How can block and spot contracts be combined to optimize your energy purchases in an unstable market?
Faced with the volatility of electricity and gas prices, companies are looking for flexible solutions that allow them to secure part of their budget while taking advantage of occasional market opportunities. The combination of block and spot purchases provides an appropriate response to these challenges, balancing volume coverage with agility in risk management.
Josepha Fleury, Senior Energy Manager, and Laurent Hornez, Associate Director Energy, share their insights and practical advice on how to define a hybrid strategy tailored to your consumption profile and financial objectives.

When CSR is taken into account, renewable energies emerge as a theoretically attractive alternative to today’s business challenges.
