Renewable Round-the-Clock (RE-RTC) Power Cost – Demonstration Model
This interactive model is provided for illustrative purposes only.
Many global energy and climate expert agencies increasingly emphasise “electrify everything” as a central pillar of long-term decarbonisation pathways.
In its strictest interpretation, round-the-clock power implies continuous availability for all 8,760 hours of a non-leap year.
This demonstration model evaluates RE-RTC costs using optimisation-based techniques, with solar photovoltaic, onshore wind, and battery storage capacities determined endogenously by the model.
Scope and use of the demonstration model
RE-RTC system design is highly end-use specific and strongly dependent on location-specific solar and wind generation profiles. A comprehensive assessment therefore requires consideration of a wide range of technical, operational, and commercial factors, which is beyond the scope of this demonstration model
Accordingly, this demo is intended primarily to explore cost sensitivities around key high-level parameters, including unit solar and wind power costs, battery installed cost, minimum hourly guaranteed power requirement, and the capital recovery factor. The analysis is carried out for a reference RE-RTC requirement of 1 GW (1,000 MW). To maintain transparency and conservatism, the model assigns zero revenue to excess solar and wind generation
Karandikars & Associates’ commercial RE-RTC assessment framework incorporates substantially greater detail, including hourly realisable revenues for excess generation based on proprietary analysis of power exchange prices, location-specific renewable profiles, and additional technical and commercial constraints relevant to project-level decision-making
