare monthly cost forecasts, cash flow projections, cost-to-complete estimates, and estimate-at-completion reports. • Review contractor and supplier invoices against contractual terms, verified progress, and milestone achievements. • Assess variations, change orders, claims, milestone payments, and final accounts under EPC and supply contracts. • Coordinate site progress and quantity verification with construction teams and owner s engineers before payment recommendations. • Prepare cost reports, dashboards, budget-to-actual reconciliations, and management updates. • Support lender drawdowns, independent engineer reviews, investor reporting, and project cost due diligence. 3. Financial, Commercial & Project Coordination • Coordinate with engineering, procurement, finance, legal, and project management teams to align cost estimates with project scope and contractual obligations. • Maintain CAPEX and OPEX inputs to financial models and investment cases, ensuring consistency with approved budgets and current estimates. • Establish contingency and risk allowance methodologies and incorporate identified risks into cost forecasts. • Apply earned value management and integrate cost reporting with project schedules using Primavera P6 or MS Project. • Maintain accurate cost records in ERP and cost management systems, ensuring monthly reconciliation with finance records. • Develop advanced Excel models and reporting dashboards, including Power BI where applicable. • Consider applicable tax, customs, local procurement, and in-country value requirements across Oman, the GCC, and other project jurisdictions.
