Experience

Where the judgement comes from

Erebus draws on more than twenty years of experience across contractor delivery, developer advisory, consultancy leadership and board-level governance in the UK renewable energy sector, extended through a network of specialist practitioners.

Technologies

Complex renewable energy systems

The common thread is not a single technology. It is systems where the interactions, constraints and regulatory boundaries carry more risk than any individual component.

Solar PV

Utility-scale and distributed solar, from site screening and feasibility through Owner's Engineer appointments to performance ratio and PAC test analysis on operating assets.

Battery energy storage

BESS at utility scale, including grid connection strategy, construction oversight, commissioning readiness and systems integration coordination.

Wind

Onshore wind across feasibility, technical due diligence, construction phase oversight and asset life decisions.

Heat networks

District and communal heat networks, including 5th generation systems, hydraulic design review, energy balance investigation and regulatory framing under the Ofgem heat network regime.

Grid connections

Connection strategy, queue and constraint analysis, grid reform navigation, and technical evidence for connection applications and disputes.

Hydrogen and integrated systems

Co-located and hybridised assets where the interaction between technologies drives the risk, rather than any single component.

Track record

Work that had to hold up in front of funders, regulators and courts

Representative engagements

The kind of work Erebus is called into

Client identities are withheld where engagements are commercially sensitive or ongoing.

Grid connection dispute

Technical evidence under an evolving reform process

Structured connection applications across multiple technologies during a period of substantial regulatory change, building the technical evidence base to withstand scrutiny. All submissions were ultimately successful.

Owner's Engineer

Utility-scale solar oversight

Independent technical oversight on behalf of the developer through design review, contractor change control and commissioning readiness on a large-scale solar portfolio.

Technical due diligence

Pre-investment compliance and site screening

Red-flag technical due diligence on solar PV assets, covering compliance position, site constraints and the assumptions carrying the most investment risk.

Heat network investigation

Energy balance and surplus interrogation

Independent investigation of an operating heat network where reported performance did not reconcile with the physical system, framed for regulatory scrutiny.

CDM and health and safety

Principal Designer on an industrial site

Statutory Principal Designer appointment under CDM 2015, coordinating pre-construction hazard management and health and safety file production through to handover.

Options appraisal

Heat decarbonisation for a heritage building

Fabric and heat loss assessment, electrical load appraisal, and options comparison for a heritage-constrained site, structured so the client could defend the choice made.

Feasibility

Island microgrid

Feasibility of a constrained island microgrid, where system boundaries and regulatory limits rather than generation technology determined what was viable.

Performance analysis

Portfolio underperformance review

Performance ratio and provisional acceptance test analysis across multiple operating PV assets, separating design issues from operational ones.

Depth

Built on delivery, not just advice

Advisory judgement is only worth having if it comes from people who have carried delivery risk themselves.

Consultancy leadership

Erebus is led by a director who previously held Technical & Innovation Director and Consultancy Director roles at Locogen, growing a national consultancy from 6 to 30 professionals with P&L responsibility, acting as senior technical authority on high-consequence projects and disputes.

Statutory and site roles

Direct experience of Owner's Engineer, Principal Designer and independent technical assurance appointments at both utility and community scale. This is delivery experience, not observation of it.

A wider bench

Where a project needs discipline-specific depth or sustained site presence, Erebus brings in associates and independent practitioners with directly relevant sector experience, coordinated under a single point of technical responsibility.

Sector standing

Active involvement in the professional institutions that set standards in the sector, including committee and branch roles within the Energy Institute.
