A VIVAL store manager cut his energy costs by more than 20% thanks to a contract review and supplier tendering.
Bruno Skrzypinski
Manager, VIVAL (convenience store)
1. The context
1.1 A heavy and unpredictable cost item
For a convenience store such as a VIVAL grocery, energy is a structural cost that is hard to control.
Cold rooms, lighting, ovens: consumption never stops, and energy markets are volatile.
Bruno S. puts it plainly:
“Between the cold rooms, the lighting and the ovens, energy is one of my heaviest and most unpredictable costs.”
With supplier offers multiplying, he no longer knew whether he was paying a competitive price, or how to check it on his own:
“It had become impossible to know whether I was paying the right price.”
2. The Sirenergies approach
2.1 End-to-end support from Sirenergies
Bruno S. needed an expert able to analyse his actual consumption and support him through supplier tendering.
What stood out for him in the support he received:
“Clear explanations of the taxes and network charges (...) and fast supplier tendering to get the best terms available at the time.”
- 1
Consumption review
Detailed analysis of the store's energy scope: equipment, operating hours, current contracts.
- 2
Clear explanation of pricing
Clear explanations of how invoices are built: network charges, taxes, variable components.
- 3
Fast supplier tendering
Several suppliers consulted at the same time to obtain the best terms available when the tender is run.
Sirenergies supported him from start to finish: contract review, clear pricing explanations and preparation of the negotiation.

3. The results
“The verdict is clear: Sirenergies helped me save more than 20% on my overall energy budget.”
Bruno Skrzypinski, VIVAL store manager
3.1 More than 20% savings reinvested in the store
Without changing his organisation or his equipment, Bruno S. achieved substantial savings on his overall energy budget.
These savings now allow him to reinvest directly in his business. As he puts it:
“These direct savings let me look to the future with more peace of mind.”
Key takeaway
What this case study teaches franchisees and independent retailers
The complexity of energy markets puts small, isolated buyers at a structural disadvantage. Working with a specialist advisory firm helps restore a balanced position in negotiations and gives access to pricing expertise that is not available in-house.
“I highly recommend Sirenergies to all franchisees and independent retailers who want to take back control of their bills.”
