Modular Power POD's & Solutions

Leading the Data Centre Industry with our Revolutionary e-POD

The Data Centre e-POD is a modular, package, fully designed to get DC developers scaling faster, with minimised risk

Our Data Centre e‑PODs are available in two distinct formats, giving customers complete flexibility over how their critical power infrastructure is delivered. Building on years of experience providing fully bespoke, vendor‑neutral modular power solutions, we continue to offer custom‑engineered e‑PODs tailored precisely to each client’s specification, using any preferred combination of components. Alongside this, we now also offer our in‑house Rehlko Basecore e-POD range – a standardised, fully engineered modular package that utilises Rehlko’s own integrated product range to deliver a streamlined, high‑performance solution. Both options are designed, packaged, installed and commissioned by our expert in‑house team, ensuring customers can choose between a truly bespoke, vendor‑neutral system or a fully optimised Rehlko-engineered e-POD that reduces complexity while maintaining exceptional reliability.

Bespoke ‘Vendor-Neutral’ e-POD Solutions

Our vendor‑neutral e‑POD solution offers complete design freedom, enabling us to engineer fully bespoke modular power systems built entirely around each client’s preferred technologies, components, and operational requirements. Every package is tailored from the ground up—whether that means integrating specific generators, switchgear, controls, fuel systems or ancillary equipment—ensuring total alignment with the client’s existing infrastructure, standards and strategic goals. This approach gives customers the highest level of flexibility, customisation and future‑proofing, with all design, packaging, installation and commissioning carried out in‑house by our specialist engineering teams.

Rehlko BaseCore Pods

For clients seeking a streamlined, fully integrated modular power package, our Rehlko BaseCore Pods provide a high‑performance, in‑house engineered alternative. Designed and manufactured using Rehlko’s own product ecosystem, BaseCore Pods offer a consistent, optimised configuration that shortens lead times, simplifies coordination and ensures seamless component compatibility. Each unit is pre‑designed, packaged, installed and commissioned by our in‑house experts, delivering a robust, plug‑and‑play critical power solution that reduces complexity while maintaining exceptional reliability and operational efficiency.

Switchgear e-POD

The e-POD switchboard container is the heart of the system and will be designed to totally reflect the power distribution requirements of the site and application. The e-POD concept provides the space and flexibility of design to accommodate all power distribution options be they 100% generator / UPS support for the load or a mixed essential non-essential distribution arrangement.

The switchgear POD has fully segregated MV and LV areas which are cooled or ventilated as required. The transformer and RMU area of the switchboard POD has fan assisted cooling and weather louvers. The ventilation system for RMU and transformer space is via the double louvered access doors. The louvres are suitably sized to ensure that there is adequate makeup air into the space. The cooling air is mechanically extracted via a single louvre.

    lighting (inc emergency lighting)
    – BMS/EMS Central hub
    – Access stairways and external lighting
    – Access control as required

  • Fire Suppression

    Fire suppression equipment can be installed in all e-Pods, built to client specification. The selected fire suppression system can either be sourced locally or centrally as required.

UPS e-POD

Each “UPS e-POD” can include a UPS(s) rated to meet the specific requirements of the project. UPS packages typically come complete with high quality, stand mounted 10 year design life batteries offering a full 10-minute end of life autonomy or to meet the project requirements. The battery system also includes a battery circuit breaker and string isolation.

As a vendor neutral solution, the selection of UPS(s) manufacturer is open for the client to choose. As with all other aspects of the e – POD packages WB are able to both advise and draw on their group of top global manufacturers to find a solution to meet the requirements of the specification. WB would typically look for a high efficiency double conversion UPS design which completely isolates output power from all input power anomalies, and delivers 100% conditioned, perfect sine-wave output, even during severe power disturbance. Space is available in the container for either a single or parallel redundant UPS.

The battery system, which will be housed in a separate temperature controlled area can be complimented with full DC protection as well as inter tier protection/ isolation and battery monitoring systems. Where required all ancillary services within the WB e-Pods can be supported by a smaller UPS with integral bypass, battery circuit breaker and 10 minute battery system.
