For individuals, the equation is often simple: a natural gas or electricity contract = a consumption site. For businesses, communities and professionals, the calculation can be a bit complicated. An energy contract can be said to be “multi-site”. It then combines the energy supply of several sites, such as several laundries, several restaurants or several warehouses for example.
Centralizing its energy supply contracts into a single agreement reinforces operational efficiency and negotiating power. This solution simplifies administrative management with a single invoice. It also makes it possible to save money by benefiting from the same pricing conditions for all sites. How to properly negotiate and manage a multi-site contract?
Our advice.
Whatever your sector of activity, the size of your company or the type of your counter, you must first of all define a purchasing strategy adapted to your challenges.
The secret to a good negotiation?
Know your needs and consumption profile perfectly. Good preparation is the prerequisite for write clear, precise and exhaustive specifications and obtain the most competitive offer.
The first step is to precisely clarify your needs and to define the scope of the multi-site contract.
To define the scope of the multi-site contract, you must:
Negotiating a single supply contract for all of a company's sites requires centralizing all administrative and technical data, as well as existing invoices, in advance.
You need to:
Collecting electricity and gas data and bills is a tedious, time-consuming task and has no added value. You can simplify this step by hiring an energy consulting firm.
SirEnergies centralizes all of your sites and archives your data in a single customer area. This unique platform facilitates access to all your information (electricity and gas contracts, amendments, invoices, energy consumption, etc.).
Each business is unique. Each site has a specific consumption profile. Before negotiating your multi-site energy contract, you must establish a clear and adapted purchasing strategy:
Negotiating a multi-site contract is a long and complex process. Calls, emails, reminders, multiple identifiers and passwords for each customer area of each supplier: the barriers are numerous. Here are some tips for effectively negotiating your energy contract if you manage a multi-site business.
Prices change daily.
The electricity and natural gas markets are European exchanges where prices fluctuate every day depending on many factors (supply level, demand level, geopolitical factors, CO2 certificate price, oil price, etc.)
For se position at the right time, it is important to monitor daily, observe trends and anticipate upward and downward developments.
Not every energy supplier is right for your business.
Some electricity and gas suppliers are better positioned on small multi-site consumers and others on large single-site consumers. It is therefore necessary to choose the suppliers the better adapted to your typology. You can also, to improve your carbon footprint and your CSR policy, prefer to sign a contract with a local supplier or a supplier committed to green energy.
1 day can make a difference. Once the specifications have been sent, you must ask for the same response date from all suppliers in order to be able to compare prices with the same quotation day.
Comparing offers is the critical step. It is essential to draw up a comparative table of contractual conditions and prices offered by all energy suppliers. The breakdown of prices will avoid an unpleasant surprise and will allow you to distinguish between really fixed prices and those likely to change during the contract.
The multi-site contract must correspond to your specific needs and your consumption profile. If money is the lifeblood, other clauses — other than pricing — should draw your attention to optimize your budget:
It's time to sign. The longer you ask for the validity of the offer, the more your price will be degraded. In fact, the supplier's risk taking to keep the price on the market for one, two, three days or more will be passed on to you.
Negotiation is a complex process.
It requires a perfect knowledge of the electricity and gas markets, a great deal of expertise to understand pricing offers and a great deal of responsiveness.
The experts of SirEnergies support you in your negotiation to seize the best opportunities and subscribe to the contract with the best quality-price ratio!
Once the multi-site contract is signed, your objective should be to keep control of your consumption, your bills and your electricity and gas budget.

Le dispositif ARENH a laissé place au VNU (Versement Nucléaire Universel).
Ce changement structurel expose davantage les entreprises aux prix de gros, rendant la gestion des risques plus complexe qu'auparavant.
Il devient alors indispensable de définir une stratégie d'achat d'électricité avec Sirenergies pour lisser l'impact de la volatilité des marchés sur votre budget.

C'est le levier le plus rapide pour obtenir des résultats visibles. L'éclairage représente environ 40 % de la consommation d'électricité d'une commune.
Passer au LED avec pilotage intelligent permet de réduire la facture de 50 à 80 %, avec un retour sur investissement (ROI) rapide, souvent estimé à 2 ou 3 ans.

Même le bâtiment le plus moderne et le mieux isolé perd son efficacité si ses usages sont inadaptés. La technologie et les normes ne suffisent pas : la transition énergétique est avant tout une transformation humaine.
Derrière chaque kilowattheure consommé se cache une habitude.
Un collaborateur sensibilisé comprend qu'ouvrir une fenêtre alors que le chauffage est allumé ou laisser un ordinateur en veille consomme de l'énergie inutilement. En replaçant l'humain au centre de la stratégie de gestion de l'énergie, l'entreprise s'assure que ses équipements performants sont utilisés de manière optimale, garantissant ainsi une rentabilité durable et un impact environnemental réduit.
