01 The engineering problem

Every new load asks the network one question.

Can it carry this? Data centres, electrolysers and electrified industry arrive in tens to hundreds of megawatts. Answering that question well, and proving the answer, is an engineering problem before it is a commercial one.

CAPACITY

How much can this point carry?

Hosting capacity at a connection point, at every stage of a site's growth, with the first binding limit named: a line, a transformer or a voltage.

CONTINGENCY

What if a line is lost?

A connection that works with every circuit in service has to hold through each credible outage, for every stage and every option.

EVIDENCE

What actually happened?

Once a site runs, its study assumptions drift. Network and customer need a shared record of events that either side can check.

02 Flagship capability

GridWindow

One engine that follows a connection through its whole life, from the first study to the last event. Every figure comes from a full AC power-flow calculation and is confirmed by an independent solver.

OwnershipGridWindow is developed and owned by Cloudsail Technologies. SEHRO proposes to commercialise it; the IP arrangement has not yet been completed.
BEFORE

Connection and capacity

AC power flow at every growth stage, intact and under each listed outage. Hosting capacity with every figure classified by how far it can be trusted.

DURING

Assumption monitoring

Measured site and network data tested against the assumptions the connection was studied on, with drift surfaced and its evidence attached.

AFTER

Verifiable reconstruction

Event time and knowledge time kept apart, written to a signed evidence pack that a third party can verify and re-run.

Technical overview

03 Technical direction

Engineered for network scale.

Screening one connection takes thousands of AC solves across stages, outages, options and operating snapshots. On transmission networks with thousands of buses, that becomes an accelerated-computing problem.

D.01

GPU-batched power flow

Thousands of stage and contingency cases solved in parallel, with sparse linear solves batched on GPUs using NVIDIA cuDSS.Proposed · First: profile a multi-thousand-bus network

D.02

Grid digital twin

Screened scenarios exported as OpenUSD scenes for NVIDIA Omniverse, so a connection can be studied in its real geography.Proposed · First: a licensed geographic dataset

D.03

Plain-language scenarios

An engineer describes a connection in words; a model served as an NVIDIA NIM drafts a validated scenario for the engineer to confirm before any calculation.Proposed · First: an agreed accuracy test set
