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