ROLE MANDATE:

The Lead – Systems Integration owns the BESS as an integrated electrical and control system — how the product and its components behave together, and how that combined system behaves against the grid. Where Product Engineering owns the box, this role owns everything the box has to talk to.
The mandate has two halves. First, system and grid integration authority — governing the BMS / PCS / transformer / MV switchgear / EMS / SCADA / plant-controller interface stack, grid-code compliance, protection and controls philosophy, and all power-system studies up to the point of interconnection. Second, electrical design review authority — the technical sign-off gate for electrical design from the DC block onwards through AC collection, auxiliary power and the POI, whether the design originates in-house, from an EPC contractor or from a design consultant.

KEY RESPONSIBILITIES:

Grid Integration & Compliance
Own grid-interconnection technical compliance — CEA connectivity and technical standards, IEGC / CERC regulations, state grid codes and RLDC / SLDC telemetry,



metering and scheduling requirements
Define and govern grid-support functional requirements — LVRT / HVRT ride-through, frequency response and FFR, active-power ramp control, reactive power and voltage regulation at POI, power-factor and Q-at-night capability
Own the power-system study pack — load flow, short-circuit, protection coordination, harmonic and power-quality (IEEE 519 / IEC 61000), insulation coordination, earthing and lightning protection, arc-flash, and EMT / energetic grid-compliance simulation (PSCAD / PSS®E / ETAP / DIgSILENT)
Own the plant-controller (PPC) functional specification and the set-point hierarchy between EMS, PPC and PCS — including mode arbitration, curtailment logic and hybrid / FDRE co-ordination with wind and solar
Drive grid-compliance studies, connectivity approvals and utility clarifications on the tender and project critical path
