Advanced Utility & Power Quality 10
- Captive Solar Against a Three-Shift Load Premium Values a rooftop or ground-mount proposal against the hour-by-hour load it is actually supposed to displace, rather than against annual consumption. Separates the units the mill consumes itself from the units it exports at a fraction of the tariff, reports what the maximum demand charge does as opposed to the energy bill, and sweeps plant size for the band inside which net present value hardly changes. What the Proposal Overstates the Saving By cost/yr
- Mill Power & Utility Load Schedule Premium Turns a department load list into maximum demand, transformer and generator ratings, capacitor requirement and contract demand, prices the energy and demand bill, and returns the specific energy in kWh per kilogram that a feasibility report should be using instead of a benchmark. Transformer Rating kVA
- Time-of-Day Load Shifting & Demand Charge Sheet Premium Tests a proposed load shift against the whole electricity bill rather than the tariff sheet. Prices the units saved by moving a load into a cheaper window beside the maximum demand created by concentrating loads there, reports which window carries the site peak before and after, and names the loads that cannot fit the window they have been assigned to. Net Effect of the Shift cost/mo
- What Power Interruptions Cost, and Which Departments to Back Up Premium Splits the cost of an interruption into the part that scales with its length and the part that does not, department by department, and compares the answer against what an outage log measured in hours implies. Sizes the backup worth installing rather than the backup that covers everything, and prices the same lost hours delivered as fewer and longer events. What Backing Up the Right Departments Saves cost/yr
- Dyehouse Heat Exchanger Fouling & Thermal Loss Predictor Quantifies scaling losses in heat recovery: fouled overall heat transfer coefficient, log mean temperature difference, clean and fouled duty, the share of capacity lost, and the annual energy and cost the fouling gives away. Fouled Heat Transfer Coefficient W/m²K
- Factory Skylight & Lux Distribution vs Inspection Quality Correlates inspection lighting with defect detection: daylight contribution through skylights, total daytime illuminance, detection rate by day and by night, the shift-to-shift detection gap and the extra defects escaping per thousand metres at night. Daylight Contribution lux
- Loom Motor Power Factor Correction Capacitor Calculator Sizes power factor correction for inductive textile loads: capacitor kvar needed to reach a target, apparent power before and after, the kVA and current released, and the utility penalty avoided monthly and annually. Capacitor Bank Required kvar
- Power Factor Correction kVAr Sizing, Demand Saving & Payback Sizes a capacitor bank from the tangent difference between present and target power factor, reports the apparent power removed from the supply, the distribution loss reduction that follows, and the demand charge and penalty the correction stops paying. Capacitor Bank Required kVAr
- Spinning Mill Inverter Harmonic Distortion Power Penalty Costs harmonic distortion from variable frequency drives: true power factor after distortion, additional network losses in kilowatts and kilowatt-hours, the cost of those losses, tariff penalty points above the utility threshold and total annual exposure. Annual Cost of Distortion /yr
- Textile Compressed Air Pipe Network Pressure Drop Modeler Calculates compressed air losses in distribution pipework: air velocity, pressure drop over pipe and fittings, pressure actually reaching the machines, the compressor energy penalty it causes, its annual cost and the pipe diameter a target drop would need. Pressure Drop bar

- Marginal Abatement Cost Curve: Which Decarbonisation Projects, and in What Order Premium Builds the abatement curve for a mill sequentially rather than by addition, so each project is priced against the plant the projects ahead of it leave behind. Reports what the list claims against what the plan delivers, how far the reduction that pays for itself actually goes, what the rest costs a year, the capital needed to reach a stated target, and the carbon price at which the whole plan is free. Abatement Counted Twice tCO2e/yr
- Restricted Substance Limit Register Premium Takes your own restricted substance limits and your own test results and does the three pieces of arithmetic that decide whether a lot actually clears: converts a chemical-basis result to what lands on the article, places the expanded measurement uncertainty against the limit rather than the bare number, and sums the families that share a single limit. Reports the lot twice, as read and as it would be read at the buyer laboratory, and prices the retest against the lot. Lot Fails as Read 0/1
- The Audit Fee, and the Cost of Being Audited Premium Costs a whole audit programme rather than its invoices: preparation weeks, the managers tied up on site, production stopped for the walkthrough, corrective actions and the re-audits, against the fees that are the only part anybody budgets. Then prices the part that is a second look at something already audited - the figure a supplier takes to a customer when asking for mutual recognition. Spent Auditing What Was Already Audited cost/yr
- What a Certified Programme Costs, and Why the Delivery Schedule Is the Price Premium Separates the standing cost of a certification - audits, licences, records, transaction certificates - from the segregation cost of running certified goods through a plant that also runs conventional ones. Reports the premium the programme genuinely needs, the certified volume below which no premium can carry it, which stage of the chain is dear and why, and what relaxing the delivery schedule is worth against what arguing about price is worth. What Relaxing the Delivery Schedule Is Worth cost/yr
- Boiler Steam Efficiency & Fuel Ratio Calculator Calculates direct-method boiler efficiency from steam output, steam and feedwater enthalpy and fuel input, with the steam-to-fuel ratio, heat balance, losses and the fuel cost of every tonne of steam generated. Boiler Efficiency %
- Caustic Soda Recovery Plant Efficiency & Payback Modeler Models a caustic recovery plant on a mercerising or denim line: caustic recovered per hour, the strong lye it makes, water the evaporator must remove, steam demand and the net hourly saving after steam cost. Net Saving /h
- Compressed Air Leak Cost Calculator Converts a measured compressed air leakage rate into wasted compressor power, annual energy and cost, the emissions behind it and the cost of every single CFM leaking — the number that justifies a leak survey. Annual Cost of Leakage /yr
- DPP Annex III Readiness Check Scores how many of the twelve elements in Annex III of the Ecodesign for Sustainable Products Regulation you can already produce a document for. Annex III is the menu a future delegated act draws a product passport from; no textile act exists yet, so this reports what you hold, not whether you comply. Annex III Elements Documented % of 12
- Dyehouse RO Recovery & Brine Reject Modeler (ZLD) Runs a salt and flow balance across a dyehouse reverse osmosis stage: permeate and brine flows, the salinity of each, the concentration factor the membranes see, evaporator duty for zero liquid discharge and the net utility cost against fresh water saved. Brine Reject Flow m³/h
- Effluent Colour ADMI Removal, Compliance Margin & Chemical Cost Converts inlet and outlet ADMI colour readings into removal efficiency and the margin against a discharge limit, sizes the coagulant and decolourising agent needed, and reports the chemical cost per cubic metre and the removal each unit of dose buys. Colour Removal %
- ETP Sludge from Solids, Coagulant and Biomass Adds the three sludge streams a textile effluent plant generates - removed suspended solids, coagulant floc and biological yield on removed COD - converts dry solids to wet cake at the achieved dryness, and prices disposal per day and per tonne of fabric. Wet Cake Generated t/day
- Failed Steam Trap Loss, Annual Cost & Survey Payback Applies Napier choked-orifice flow to a failed-open steam trap to give the steam it passes, scales it across the failed population, and converts the loss into annual steam tonnage, cost, boiler fuel, carbon and the payback on a trap survey. Steam Lost per Failed Trap kg/h
- Hydroextraction: G-Force, Residual Moisture & Drying Load Turns basket diameter and spin speed into g-force, converts a residual moisture figure into the water and the energy the dryer inherits, and sets the extractor's own electricity against the drying energy it avoids. Return on Extraction x
- Microfibre Release over a Garment Life Models microfibre shedding as a declining series across launderings, summing lifetime release, splitting it between what filtration captures and what reaches the environment, and scaling both to an annual production volume. Lifetime Release per Garment mg
- Stenter Exhaust Heat Recovery Payback Calculator Sizes a stenter exhaust heat recovery installation: heat available in the exhaust, duty actually recovered at the exchanger efficiency, annual fuel saved after boiler losses, the money that represents, simple payback and avoided CO₂. Simple Payback years
- Total CO₂e Footprint Calculator (Scope 1, 2 & 3) Builds a mill's total equivalent carbon footprint by adding Scope 3 value-chain emissions — purchased fibre, chemicals, freight and waste — to its Scope 1 and 2 totals, with emission intensity per kilogram and the share Scope 3 actually carries. Total Footprint t CO₂e/yr
