Technical foundations for the REdispatch suite. Currently viewing RDX-DF: the foundational energy and financial engine.
1. Operational Dispatch Logic
REdispatch utilizes a deterministic, rule-based dispatch model. This ensures that results are consistent, auditable, and free from the non-transparency often found in optimization-based solvers.
Standard Energy Priority
During operational hours, energy is moved according to a strict hierarchy:
- Direct Use: Renewable generation satisfies load immediately.
- Storage: Surplus energy is directed to charge the BESS.
- Monetization: Remaining surplus is exported to the grid.
- Curtailment: Excess power is clipped if all other sinks are full.
2. Battery Storage (BESS)
The storage model accounts for round-trip efficiencies and degradation-based capacity derating. Charging is restricted to renewable surplus only (no grid-to-battery charging) to ensure high additionality and renewable integrity.
3. CAPEX & Scaling
Financial outputs are computed after the dispatch cycle is complete. CAPEX is modeled through two primary methodologies to reflect real-world market conditions:
Linear Mode
Simple unit-cost scaling for standard asset sizing.
Scale-Index Mode
Power-law scaling to model economies of scale for large-scale deployments.
4. OPEX & Operational Revenue
The model computes annual operating expenses including fixed O&M, transmission charges, and energy tariffs. Revenues from grid exports are treated as "negative OPEX," reducing the net operational burden of the project.
5. Discounting & LCOE
REdispatch provides a full lifecycle financial view using end-of-year cash flow timing. The Levelized Cost of Energy (LCOE) is the primary KPI, computed by dividing the total discounted project costs by the total discounted served energy.
| Financial Metric | Accounting Basis |
|---|---|
| NPV | Discounted sparse cashflow schedule |
| LCOE | Net lifecycle cost / Total energy served |
| CRF | Standardized capital recovery factor |
