BESS Strategy & Advisory Consultant (market business models client advisory)

Role Summary

As a Consulting Electrical Engineer BESS you advise clients across the full lifecycle of gridconnected battery storage: from early-stage feasibility and grid connection strategy through concept design vendor evaluation and support during commissioning and operational optimization. You translate technical complexity into clear decisionready recommendations and deliver highquality study outputs that stand up to scrutiny from developers utilities lenders insurers and authorities.

Typical Engagements (Consulting Context)

• Feasibility & Concept Selection: technical concept screening architecture tradeoffs (AC/DC coupling MV/HV interface) risk/opportunity mapping.
• Grid Connection & Compliance Advisory: grid code requirement interpretation and compliance planning support to DSO/TSO interactions
• Owners Engineer / Independent Engineer: technical reviews design audits package specifications factory/site acceptance support.
• EMS/PPC & Controls Advisory: defining required EMS/PPC functionalities and integration expectations with protection/control infrastructure.

Key Responsibilities (ConsultingOriented)

1) Client Advisory & Study Delivery

• Lead or contribute to consulting deliverables such as feasibility studies grid connection strategies concept design reports technical specifications and risk assessments.
• Run technical workshops with clients and stakeholders; capture requirements and convert them into clear scopes assumptions and deliverables.
• Build defensible recommendations by evaluating alternatives and documenting tradeoffs (cost schedule performance compliance operability).

2) Technical Authority: Electrical & Grid Interface

• Provide expert guidance on MV/HV electrical interfaces protection philosophy and integration of BESS into existing networks.
• Support or manage power system studies with internal/external partners (e.g. grid compliance modelling) and translate results into actionable client decisions.
• Advise on grid impact topics (e.g. EMC / network effects) and what evidence is needed for compliance and permitting.

3) Vendor OEM & EPC Interface Management

• Review OEM/EPC proposals clarify technical scope and identify exclusions/risks; support tender evaluations and negotiation readiness.
• Define and review technical specifications for electrical packages (transformers switchgear protection auxiliaries) ensuring alignment with project objectives and grid code expectations.
• Contribute to FAT/SAT planning and acceptance criteria; provide punchlist support and technical closure guidance.

4) Documentation Quality Governance & Risk

• Create highquality consulting outputs: reports calculations specifications decision logs and technical presentations suited for executive and lender audiences.
• Maintain a technical risk register: safety compliance integration performance and interface risks; propose mitigations and verification plans.
• Ensure alignment with relevant standards and requirements (examples referenced in internal material include VDE/IEC/DIN and grid connection requirements such as VDE AR-N 4120/4130).

Deliverables You Will Own / Contribute To

• Feasibility / concept selection reports and singleline concept packs
• Grid connection and compliance roadmap evidence matrix
• Tender technical specification packages and bid evaluation matrices
• Technical due diligence report risk register mitigation plan
• EMS/PPC functional requirement briefs (integration with protection/control infrastructure

Required Qualifications

• Degree in Electrical Engineering / Power Systems (BSc/MSc).
• Several years experience in gridconnected assets (BESS renewables substations industrial power).
• Ability to operate credibly with clients and external stakeholders while retaining handson engineering judgement.
• Good German and English language skills written and spoken
• Willingness to travel

Technical Competencies (Consulting-Relevant)

• MV/HV systems protection concepts earthing/grounding grid interconnection interfaces.
• Knowledge of relevant standards and grid code frameworks (VDE/IEC/DIN; VDE ARN 4120/4130 referenced as relevant for grid connection requirements).
• Familiarity with BESS subsystems and interfaces: PCS transformers switchgear auxiliary services monitoring/control integration.
• Awareness of key gaps clients often have to evidence (battery technologies regulations for battery installations EMC/network effects are explicitly highlighted as areas requiring more than basic knowledge).

Consulting Skills & Behaviours

• Strong problem structuring: hypotheses assumptions and clear lines of reasoning.
• Stakeholder management: communicate with developers utilities OEMs/EPCs authorities lenders.
• Clear writing: produce decisiongrade documents under time pressure.
• Commercial awareness: scope definition change control proposal input valuebased recommendations.
