Sharper judgement where wind resource evidence meets bankability.

OBRAVEN helps developers, investors, and advisory partners make better decisions about wind resource measurement, energy yield assumptions, and whether the evidence behind the revenue case will stand up when bankability matters.

Founder

Founded by Stan Herasymenko. 17+ years in wind energy across DNV and Mainstream Renewable Power, spanning wind resource measurement strategy, energy analysis, and technical-commercial advisory. At Mainstream, Stan led the Energy Analysis Group across a multi-GW wind and solar portfolio. His direct measurement experience covers 110+ met masts across 30+ countries, including floating LiDAR campaign work.

Core capabilities

Wind resource measurement strategy and procurement support – onshore and offshore, including floating LiDAR
Independent challenge of energy yield assumptions, resource assessment outputs, consultant reports, and bankability logic
Technical-commercial review at decision gates – connecting resource evidence, layout, turbine choice, and financing readiness
Specialist subcontract support to advisory firms and diligence teams on defined wind resource, energy yield, and bankability workstreams

Engagement model

Defined-scope project work on wind resource measurement strategy, campaign design, energy yield assumption review, or bankability challenge
Independent owner-side or investor-side review of third-party resource assessment, energy yield, and related technical outputs
Subcontract or collaboration alongside advisory firms, developers, and diligence teams – senior engagement, not delegated

Typical decision situations

The risk often isn't in a single report or workstream – it's in the gap between them. Where resource measurement campaign design doesn't quite match the bankability case. Where assumptions survive unchallenged because no one owns the join between disciplines. These are the places where experienced independent review changes the outcome.

Offshore resource measurement strategy

Hidden risk

Offshore wind resource 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 define offshore measurement strategy from the decision backward – including floating LiDAR scope, sequencing, campaign design, and procurement support – so the campaign is proportionate, commercially sensible, and robust enough for a finance-grade outcome.

Bankable dataset quality

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 dataset at proportionate cost.

Do we need a measurement campaign at all?

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.

Are the energy yield and uncertainty numbers decision-fit?

Hidden risk

Seller and consultant cases can look plausible while still carrying optimism that is too aggressive for the decision at hand.

How we help

We test whether energy yield assumptions, losses, uncertainty estimates, and technical conclusions are proportionate, defensible, and aligned with the real investment or acquisition decision – including helping clients true up aggressive cases before they become expensive mistakes.

Do the resource, layout, and yield workstreams add up?

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, noise, turbine choice, and related disciplines so the combined picture is judged against bankability, deliverability, and technical-commercial consequence – not just report-by-report completion.

What should we procure or rely on?

Hidden risk

Measurement, monitoring, plant design, 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.
