Founder-led analysis and independent challenge for developers, owners, investors, and advisory teams. OBRAVEN helps decide what to measure, what to trust and whether the energy yield basis is ready for the next project gate – onshore and offshore, in Ireland and international markets.
Founded by Stan Herasymenko. 17+ years across measurement delivery, technical advisory and developer-side leadership at Mainstream Renewable Power, DNV and ENERPARK, including leadership of Mainstream’s global Energy Analysis Group. Career experience includes 200+ measurement stations specified or overseen, 300+ resource and energy-yield assessments delivered or reviewed, and 1,000+ layout and turbine scenarios analysed or overseen. OBRAVEN brings that depth to defined assignments and ongoing senior support.
Energy analysis often starts long before the finance-stage EYA. Measurement, layout, turbine, wake, blockage, loss and uncertainty assumptions evolve through development. OBRAVEN helps teams keep that analytical basis controlled, proportionate and traceable – and challenge it before the number is priced or relied on.
Hidden risk
The current estimate may still reflect an earlier layout, turbine, measurement or loss basis that no longer matches the project.
How we help
We prepare or update the wind-resource and energy-yield analysis on an agreed basis, including wakes, blockage, losses, uncertainty, sensitivities and controlled outputs.
Hidden risk
Measurement campaigns can be over-scoped, under-designed, or badly sequenced – leaving clients with either wasted spend or data that will not stand up when bankability matters.
How we help
We design onshore and offshore measurement strategy from the decision backward – sizing scope, sequencing, procurement, and supplier obligations to what the project actually needs to prove at investment and finance stage.
Hidden risk
A campaign can look compliant on paper yet still fail through weak supplier obligations, QA, maintenance, monitoring, or escalation.
How we help
We help teams set up and govern measurement programmes so that RFPs, contracts, supplier scope, maintenance expectations, review rhythms, and escalation paths are aligned to one objective – a robust finance-grade evidence base at proportionate cost.
Hidden risk
Technical studies can all be completed and signed off, yet still fail to add up to a financeable, decision-ready project.
How we help
We connect outputs across energy yield, layout optimisation, turbine choice, noise, and related disciplines so the combined picture is judged against bankability, deliverability, and technical-commercial consequence – not just report-by-report completion.
Hidden risk
Projects often default to new measurement spend before anyone proves the decision really needs it.
How we help
We assess whether the right route is a full new campaign, a reduced scope, a different evidence base, or no new measurements at all – protecting decision quality without buying unnecessary work.
Hidden risk
Measurement, monitoring, layout, modelling, and energy assessment tools or services are often chosen through habit or legacy preference rather than fit for purpose.
How we help
We scope the real need first, then compare relevant tools or services on fitness for purpose, integration, downstream use, and commercial logic – rather than inertia or internal preference.
Bring one live project question. Share the project stage, the decision ahead, the analysis or data already available and any deadline. In a short call, OBRAVEN will confirm whether it is the right fit and the narrowest useful next step.
