From plant assessment to live operation
Every engagement follows the same pathway and the model built in the first step is the model used at every step after it. Assess, simulate, build the business case. Where it stacks up, implement and run it live.
Five steps. One simulation model.

What differs between the three routes is only what the model is evaluated against: your current tariff, alternative offers, or wholesale spot. The business case, approval and delivery steps are shared.
Phase 1: Data gathering and model configuration
Done independently, using your plant data and real market/tariff data, before any capital or operational commitment. The same for every route.
- Assess plant operations, constraints and retail tariff. Real limits on pumps, blowers and storage/generation, so the model reflects what your plant can actually do. Your current tariff and contract position are recorded because the value of any change depends on what you are moving away from.
- Build and validate the model. A simulation engine configured to your plant, not a plug-and-play model from another plant, checked against your actual data before it is used for anything decision-grade. It starts from proven process fundamentals, not from scratch.
Phase 2: Analyse using the simulation model
With the model built and validated, the route determines what it’s evaluated against. Routes can be combined where circumstances support it.
Tariff Optimisation
Run against your current retail tariff, with sensitivity analysis, to find operational changes, including demand-charge management, that reduce cost within the contract you hold. No change to risk position.
Alternate Tariffs
Your historical load run through each proposed retail offer: demand charges, TOU rates and network charges. Compared on realistic operating outcomes rather than headline rates.
Demand Response
Run against wholesale spot price exposure, with sensitivity across price outcomes, to quantify what moving load onto the spot market is worth. It reflects real volatility, not a single scenario.
Whichever route applies, the outcome is the same: a transparent, plant-specific forecast of what will actually happen to cost and operation before you commit.
Phase 3: Business case and approval
Scenarios come together into a business case that quantifies the saving, its sensitivity and any case for further investment, for example whether additional storage or digestion capacity is justified once the energy value is accounted for. Built to go before your board as it stands. The decision is entirely yours; if the numbers don’t stack up, the question has still been answered and no further spend is made. How routes compare →
Phase 4: Control and contract
Tracks can run in parallel where a business case covers both.
Control scheme (Tariff Optimisation & Demand Response)
Delprosa can project-manage SCADA and control integration with your systems integrator through to commissioning. Or you can manage it internally using the business case and control logic as the brief. Either way, the logic built into SCADA reflects the constraints validated in simulation.
Contract change (Alternate Tariffs)
A contract change is between your organisation and your retailer directly. Delprosa is not party to it and does not negotiate on your behalf. We provide the quantified basis: assessing what the retailer puts forward, re-running the model on revised offers, and supporting your procurement/negotiation process.
Phase 5: The same logic that produced the analysis drives the plant
Tariff Optimisation / Demand Response: Forecast-driven price-responsive control as validated in simulation. Low wholesale prices tend to coincide with high renewable output, so the shift also lowers net emissions. Operators retain manual override.
Alternate Tariffs: Billed under the optimised structure. The cost model becomes the ongoing reference. Retail and network structures drift over time. The model keeps the arrangement under review so it does not quietly go stale.
A commissioned scheme needs ongoing stewardship
Market conditions, tariff structures and plant conditions change. An arrangement validated at commissioning can lose value quietly.
- Measurement & verification: periodic reporting against a defined baseline for a clear figure on savings delivered.
- Forecasting model recalibration: as NEM price behaviour shifts.
- Control scheme health checks: as reservoir capacity, inflow patterns or asset condition change.
- Tariff and market reviews: against current network/retail charges and upcoming regulatory changes.
- Annual business case refresh: revisiting the case with actual data and identifying scope expansion.
A consultancy fee, with no interest in the answer before the numbers are run
A fee, not a stake
Paid for work done: building the business case and quantifying the saving before any control scheme is built or contract changed. No revenue share, no retailer commission and no ongoing cut of savings. Nothing about the recommendation changes if the numbers change.
What sits behind the numbers
Shifting operating parameters affects stability, effluent quality and downstream processes. The case is quantified from a validated model of those effects, built from the plant outward, not backwards from a target saving.
The first step is a plant assessment
Every plant is different. The assessment, covering your pumps, blowers, digestion/generation assets and the tariff or offers on the table, tells you quickly whether there is a case worth building and which route fits.
