Critical & Secure Facilities

Energy resilience for sites where the wrong hardware choice is a security risk.

Independent energy infrastructure advice for critical facilities, secure estates, healthcare, data centres, and emergency services — where power continuity, hardware provenance, and data sovereignty are as important as cost and carbon.

The problem most assessments miss

The energy system you install may create the security vulnerability you didn't know you had.

Most cleantech feasibility assessments focus on yield, payback, and procurement route. Very few address the security implications of the hardware being specified — and for critical and secure facilities, this is a serious gap.

Solar inverters, battery management systems, energy monitoring platforms, and SCADA-connected devices from certain manufacturers — particularly those produced in China — are built with default configurations that route operational data to overseas servers. This data can include real-time consumption profiles, grid connection topology, generation output, system status, and in some architectures, remote access credentials that could allow external parties to interact with control systems.

For a retail warehouse this may be a manageable risk. For a hospital, an emergency services facility, a government estate, a data centre, or a defence supply chain site, it is a procurement issue that needs to be addressed before a single piece of equipment is ordered.

We advise on hardware security, network architecture, and data sovereignty as a standard part of every engagement with critical and secure facilities — not as an optional add-on.

What we assess beyond standard feasibility

  • Country of manufacture and data routing behaviour of specified hardware
  • Default telemetry configurations and how to disable or control them
  • Network segmentation requirements for energy management systems
  • Remote access architecture and authentication controls
  • Integration points between energy systems and wider IT/OT infrastructure
  • Procurement framework requirements for hardware provenance
  • Contractual obligations around data handling with equipment suppliers

This is not a theoretical risk. Multiple national cyber security agencies have issued advisories about connected energy infrastructure hardware from non-European manufacturers. UK public sector organisations and critical national infrastructure operators should treat hardware provenance as a procurement requirement, not a preference.

Advisory services

What we do for critical and secure sites.

Our work with critical and secure facilities combines energy resilience advisory with a level of security awareness that standard cleantech consultants do not apply. The result is energy infrastructure that is not only technically sound and commercially viable — but safe to operate in sensitive environments.

Energy security risk assessment

A structured review of your current and planned energy infrastructure against security criteria — identifying hardware with problematic data routing, network vulnerabilities in connected energy assets, and gaps in your operational resilience posture.

Critical power & backup strategy

Assessment of your critical load requirements, backup generation options, battery storage for bridging and resilience, and the right combination to maintain essential operations during a grid outage — sized and specified against your actual continuity requirements.

Microgrid & islanding design

For sites where grid independence is a requirement, we design islanded microgrid architectures combining solar, storage, and backup generation — with islanding protection specified to meet your operational continuity and safety requirements.

Cyber-aware controls & network architecture

Controls system specification and network architecture designed with security in mind from the outset — covering network segmentation, remote access controls, authentication architecture, and integration with existing IT and OT security frameworks.

Secure procurement specification

Procurement documentation that embeds hardware provenance requirements, data handling obligations, security testing criteria, and supply chain transparency requirements — so security criteria survive from specification through supplier selection to contract.

Existing infrastructure review

Assessment of energy systems already installed — inverters, monitoring platforms, building energy management systems, and connected metering — against current security standards and data routing behaviour. Identifying remediation actions where risks exist.

Sectors we serve

Organisations where standard cleantech advice is not enough.

These organisations share a common requirement — energy infrastructure that is resilient, secure, and specified in a way that does not create new vulnerabilities.

Healthcare & NHS

Hospitals, GP practices, mental health facilities, and care homes where power continuity is a patient safety issue and procurement follows NHS supply chain frameworks with specific security requirements.

Emergency services

Police, fire, and ambulance stations, control rooms, and coordination centres where operational continuity during a major incident is non-negotiable and network security is a standing requirement.

Data centres & colocation

Facilities with contractual uptime guarantees where energy cost, resilience, and sustainability commitments all need to be met simultaneously, and where connected infrastructure is a known attack surface.

Government & public sector estates

Central and local government buildings, MOD supply chain, HMRC, DVLA, and other estates with data handling obligations, procurement rules on hardware origin, and net zero targets to meet.

Defence supply chain

Tier 1 and Tier 2 defence contractors whose facilities handle sensitive material and operate under supply chain security requirements that affect what hardware can be specified and from whom.

Water & utilities infrastructure

Operational technology environments where energy management systems interface with process control infrastructure and where the boundary between IT security and OT security is critical to maintain.

How we work

A process shaped around your security requirements.

1

Confidential initial consultation

We start with a confidential conversation about your site, your operational requirements, your current energy infrastructure, and your security constraints. We do not need sensitive operational detail at this stage — just enough to scope the work appropriately.

2

Risk & infrastructure assessment

We review your existing and planned energy infrastructure against security and resilience criteria — identifying hardware risks, network vulnerabilities, and gaps in your resilience posture alongside the standard energy assessment.

3

Options development

We develop resilience and energy options that meet both your operational and security requirements — specifying hardware from manufacturers with appropriate provenance and data handling characteristics, and designing network architecture accordingly.

4

Specification & procurement documentation

We produce procurement documentation that embeds security requirements explicitly — so they cannot be traded away during supplier negotiation or value engineering without your knowledge and approval.

5

Delivery oversight

We provide independent oversight during delivery — verifying that installed hardware matches specification, that network configurations are implemented correctly, and that security requirements have been met before handover.
