Lower energy cost for wastewater treatment plants
Using an advanced process and energy simulator, Delprosa demonstrates how to cut electricity costs while maintaining effluent quality.
Opportunities to reduce energy cost
The energy transition is disrupting retail tariffs and creating new opportunities in wholesale electricity markets. With these dynamic prices, total energy costs depend more on how the plant responds to market signals than on plant loads and effluent quality alone.
Delprosa shows you how to cut energy costs without compromising plant stability or effluent quality. Plant managers get the numbers they need to decide whether to accept a tariff change, adjust plant operations, allocate capital, or expose the site to spot prices.
Price-responsive control at work

Will an alternate tariff be cheaper?
While new tariff structures can look appealing, they can drive up long-term costs if the plant cannot adapt. The simulation goes beyond a standard load profile, showing what price-responsive control can achieve.
Does solar or a battery pay for itself?
Whether solar, cogeneration or batteries pay depends on how well they fit plant operations, timed energy costs and grid rules. The simulation dispatches each asset against real loads and demand windows, then reports capital cost, saving and returns.
How to reduce energy costs and meet targets?
Aeration, pumping and sludge processing can often shift to cheaper periods while peak demand charges are held down. The simulation checks effluent quality and stability as well as the net saving, which is hard to forecast otherwise.
What is the best way to debottleneck the plant?
Hydraulic and biological bottlenecks shift with influent fluctuations, so they often go unnoticed until the simulator and results highlight the undersized components. The built-in static sizing guide flags likely constraints before a dynamic run.
How the savings are found
-
01
Set up the plant and tariff
Your plant is built from your own data, and your current and alternative electricity tariffs are loaded with it.
-
02
Run the simulation
A full year at five-minute resolution, with local weather driving the flows and temperatures.
-
03
Compare the cases
Standard against price-responsive control: cost line by line, quality against your limits, and net present value.
How we are engaged
What our fee covers
Delprosa provides a consulting service using the simulation model. We can take full responsibility for configuring the model, analysing the results, preparing the business case, managing the implementation of price-responsive control and monitoring it afterwards. Alternatively, you can self-manage any part of that under a licence, with an agreement that sets what functionality each person has, so the tool always fits the selected service.
Contract changes
A retail electricity contract is between your organisation and your retailer. Delprosa is not party to it, does not negotiate on your behalf and takes no commission from any retailer. We are paid a fee for the work, agreed before it starts, and that fee is our only income: the whole of the energy saving stays with you. With this approach, we stay independent of the offers on the table and have no vested interest in inflating any results.
