Plastics industry: medical plastics
Medical plastics manufacturers: reduce your cleanroom costs
At night, when injection molding machines stop, the cleanroom continues to filter, cool, heat, and humidify its air to maintain its classification. In medical plastics, this base load of electricity and gas is a year-round expense. Sirenergies helps you stabilize its price and recalibrates your subscribed power to match this base load.
Key industry figures
Managing the energy impact of air control in medical device workshops
A workshop producing under controlled environments pays for cleanroom energy day and night. This constant base load, which is relatively insensitive to production volumes, is well-suited to a multi-year purchasing strategy.

The energy profile of a medical plastics site
A cleanroom that consumes energy, whether the presses are running or not
The reality: controlled air that consumes energy day and night
Syringes, bags, catheters, sterile packaging: presses often operate in a cleanroom where the air is filtered, cooled, heated, and humidified continuously, even when the workshop is empty. Electricity powers the presses, fans, and chillers; gas, where available on-site, heats fresh air or produces steam for humidification. The sector, 93% of which is made up of SMEs (Snitem, 2026), often purchases this energy like a standard workshop, without isolating its base load.
Our role: secure costs without compromising qualification
Your quality managers and engineering departments retain control over the cleanroom. Sirenergies advises management before and after their decisions:
- A two-part purchasing strategy: the cleanroom base load at a fixed price, with the press consumption handled separately.
- Optimized delivery: TURPE (public electricity network usage tariff) power and options, and ATRD (third-party access to gas distribution networks) capacity for boilers.
- Data-driven monitoring: the impact of reduced ventilation outside of production hours measured at D+1 in Pilott, then reflected in the contract.
Your energy challenges
The 3 energy challenges for medical plastics manufacturing sites
Paying for controlled air that never stops, protecting production that cannot tolerate any downtime, and knowing the true cost of the controlled environment for each product: these are three questions every medical plastics site manager faces sooner or later. Here is Sirenergies' answer, regarding both contracts and data.
Absolute service continuity
A power outage or a drop in power quality can compromise a cleanroom's cleanliness rating and, consequently, production compliance.
Contractual power supply security
Analysis of your contracts to incorporate supply quality clauses tailored to the requirement for absolute continuity.
HVAC running 24/7
Keeping air conditioning and ventilation running continuously has a lasting impact on your energy bill, regardless of daily production volume.
Contract and subscribed power assessment
Recalibrating subscribed power based on actual site operations, without ever interfering with the cleanroom's control systems.
Quality and energy obligations viewed as linked
Quality teams (ISO 13485, GMP) and procurement and energy teams often work in silos, without a shared vision of energy management.
Dedicated point of contact, procurement, and management
A single consultant who understands your continuity requirements and works alongside your quality teams without replacing them.
Contractual and data expertise
Optimizing and managing energy contracts for your medical plastics sites
From air handling units to injection molding presses, Sirenergies supports you with electricity and gas for your controlled-environment workshops. Our consultants work on contracts, delivery, and data, never on the validated parameters of your cleanrooms.
Contractual and capacity audit
Analysis of your electricity and gas contracts, their expiration dates, and your subscribed power levels, along with an annual review of excise duties and energy savings certificates (CEE) related to air treatment.
Purchasing strategy and competitive bidding
Consultation with our partner suppliers using specifications that distinguish between the permanent cleanroom base load and the variable press consumption, followed by a clause-by-clause comparison and negotiation prepared with you until signature.
Distribution optimization (TURPE / ATRD)
Subscribed power and TURPE options adjusted to a very steady electrical profile, daily ATRD capacity reviewed for air treatment boilers, and procedures managed with network operators.
Cleanroom tariff modeling
Simulation of the cleanroom energy budget based on various hedging strategies, price risk analysis, and feasibility studies for a PPA (Power Purchase Agreement) or photovoltaic self-consumption tailored to a stable base load.
Pilott software platform
D+1 consumption data for your sites, carbon footprint tracking, budget forecasting, and centralized contractual documents, with CSV or API export to your reporting tools.
Expert consulting dedicated to medical devices
A consultant who understands your continuity constraints, monitors markets and regulations (excise duties, capacity mechanisms, CEE), and builds energy, budget, and environmental indicators with your teams.
Our platform
Pilott, simplified management to track your consumption
- Bring your production sites and their meters together in one space

Methodology and definitions
What is energy consulting for medical plastics manufacturing?
At night, a cleanroom consumes almost as much energy as it does during the day: this is what sets a medical plastics site apart from a standard workshop. Energy consulting here involves paying the right price for the delivery costs of such a consistent profile—TURPE (the tariff for using public electricity networks) for presses and ventilation, and ATRD (third-party access to gas distribution networks) for fresh air—and then providing support for purchasing both energy types. Sirenergies consultants use the Pilott platform to achieve this.
The context
As of August 1, 2026, the TURPE for sites connected to medium and low voltage increased by an average of 3.04% (CRE, deliberation no. 2026-105 of May 21, 2026). A flat profile can only be protected against this by paying for the correct power capacity.
Our method
- Subscribed power levels adjusted to a stable baseline, without paying for a safety margin all year round.
- Connection and continuity clauses reviewed with your technical partners.
- The impact of every adjustment made by your quality teams tracked on a daily basis.
What does a year of cleanroom operations really cost your site?
Your invoices and load profile are all we need to isolate this baseline and calculate the potential savings. No obligation.
