Why 765 kV - and Why Now
The global energy system is entering a period of radical transformation. Driven by the explosive growth of AI data centers, renewable energy integration at continental scale, mass EV adoption, and accelerating industrial electrification, the demand for power transmission capacity is growing faster than the existing grid can accommodate.
765 kV is the answer. Operating at ultra-high voltage reduces transmission losses significantly, moves far more power on fewer lines, and is the only technology appropriately scaled for the grid of 2030 and beyond. The infrastructure built over the next decade will define energy security and industrial competitiveness for a generation.
“Most utilities deploying 765 kV will be doing so for the first time – facing unfamiliar technical complexity, multi-vendor coordination risk, and the pressure of timelines that leave no room for integration failures discovered after energization.”
Daniele Buscemi
Vice President Business Development and Technical Sales, Trench Group
The question is not whether to invest in 765 kV infrastructure. That decision is already being made by regulators, grid operators, and utilities worldwide. The question is who to trust as your technical reference – the partner with the depth of knowledge, breadth of portfolio, and continuity of commitment to guide you from specification to commissioning and beyond.
01
Hyperscale facilities are driving demand for dedicated 765 kV grid connections. Single large campuses can draw over 1 GW continuously – a load that exceeds the transmission capacity of conventional 345 kV infrastructure.
02
Wind and solar resources are hundreds of miles away from load centers. 765 kV corridors are the only cost-effective path to moving clean power at a continental scale, with minimal transmission losses.

The Essentials of 765 kV
A practical guide to understanding the technology driving the next generation of grid infrastructure.
LESS IS MORE
345kV six single circuit towers
MORE IS MORE
Electricity travels more efficiently at higher voltages. Doubling the voltage substantially increases the power you can transmit on the same lines.
At lower voltages, energy losses over hundreds of miles become substantial. 765 kV lines significantly reduce energy losses over long-distance transmission – making it the practical choice for connecting remote renewable sources to cities and industrial zones far away.
One 765 kV tower does the work of six conventional 345 kV towers. Far less land use, fewer towers to build and maintain, and a significantly lower environmental footprint – while delivering more capacity to where it’s needed most.
Higher voltage requires every product – bushings, instrument transformers, coils – to be engineered specifically for 765 kV conditions. Standard equipment from lower-voltage networks cannot be reused. This is why specialist manufacturers matter.

What Is Driving This Build-Out
AI & Hyperscale Data Centers
Campus-scale AI computing facilities requiring 1–3 GW of continuous power are being sited across the U.S., demanding transmission capacity that existing 345 kV infrastructure cannot deliver.
Industrial Re-Electrification
EV battery plants, semiconductor fabs, and green steel mills are creating new major load centers - often in regions with limited high-voltage infrastructure - driving urgent grid upgrade cycles.
Long-Haul Renewable Transmission
Connecting wind and solar in the Midwest and West to coastal population centers requires new 765 kV long-distance corridors. Lower voltages are not economically viable at these distances.
Policy Tailwinds & Buy America
Federal infrastructure legislation and energy security mandates provide both funding and regulatory momentum. Buy America provisions specifically reward utilities sourcing components from U.S.-based manufacturing.
- FOR INVESTORS & DEVELOPERS
Approaching this Opportunity with the Right Preparation
The U.S. 765 kV build-out represents a generational opportunity – but one that demands serious preparation.
The technical complexity of ultra-high voltage is real, and most utilities entering this space are doing so for the first time.
Equipment lead times are long, supply chains are constrained, and integration failures discovered late are extraordinarily costly.
Projects that get these answers right early move faster, commission cleanly, and carry significantly lower technical risk.
Those that don’t, discover the gaps at the worst possible moment: during energization.
Key questions for any investor or developer evaluating a 765 kV project
- Does the utility have an experienced technical partner covering the full product portfolio?
- Is there a confirmed domestic supply chain that satisfies Buy America requirements for federal funding eligibility?
- Are lead times for bushings, instrument transformers, and coils already factored into the project timeline?
- Has a system integration study been commissioned - not just individual component specifications?

- EXPERT INSIGHT
What Most People Get Wrong About 765 kV
Why technical complexity is the hidden variable in every project plan
The conversation about 765 kV in North America is dominated by numbers: miles of new lines, billions in investment, substations planned. These numbers are real and significant. But they obscure the harder conversation – which is about what it actually takes to deploy 765 kV infrastructure successfully, and how many organizations underestimate that challenge at the specification stage.
The difficulty is not the voltage itself. The difficulty is that 765 kV forces every component – and every system interface between components – to perform at margins that leave no room for the kind of minor misspecifications and inter-vendor gaps that can be tolerated at 345 kV.
At ultra-high voltage, those margins do not exist. Small errors propagate.
What goes wrong is coordination.
When a bushing from one manufacturer, a current transformer from a second manufacturer, and a reactor from a third are brought together at a 765 kV bus, it is important to ensure that a technical lead takes ownership of system-level integration across components from different manufacturers – at a circuit level, a thermal level, and a protection relay setting level. The components may individually pass their type tests while still creating real, expensive problems in service.
Questions worth asking before you issue tender documents
- Who owns technical accountability when components from different vendors interact unexpectedly at commissioning?
- Has your protection engineer reviewed CT/VT accuracy class combinations across all measurement points for your relay coordination strategy?
- Has the impact of your reactor choice on transformer neutral grounding been modeled for single-phase switching transients?
- Do your specifications include integrated type testing requirements, or only individual component tests?
- Is your team - or anyone on your team - experienced with 765 kV commissioning? If not, who is your technical reference?
None of these questions require you to buy from a single supplier. But they do call for one technical reference – an organization with comprehensive knowledge of the 765 kV challenge who can answer these questions authoritatively, across product families, and give you an honest, complete picture of the complexity at stake.
That is what Trench Group offers.
We are not asking you to take everything at once or together. Products, consulting, and asset services are each available individually or in combination. We are offering the expertise, the track record, and the portfolio breadth to be your trusted source of truth.
