Partnering to Build Tomorrow's Energy Systems

We work with technical, commercial, and public partners to deliver reliable energy infrastructure that supports today’s grid and enables tomorrow’s renewable energy system.

Working Together

Integrity and reliability is one of S4’s core values. What that means is we do what we say and deliver what we promise – that’s why we have delivered all of our projects to date on time and within budget. We work with our partners with full transparency and care, and take ownership for our work. When you work with S4 you should expect to combine technical precision with hands-on experience.

Technical Partners

Technical standards

S4 Energy aspires to embody sector-leading standards and reporting. We are formalising our controls environment and compliance with ISO standards across HSE, sustainability, cybersecurity, and others, and expect the same from our partners. Our standards reflect those of a leading pan-European IPP, and work with tier 1 partners across all our projects.

What we look for in partners

We look for partners who share our values and are focused on building long-term relationships to last decades. We have ambitious goals and want partners with the same hunger and scale to address the significance of the energy transition – our pipeline is >20GWh, and we need partners who are excited by the scale of this challenge. We are willing to collaborate across the full BESS value chain with any supplier, developer, constructor, or operator who shares our high standards, and are actively acquiring projects across all our core markets. We do not believe in one-size-fits-all, or one-technology-fits-all as shown by our history and are open to any proposal to collaborate.
