Industry brief · Power & digital

Transmission & distributionHV/EHV lines, substations, HVDC, distribution & smart metering

The grid build-out that gates every other power and digital asset: EHV AC lines and substations, HVDC corridors (Khavda, Ladakh, SunZia, SuedLink, North Sea), distribution modernisation and AMI smart meters. Global grid spend is ~USD 400bn/yr vs ~USD 1tn on generation; 1,650 GW of advanced wind/solar projects were waiting for grid connection in 2024. Capital risk is dominated by transformer/cable/HVDC-converter scarcity (lead times ~2-5 years, prices up ~75-100% since 2019-21), right-of-way and permitting, interconnection-queue backlogs and regulated-return politics.

How Capibud uses this pack

A pack is a starting position, not a forecast. When a transmission & distribution decision opens in Capibud, pack v1.0.0 is copied in and pinned to that decision. The 13 parameters, 10 swing factors and templates the committee saw stay attached to the decision record, even after the pack is next refreshed.

Parameter ranges and WBS durations seed the P50, P80 and P90 for capex, schedule and value. Your own estimates, vendor quotes and actuals replace pack defaults line by line, and the record shows which numbers are still defaults.

Each swing factor is wired to shared factors; here the heaviest are policy, electrical equipment, grid queue and labour. A move in one factor hits every exposed project in the same scenario, which is how the capital committee sees concentration across a book rather than project by project.

The 14 price feeds and 34 listed tickers feed the brain, which watches for drivers moving outside their pack range and drafts the change for a person to review.
