What They Do

OX2 is a prominent renewable energy developer that specializes in wind power, having established its foundational expertise in this area since its inception in 2004. The company has developed and initiated construction on approximately 3.9 GW of onshore wind projects aimed at industrial and institutional customers, while also expanding its portfolio to include offshore wind, solar power since 2018, and energy storage solutions such as battery energy storage systems (BESS) (source: ox2.com). OX2 provides comprehensive end-to-end services across the renewable energy value chain, which encompasses financing, permitting, construction, technical and commercial management, and the sales of turnkey projects. This includes notable hybrid projects like the 119 MW solar plus 100 MW BESS SEC Renewable Energy Park Horsham in Australia (source: ox2.com). The company targets markets across Europe and Australia, catering to industrial customers, institutional investors, and utilities through power purchase agreements (PPAs), including significant contracts with major corporations like Google (source: renewables.digital). OX2 has established itself as Europe's leading developer of large-scale onshore wind projects since 2015, with over 3.2 GW developed and sold historically, leveraging its full value-chain integration and competitive pricing strategies (source: peas.com).

OX2 has successfully completed numerous notable projects across Europe and Australia, including a variety of onshore wind farms such as Riberget in Ljusdal, Sweden; Ribäcken in Maalahti, Finland; and Rustari in Kurikka, Finland. Other significant projects include solar initiatives like the Ross River Solar Farm in Townsville, QLD, Australia, and the Wyalong Solar Farm in Wyalong, NSW, Australia (source: ox2.com). Currently, OX2 is engaged in major projects such as a 277 MW onshore wind initiative in Finland, which recently commenced construction, and several wind and battery storage projects in regional Western Australia. The company is also developing onshore wind projects like Skarpen in Ljusdal, Sweden, and Ukonpalo in Kuusamo, Finland, alongside solar projects like the Summerville Solar Farm in Rappville, NSW, Australia (source: renewables.digital). OX2's strategic partnerships with clients such as Google and Ellevio for offshore wind projects further solidify its competitive position in the renewable energy sector (source: renewables.digital).

Recent Developments

In the past two years, OX2 has made significant strides in its project portfolio, including the initiation of construction on a 277 MW onshore wind project in Finland and the acquisition of three wind power projects in Romania. The company has also secured contracts for major wind and battery storage projects in Western Australia and completed its first BESS in southern Sweden in 2024, while divesting another in Finland (source: ox2.com). Additionally, OX2 expanded its footprint by purchasing over 500 MW of solar and wind projects in Greece in March 2022, further enhancing its operational capabilities in the region (source: renewables.digital). In 2024, EQT Infrastructure VI made a strategic investment in OX2 to support its transition towards becoming an asset owner, which is expected to bolster the company's growth trajectory in the renewable energy sector (source: eqtgroup.com).

Job Description

The Storage Director is a senior role within OX2's Storage organisation. The role sits at the intersection of solid technical expertise and commercial acumen, and ensures that OX2 approaches Battery Energy Storage Systems (BESS) across the full project lifecycle with a well balanced technical-commercial approach ultimately aimed at optimizing OX2's BESS operational performance.

A special focus area of this role will be to ensure both operational readiness as well as strong performance for OX2's BESS projects. This includes working with others to successfully deliver pre-operational activities such as ancillary services prequalification or SAT audits, as well as operational activities such as defining BESS operational strategies, backcasting, monitoring optimizer performance or conducting shadow-trading of our BESS assets. BESS analytics and identifying OX2's target partners and software solutions and tools will also be essential.

By combining input from the technical, procurement, offtake, power markets, investments, digital and country teams, the Storage Director serves as a key driving force that completes key steps in OX2 Storage's strategy and project delivery process. The role is also critical in working around IT/OT integration solutions for BESS, as well as identifying technology trends (e.g. on batteries or automation) that translate into a commercial advantage for OX2.

The role is a multidisciplinary position and requires both leading as well as supporting other functions, such as Construction or Asset Management/IPP, with potential engagement earlier in the process (e.g. during Offtake or Realization/Transactions).

The Storage Director leads through influence and expertise - setting the direction for storage technology strategy, challenging assumptions, and bringing together stakeholders from across the organisation to drive better outcomes. The role demands curiosity, rigour, and a genuine willingness to explore new approaches as the market, regulation, and technology landscape evolve.

This is a role for someone who is as comfortable in a technical deep-dive as they are in a commercial negotiation or a cross-functional steering meeting - and who thrives in an environment where collaboration, initiative, and intellectual honesty are valued over hierarchy.

Qualifications & Experience

Required

  • Minimum 10 years of experience in energy storage and/or the broader renewable energy sector.
  • Deep, hands-on knowledge of BESS technology across multiple parts of the value chain - including development, engineering, procurement, construction, and/or operations.
  • Proven experience in BESS trading, battery analytics or overall BESS asset performance monitoring.
  • Strong technical foundation (system architecture, battery technology, construction, grid integration, performance monitoring, operations) combined with genuine commercial and business acumen.
  • Strong commercial mindset with proven experience with customers, as well as connecting commercial and technical aspects into an optimal solution.
  • Demonstrated ability to lead cross-functional initiatives and influence - often without direct authority.
  • Proven experience working across multiple markets and with multicultural, multidisciplinary teams.
  • Bachelor's or Master's degree in Engineering or a closely related technical discipline.
  • Excellent communication skills - able to convey complex technical and commercial concepts clearly to a range of audiences, including senior leadership and external partners.
  • Proficiency in English is a must; additional languages are an advantage.
  • Ability to travel internationally (~20% of the time).

Personal Attributes

  • Intellectually curious and open-minded - willing to challenge the status quo, question assumptions, listen to alternative perspectives and learn.
  • Collaborative and collegial, with a natural instinct to bring people together rather than work in silos.
  • Pragmatic and solutions-oriented, with a strong focus on delivering quality outcomes.
  • Flexible and comfortable with ambiguity, as well as able to operate effectively in a fast-moving, evolving environment.
  • Driven and proactive, with a genuine passion for the energy transition and the role of storage within it.
