B2B energy procurement strategy: how businesses can reduce costs

In a modern company’s budget, energy expenditure is no longer a fixed cost to be passively accepted, but a strategic variable to be managed with expertise. For a Chief Financial Officer (CFO) or a Purchasing Manager, mastering energy procurement strategies means directly impacting operational efficiency (Opex) and business competitiveness.

In our previous article on the cost of energy and the PUN, we analyzed market dynamics; here, we will get straight to the point. Let’s look at the strategic levers a company can use to optimize its energy purchases in the liberalized market.

Lever 1: the strategic dilemma – fixed vs. variable price

The choice of contract type is a fundamental decision that determines the level of risk and predictability of expenditure. There is no single correct answer, but rather a strategic choice based on the company’s profile.

Fixed Price: the “defensive” strategy

Locking in the price of the energy component for 12–24 months means prioritizing budget stability and certainty.

• Ideal for: companies with low margins, constant production processes, and a low tolerance for risk.
• Advantage: precise financial planning without surprises.
• Drawback: does not allow you to benefit from potential market price drops, potentially paying a premium for security.

Variable Price (indexed to the PUN): the “offensive” strategy

Tying your cost to the PUN (Single National Price) means betting on your ability to absorb volatility in order to seize market opportunities.

• Ideal for: flexible companies with a good understanding of the market or with modulable processes (e.g., concentrating consumption when the PUN is lower).
• Advantage: potential to benefit from market downturns.
• Drawback: exposure to sudden cost spikes; budgeting becomes more complex and risky.

Lever 2: timing is everything – market monitoring

Buying energy is no different from buying other raw materials: the timing of the purchase is crucial. The most well-structured companies don’t just renew contracts at expiration. They actively monitor the market, including forward prices (futures), to:

• Anticipate trends: identify the most favorable moments to sign a fixed-price contract.
• Negotiate from a position of strength: approach suppliers with full awareness of market conditions.
• Plan multi-year budgets: use projections to build reliable cost scenarios.

Lever 3: advanced strategies – diversification and PPAs

For larger, energy-intensive companies, there are more sophisticated tools to manage energy procurement.

• Mixed Portfolio: It is not necessary to choose 100% between fixed and variable. It is possible to structure contracts that cover part of the energy needs at a fixed price (to guarantee the production base) and leave a portion at a variable price (to seize opportunities).
• Power Purchase Agreement (PPA): These are long-term supply contracts (10-15 years) signed directly with a renewable energy producer. The company secures a fixed, stable price for a portion of its energy, completely decoupling from market volatility and ensuring a 100% green supply.

The ultimate strategy: stop buying, start producing

No matter how sophisticated procurement strategies are, they are a response to optimizing spending within a market you cannot control. The winning move, however, is to change the rules of the game.

The installation of an industrial solar PV system on your facility’s roof represents the most powerful long-term strategy. It means becoming your own energy producer at a fixed, predictable, and near-zero cost for over 25 years.

Self-consumption drastically reduces the amount of energy that needs to be purchased, making the company immune to PUN volatility and complex market negotiations for an ever-increasing portion of its energy needs.
