BW ESS is looking for a BESS Asset Manager for Germany to take ownership of the performance, commercial optimisation, and operational management of our German battery energy storage assets.
This role is suited to someone with a blend of technical and commercial experience: a person who understands how utility-scale battery or power assets perform operationally, how they generate value in energy markets, and how to manage contracts, data, counterparties, and regulatory requirements across the full asset lifecycle.
We are especially interested in candidates with experience in utility-scale BESS, renewables, grid infrastructure, power markets, or energy asset management, ideally with exposure to the German energy market.
About BW ESS
BW ESS is a global energy storage owner-operator, moving with speed to develop, deliver, and operate market-leading projects.
The business is active in the UK, Australia, Italy, Germany, Spain, and Sweden. It has more than 540MWh of operating Battery Energy Storage Systems, with approximately 12GWh under construction and a development pipeline of several gigawatts.
Part of BW Group, BW ESS builds on decades of global infrastructure experience, takes a long-term view of projects and partnerships, and focuses on unlocking value throughout the energy storage asset lifecycle.
The Role
As BESS Asset Manager, you will be responsible for the operational and commercial performance of utility-scale battery assets in the German market, with potential exposure to a wider European portfolio.
You will work across asset performance, route-to-market optimisation, contract management, budgeting, warranty management, regulatory compliance, and site integration. You will collaborate closely with German and international colleagues, RTM providers, optimisers, OEMs, O&M contractors, EPCs, TSOs/DSOs, and other market counterparties.
The role sits at the intersection of technical asset management, commercial optimisation, energy markets, and regulation. You will help ensure BW ESS’s German portfolio is positioned to perform across products such as FCR, aFRR, mFRR, intraday and day-ahead markets, and other relevant flexibility or capacity mechanisms.
Key Responsibilities
-
Manage and monitor the performance, availability, degradation, cycle counts, and operational health of utility-scale BESS assets.
-
Analyse SCADA, EMS, and asset data to identify underperformance, diagnose root causes, and coordinate corrective actions with technical teams and service providers.
-
Work with route-to-market providers and optimisers to monitor and improve commercial performance across German balancing and wholesale markets.
-
Support and oversee optimiser, O&M, OEM, EPC, and other service provider contracts, ensuring obligations and KPIs are met.
-
Review invoices, manage budget inputs, support OPEX/CAPEX tracking, and contribute to medium- and long-term cost and revenue forecasting.
-
Maintain warranty registers, monitor warranty periods, coordinate claims, and manage related documentation and stakeholder processes.
-
Support commissioning, control system setup, EMS/software integration, data validation, testing, and handover into operations.
-
Track relevant German and EU regulatory developments, including BNetzA, TSO/DSO requirements, EEX, grid codes, and market rule changes.
Experience We’re Looking For
We are looking for candidates who can bring both technical credibility and commercial judgement.
You should ideally have:
-
3+ years’ experience in utility-scale BESS, renewables, grid infrastructure, power generation, energy asset management, or a closely related field.
-
Experience managing or supporting operational energy assets, ideally in Germany or another European power market.
-
Understanding of battery systems, lithium-ion technology, inverters, BMS, EMS/SCADA, grid connections, and asset performance metrics.
-
Commercial exposure to energy markets, route-to-market arrangements, optimisation, balancing markets, intraday/day-ahead trading, or asset revenue management.
-
Familiarity with German energy market structures, TSOs, DSOs, BNetzA, EEX, grid codes, and ancillary service products would be highly valuable.
-
Experience working with data tools such as PowerBI, SQL, Excel, or similar platforms.
-
Strong contract management, reporting, stakeholder management, and problem-solving skills.
-
Excellent written and spoken German and English.
A degree in electrical engineering, energy systems, or a related technical or commercial discipline would be beneficial, but relevant hands-on experience is equally important.
