Software Could Unlock 300 GW on US Grid

Hidden Capacity Could Add 300 GW to the U.S. Grid

Software‑driven grid‑scanning can free up about 300 GW of transmission capacity on existing U.S. lines within three to five years, without building a single new power plant, according to GridCARE founder Amit Narayan on the Energy Empire podcast. The figure comes from a shift away from the ultra‑conservative “N‑2” planning model that treats every possible double‑failure scenario as likely, leaving most of the network idle.

How the Software Finds Unused Space

GridCARE runs quadrillions of power‑flow scenarios in minutes, pinpointing the rare hours when the grid would actually be constrained. By matching those windows with flexible resources—batteries, demand‑response, or interruptible tariffs—the tool shows utilities exactly when and where they can squeeze new generation through the wires. Duke University research led by Tyler Norris backs the claim: if large loads accept curtailment for just 0.25 % of the year (roughly two hours at peak stress), the current system could accommodate nearly 100 GW of additional demand.

Real‑World Wins: NY, Oregon, PJM

• National Grid (New York): GridCARE identified more than 650 MW of hidden capacity, instantly opening the door for new projects.
• Portland General Electric (Oregon): The software unlocked over 400 MW in Hillsboro, letting six data‑center developers connect years ahead of schedule.
• PJM Interconnection: An AI‑based review of 811 generation applications—representing 220 GW of capacity—was completed in under an hour, a task that normally takes weeks.

These pilots prove the concept works at utility scale and can shave months off interconnection queues that often stall multi‑million‑dollar solar and storage projects.

Why This Matters for Solar and Storage Developers

Utility‑scale solar farms and battery storage need a firm transmission path to market. Traditional planning forces developers into multi‑year queues and costly network upgrades, sometimes killing projects before they break ground. By surfacing “latent” capacity, GridCARE gives developers a near‑term lifeline: they can secure interconnection slots now, pair with flexible tariffs, and defer or avoid expensive new substations. Using existing wires more efficiently can help lower overall system costs, which can translate into lower electricity bills for end‑users.

What It Means for Israel

If the U.S. can unlock 300 GW, that equates to 30 million typical 10 kW home systems (300 GW ÷ 10 kW). In Israel, a 10 kW rooftop system in the central region yields about 17 MWh per year, worth roughly ₪8,160 at the residential tariff of ₪0.48/kWh. With a typical install cost of ₪3,150/kW, the payback period is just under 4 years. Multiply that by even a fraction of the 30 million potential U.S. systems, and the economic case for aggressive rooftop deployment becomes clear for Israeli households and investors alike. Moreover, software‑driven approaches could potentially help Israel’s grid operator NOGA identify hidden capacity and address interconnection challenges, supporting the nation’s 30 % renewable electricity target for 2030.
