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 grid-connected 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, decision-ready recommendations and deliver high-quality 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
• Owner's 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 (Consulting-Oriented)

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 punch-list support and technical closure guidance.

4) Documentation Quality, Governance & Risk

• Create high-quality 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 single-line 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 grid-connected assets (BESS, renewables, substations, industrial power).
• Ability to operate credibly with clients and external stakeholders while retaining hands-on 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 AR-N 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 decision-grade documents under time pressure.
• Commercial awareness: scope definition, change control, proposal input, value-based recommendations.
