Reduce your plant’s energy costs without jeopardising stable operations
Delprosa builds a validated simulation of your treatment plant, applying our decades of wastewater process design and operations experience, and runs it against the real wholesale market and your retail tariff. The simulation incorporates an advanced control algorithm of the operating plant, so energy cost savings are quantified under that control and compared with your current operating strategy, to build a business case for implementation. It also includes a visualiser of the process, so you can see how the plant would be controlled.
What the assessment delivers before implementation
- ✓ A simulation built on wastewater process knowledge, validated against your own data
- ✓ A transparent forecast of the cost, and of the operation
- ✓ Savings quantified, with sensitivity to price volatility
- ✓ The treatment process is protected, and operators stay in control
Three routes to lower energy costs, quantified by one simulation
Energy is one of the largest controllable costs at a treatment plant. Every route starts the same way: an assessment of your plant, then a validated simulation of it.
Demand Response
The business case for moving some or all of your load onto the wholesale spot market, and the design of the pump scheduling that captures the opportunity without compromising treatment.
Tariff Optimisation
The operational changes available within your existing retail contract: savings captured without changing your risk position.
Alternate Tariffs
A model of how your plant would perform under alternative tariff structures, so competing offers are compared on realistic operating outcomes rather than headline rates.
Historic usage records how the plant was controlled. The simulation shows how much can be saved using advanced price responsive control.
Your energy cost is set by the pattern of electricity use across the plant, and that pattern is set by how the plant is controlled. A high-level average, or a look at historic usage, only tells part of the story: it shows how the plant ran under the control strategy it had at the time, not what it could achieve under a control strategy designed to minimise energy cost. By overlaying that advanced control scheme inside a validated simulation of the plant, Delprosa shows the full story of what is possible, and quantifies the savings with far more certainty than generic analysis.
Modelled as an operating plant, not a simplified load
Generic simulation platforms treat the plant as a simplified load rather than a full operating system, so a change that looks good on one part of the process can quietly create a problem somewhere else.
Grounded in how treatment plants actually work
The simulations use the same process engineering fundamentals used to design and operate treatment plants, underpinned by research into integrated energy and wastewater systems.
A transparent, plant-specific forecast
The recommendation comes with a forecast of what will actually happen across the operation as a whole, not just to the energy cost, so you see the trade-offs before you commit to a change.
Assessing a capital investment
Any of the three routes can be extended into a CAPEX Business Case Assessment: testing whether new or larger assets such as pumps, blowers, storage, solar PV, batteries or cogeneration would strengthen the outcome. Where a case supports moving ahead, Delprosa can help deliver the engineering design and project management through to commissioning.
Industrial experience, applied to wastewater treatment
Dr Rickey Donald has worked across energy-intensive industries for decades, including steel, minerals, chemicals, pharmaceuticals, food and packaging manufacturing, oil and gas, and water treatment, and more recently in clean tech and energy monitoring. For clients, that breadth is a practical advantage: the simulation reflects how real industrial processes respond to changes in operation, so recommendations hold up in practice, not just on paper. It shapes every assumption inside the model, such as how pumps and blowers behave under partial load, how much flexibility digestion and process storage genuinely offer, and where the limits of safe operation sit, rather than treating the plant as a simplified load.
A wastewater focus, by design
Most of Delprosa’s expertise, and the current version of the simulation, is written specifically for wastewater treatment plants. That is where the operational detail is deepest and the model is at its most accurate.
The same method applies elsewhere
The approach extends to any plant with flexible, controllable load: pumping, compression, refrigeration, batch processing. If you operate outside water and wastewater, it is worth a conversation rather than assuming this is water-specific.
The model is built on how treatment plants actually work
The strength of the Delprosa approach is not the software. It is decades of design and operations knowledge of wastewater treatment processes, and the simulation model is built on exactly that knowledge. It starts from the plant, not the market.
Built for wastewater treatment
Pumping, blower control, digestion and generation are modelled as the operating system they are.
The plant sets the limits
What can safely be deferred is set by treatment performance and operating constraints, before any savings figure is discussed.
Process understanding, not a target percentage
The business case is built from the plant outward, never backwards from a target savings figure.
You stay in control of the engagement
Retail negotiation: led by you
You hold the commercial relationship, and Delprosa stays independent, so negotiating with your retailer is something you lead. Delprosa supports those discussions where useful, without ever becoming the intermediary.
Control system integration: your choice
Implementation is approached however you prefer. Many clients mandate their trusted integrator, and Delprosa works with any integrator you choose. You can project-manage the implementation yourself, or hand it to Delprosa as part of a delivery engagement.
The first step is a plant assessment
It tells you quickly whether there is a case worth building, and which of the three routes fits your circumstances. It is the same first step under every engagement.
