  • Reporting and presentations. Produce clear, high-quality analysis, reports and presentations, turning complex data into decision-ready recommendations.
  • Commercial support. Support commercial negotiation activity with development partners, key suppliers, financial institutions, and technical, legal and market advisors.
  • Stakeholder collaboration. Work with internal and external stakeholders to analyse project performance, identify areas for improvement, and provide recommendations for strategic decision-making.

What You'll Bring

  • Background in investment banking, consultancy, infrastructure, energy, project finance or a similarly analytical commercial environment
  • Strong analytical and problem-solving ability
  • Data analysis, financial modelling and report preparation skills
  • Strong proficiency with AI tools and a clear interest in using them responsibly and effectively
  • Proficiency in Microsoft Excel and PowerPoint
  • Knowledge of project finance and investment analysis
  • Excellent written and verbal communication skills

About BW Energy Storage Systems

Company Overview

Name

BW Energy Storage Systems, a subsidiary of BW Group

Headquarters

Singapore

Founded

2020

Size

Approximately 30 employees (source: ess-news.com).

What They Do

BW Energy Storage Systems (BW ESS) specializes in battery energy storage systems (BESS), acting as a developer, owner, and operator of utility-scale projects that enhance energy market efficiency, integrate renewable energy sources, and stabilize electrical grids. The company focuses on large-scale BESS platforms that utilize advanced liquid-cooled technologies, such as Sungrow’s PowerTitan 2.0, which provide essential grid-forming capabilities including black start, millisecond inertia support, and frequency/voltage stabilization (source: bw-ess.com). These systems are designed for durations of up to 3.5 hours, enabling revenue generation through tolling agreements, frequency response, and energy arbitrage, particularly in deregulated energy markets across Europe and Australia (source: bw-group.com). BW ESS's strategic focus on long-term asset ownership rather than merchant sales allows it to serve grid operators, utilities, and energy traders effectively (source: bw-ess.com). The company leverages its backing from BW Group for funding and maritime expertise, which enhances its capacity for rapid project execution and innovative revenue models, positioning it as a leader in the energy storage sector (source: bw-group.com).

Projects & Track Record

As of early 2025, BW ESS boasts over 500MWh of operational BESS projects and more than 1GWh currently under construction, alongside a robust 7GW development pipeline (source: bw-group.com). A flagship project is the 100MW/331MWh Bramley BESS located near Bramley, Hampshire, UK, which became operational in early 2025, marking it as the largest battery energy storage system in the UK at that time and capable of powering approximately 44,000 homes daily (source: bw-group.com). Other significant projects include the Hams Hall site in the UK, which is currently under construction with a capacity of 1.4GWh, and the Berkswell site, which is at the ready-to-build stage (source: cbinsights.com). The company is also engaged in a 700MW/3.5-hour BESS portfolio in the UK, a 1.5GW collaboration with Zelos Energy in Germany, and multiple projects in Italy and Australia, significantly expanding its geographic footprint and operational capacity (source: bw-ess.com). Key clients include Shell Energy Europe, with whom they have a 7-year tolling agreement for the Bramley project, and partnerships with local developers to facilitate market entry (source: bw-group.com).

Recent Developments

In February 2025, BW ESS celebrated the inauguration of the 100MW/331MWh Bramley BESS, marking its first European project with Sungrow PowerTitan 2.0, under a groundbreaking 7-year tolling agreement with Shell Energy Europe established in 2024 (source: bw-group.com). In October 2024, the company made headlines by acquiring the remaining shares of Penso Power, thereby merging its team of nearly 30 specialists and adding a significant 2GW pipeline of projects in the UK and Australia, which contributed to a total pipeline of 5GW (source: ess-news.com). Additionally, BW ESS secured a 1.4GWh supply deal with Sungrow for the Hams Hall project and advanced joint projects in the UK and Italy (source: cbinsights.com). Recent announcements in 2025 included AIP Management acquiring a 49% stake in a 700MW/3.5-hour UK BESS portfolio and a collaboration with Zelos Energy Developments for a 1.5GW project in Germany (source: bw-ess.com). The Bramley project has been recognized as a significant milestone for enhancing UK grid resilience (source: bw-group.com).

Working There

BW ESS is actively hiring across various roles including project development, engineering, commercial operations, and business development, particularly following the integration of Penso Power in 2024, which enhanced their team with specialists focused on delivery and market entry (source: ess-news.com). The company is focusing its recruitment efforts on project sites in the UK, Australia, Italy, Germany, and Sweden, with a global team of nearly 30 supporting its multi-market expansion (source: bw-group.com). The culture at BW ESS is characterized by close-knit collaboration, as highlighted by CEO Erik Strømsø, who refers to the Penso teams as "trusted colleagues," fostering synergies in a fast-paced environment that navigates complex grid codes and local strategies (source: youtube.com). While specific benefits such as salaries or perks are not publicly documented, the long-term owner-operator model suggests a degree of stability tied to BW Group's extensive infrastructure expertise (source: bw-ess.com). Job seekers are encouraged to monitor LinkedIn for openings in Singapore and Europe as the company scales its operations to meet growing demand (source: linkedin.com).
