A sponsored Utility Dive report says utilities can address some near-term electricity pressures by improving how they operate existing grid assets while continuing to build new infrastructure. It cites a Southwest Power Pool planning-time reduction and recent congestion-management efforts, but the scale and timing of savings from wider adoption remain uncertain.
A sponsored Utility Dive report argues that North American utilities should look beyond new transmission construction and make better use of capacity in existing grid assets as electricity demand rises. The proposal is not a substitute for building and modernizing infrastructure, the report says, but a way to improve near-term grid performance while larger projects take time to plan and complete.
The report points to several sources of pressure on the power system, including data centers, industrial electrification, electric vehicles, manufacturing growth and population increases. It cites a North American Electric Reliability Corp. projection that U.S. electricity consumption could increase from 4,281 terawatt-hours in 2024 to 5,353 TWh in 2034. That is a forecast, not a measurement of demand already realized, and the report notes that other studies project higher growth.
It argues that operators may be able to use current infrastructure more effectively because transmission equipment is sometimes run using conservative assumptions, constraints in one part of a network can obscure capacity elsewhere, and fragmented data can limit visibility. Proposed tools include asset monitoring and integrated data systems, as well as dynamic line ratings and advanced power-flow controls to help operators manage conditions on existing transmission corridors.
As examples, the report says Southwest Power Pool reduced transmission planning time by 30% after modernizing its planning processes and adopting advanced analytics. It also says the Federal Energy Regulatory Commission approved SPP’s topology-optimization plan in August 2026 and cites reported congestion-cost savings of about $95 million for MISO from similar efforts earlier in the year. The source does not provide enough detail here to independently assess the methods, periods covered or broader applicability of those figures.
Using Existing Lines While Demand Grows
Grid construction can take years, while utilities are already handling new requests from data centers and other large electricity users. If operators can safely identify spare capacity or reduce constraints on the network, optimization could offer some near-term flexibility before new lines and substations are ready. That could help utilities plan connections, maintenance and targeted upgrades with better information.
The report cites analysis estimating that improved use of the U.S. power system could produce more than $100 billion in savings over the next decade. This is an estimate from referenced analysis, not a guaranteed saving or a result already achieved across the grid. Actual outcomes would depend on where capacity exists, operating limits, technology costs and whether system changes can be implemented without compromising reliability.
The central policy and planning point is a dual-track approach: optimize current assets and continue expanding the network. Treating the options as alternatives could leave utilities without either the immediate operational improvements or the long-term capacity needed to serve sustained demand growth.

Demand Forecasts and Grid Backlogs
The source describes a mismatch between the speed of new electricity demand and the time required to connect generation and construct network infrastructure. It cites Berkeley Lab data showing that more than 2 terawatts of U.S. generation and storage capacity was in interconnection queues by mid-2026. Queue capacity represents proposed projects awaiting connection processes; it is not the same as operating power plants or a confirmed amount of capacity that will be built.
The report also says the Electric Reliability Council of Texas received nearly 200 gigawatts of large-load applications in the first quarter of 2026. Applications indicate interest and requests, not necessarily projects that will proceed or become actual electricity use. The figures illustrate the scale of planning pressure described by the report, but they should not be read as delivered supply or demand.
Grid optimization is presented as one response alongside new investment. The report promotes a Hitachi Energy white paper on the subject and is explicitly sponsored content. Its examples and estimates should be understood as claims in that report, rather than as a comprehensive independent evaluation of all utilities’ performance.

Savings and Capacity Still Need Proof
The report does not specify how much additional usable capacity could be unlocked across North America, which regions could benefit most, or how quickly utilities could apply the approaches at scale. It also does not provide a common measurement method for comparing the cited planning-time and congestion-cost results with outcomes elsewhere.
The $100 billion savings estimate is attributed to outside analysis, but the supplied material does not explain its assumptions, cost categories or sensitivity to future demand and investment. Likewise, queue totals and large-load applications can change as projects are revised, delayed or withdrawn. They do not establish how much new generation or demand will ultimately materialize.
Operators must also account for equipment limits, reliability requirements and local grid conditions. The report advocates using existing infrastructure more effectively, but does not claim that every constrained system has spare capacity or that digital tools can remove every bottleneck. The extent of the opportunity remains specific to each network and requires assessment by grid operators.

Utilities Must Pair Tools With Buildout
The practical next step is for utilities and grid operators to identify where better monitoring, updated planning methods or grid-enhancing technologies can safely improve performance, and to measure results against clear operating and cost baselines. The examples cited by the report may encourage further evaluation, but they do not establish a uniform outcome for other systems.
Meanwhile, utilities and regulators will continue to face decisions about transmission investment, project connections and the pace of electricity-demand growth. The report’s argument is that optimization should proceed alongside construction, with each region determining what its existing assets can support and what new infrastructure remains necessary. The scale of actual capacity gains and consumer savings will become clearer only as projects are implemented and independently evaluated.

Key Questions
What does “hidden capacity” mean in the report?
It refers to potential to use existing grid infrastructure more effectively, through improved system visibility, planning and operational tools. It does not mean every network has unused capacity available without limits.
Does grid optimization replace new transmission construction?
No. The report says utilities need to keep expanding and modernizing transmission and distribution systems. Optimization is presented as a complement to investment, not a replacement.
Are the reported savings guaranteed?
No. The report cites an analysis estimating more than $100 billion in potential U.S. savings over a decade. That is an estimate, and the supplied source material does not detail its assumptions or establish that the savings have been achieved.
Do interconnection queue figures represent power that is ready to use?
No. Queue totals describe proposed generation and storage projects awaiting connection processes. They are not operating capacity, and some projects may change, be delayed or not proceed.
