Common use of Operational Reports Clause in Contracts

Operational Reports. The Operational Reports will provide an overview of the Project’s performance across the first 12 months of operations (Interim Operational Report) and the second 12 months of operation (Final Operational Report). The reports should describe how the Project is being used (i.e. applications), its technical performance, and its ability to capture revenue in different applications. The expected length of this document is at least 15 pages of substantive content. The Operational Reports should include: (a) Executive summary (b) Project overview and objectives (c) Description of project operation and performance, including: (i) Project status (cost and schedule update) (ii) Safety and risk management (iii) Environmental impact (iv) Stakeholder and community engagement and feedback (v) Operation and maintenance requirements and cost (vi) Impact of soiling on heliostats and associated cost (vii) Performance (viii) Discussion on technical performance metrics (clearly defined with units and location of measurement, where applicable), including: (A) round-trip efficiency (including commentary on site conditions such as incident solar irradiation, wind speed, temperature and humidity), comparison of forecast and actual round trip efficiencies Advancing Renewables Program Funding Agreement | Vast Solar, Port Augusta Concentrated Solar Power Project 2022/ARP026 68 (B) ramp rates (C) operational constraints (D) degradation (including commentary on site conditions such as temperature and humidity) (E) auxiliary power usage (F) equipment availability (including commentary on individual equipment performance) (ix) Description of performance during any islanding events. (x) Safety and environmental performance. (xi) Applications and usage including: (A) Analysis of CSP charging/discharging behaviour and storage duration, including participation in different applications (e.g. energy arbitrage / time shifting, contingency FCAS, regulation FCAS etc). (B) New revenue opportunities (if any) (C) Revised LCOE models using operational data (d) Key challenges lessons learnt
