What Watt Coalition does

WATT Coalition (Working for Advanced Transmission Technologies), founded in 2017 and headquartered in Washington D.C., is a non-profit policy advocacy coalition that promotes deployment of Grid Enhancing Technologies (GETs) on the U.S. electric transmission grid. Its three advocacy pillars are Dynamic Line Ratings (DLR), which use sensors and algorithms to calculate real-time transmission line capacity based on ambient conditions; Advanced Power Flow Control, which uses modular devices to actively redistribute power between circuits; and Topology Optimization software, which identifies optimal grid reconfigurations to redirect flows around congestion. The coalition does not sell products or services; its primary outputs are policy advocacy, commissioned research, regulatory comment filings, and member-supported direct engagement with federal and state policymakers.

WATT Coalition is governed and funded by 13 member companies spanning technology vendors (Ampacimon, LineVision, Smart Wires, Heimdall Power, NewGrid, Prisma Photonics), utilities and developers (VELCO, EDF Power Solutions, Invenergy, ENGIE, Sol Systems), and investors (HASI). Its primary 'customers' are federal and state policymakers (U.S. Congress, FERC, DOE, NARUC, state public utility commissions) and the investor-owned utilities, cooperative utilities, and ISOs/RTOs that operate the grid. The coalition engages policymakers through testimony, comment filings, an annual DC Fly-In, 35+ annual conference appearances, and joint advocacy with allied coalitions (AMP Coalition, ACORE, GridLab).

Its business model is membership dues plus commissioned research dissemination; no commercial pricing exists. The coalition has materially shaped U.S. transmission policy — most notably FERC Order 1920 and 1920-A (2024), which require transmission providers to study and deploy GETs where cost-effective — and has driven GETs legislation in 12 states in 2025 alone, with 18 states total introducing relevant bills. Quantified outcomes attributed to GETs include 40%+ congestion cost reduction, 100+ GW of potential capacity unlock, and $5 billion in annual energy cost savings (Brattle Group).

Core offering

WATT Coalition is a non-profit advocacy coalition that promotes the deployment of Grid Enhancing Technologies (GETs) — Dynamic Line Ratings, Advanced Power Flow Control, and Topology Optimization — to unlock transmission grid capacity, reduce congestion, and integrate renewable energy. The coalition convenes technology vendors, utilities, clean energy developers, and investors to conduct research, file comments at FERC and state commissions, support legislation, and educate policymakers on the value of GETs as a faster, lower-cost alternative to traditional transmission build-out.

Product overview

Watt Coalition (WATT Coalition) is an advocacy organization that promotes Grid Enhancing Technologies (GETs) for modernizing the electric transmission grid. The coalition advocates for three core technologies: Dynamic Line Ratings (DLR), Advanced Power Flow Control, and Topology Optimization software. These technologies work together to unlock the grid's untapped potential to deliver reliable, affordable, and clean power—faster, smarter, and at lower costs than traditional infrastructure alone. DLR measures real-time line capacity, Advanced Power Flow Control actively balances power distribution across transmission lines, and Topology Optimization identifies optimal grid reconfigurations to reroute power flow around congested areas.

Products and services

• Dynamic Line Ratings (DLR) DLR monitors ambient conditions (wind speed, temperature, solar radiation, precipitation) that heat or cool transmission lines to calculate the true real-time capacity of lines based on their thermal limits. Unlike static ratings, DLR uses sensors and algorithms to measure actual line capacity, typically unlocking 10–30% more capacity 90% of the time. WATT Coalition promotes DLR adoption as a technology category to policymakers and grid operators.
• Advanced Power Flow Control Advanced Power Flow Control technologies actively shift or redistribute the flow of electricity between available transmission circuits, pushing power away from overloaded lines onto underutilized corridors. Examples include modular, scalable, and redeployable devices such as SmartValve and M-SSSC that can be installed quickly on existing infrastructure. WATT Coalition promotes this category to policymakers and grid operators.
• Topology Optimization Topology Optimization software identifies reconfigurations of transmission assets (opening/closing circuit breakers at substations) to redirect power flows around congested or overloaded transmission elements, improving transfer capacity. It acts as a 'Waze' for grid operators, automatically identifying optimal grid configurations in real-time. WATT Coalition promotes this software category to policymakers and grid operators.

Direct peers

• AMP Coalition: An ad hoc coalition of CTC Global, TS Conductor, VEIR, and MetOx advocating for High Performance Conductors on the US transmission grid. AMP Coalition is the closest peer to WATT Coalition — same coalition advocacy model, same federal/state policy targets, and frequent co-filing of FERC/DOE comments.
• Clean Energy States Alliance (CESA): A nonprofit coalition of state clean energy agencies and partners that drives state-level clean energy policy and program design. CESA operates a parallel state-focused coalition model to WATT Coalition and engages similar state legislators and utility regulators.
• GridLab: A clean energy policy and analysis organization that co-funded the Brattle Group's 'Unlocking the Queue' study with WATT Coalition. GridLab runs a similar non-profit advocacy model focused on grid modernization research and presents alongside WATT at White House Summits.

Others

• Grid Strategies LLC: A boutique energy policy research and consulting firm closely aligned with WATT Coalition leadership — both the Executive Director and State Implementation Lead are ex-Grid Strategies. Grid Strategies produces congestion cost analyses and FERC filings that underpin the coalition's data-driven advocacy.
• The Brattle Group: A global economic and litigation consultancy that produced the cornerstone 'Unlocking the Queue' and 'Building a Better Grid' studies commissioned by WATT Coalition. Brattle is an enabling research partner rather than a competitor, supplying the quantitative evidence base for the coalition's advocacy.

Broad incumbents

• Advanced Energy Economy (AEE): A national business association advocating for the entire advanced energy sector — covering transmission, distributed energy, storage, and demand-side technologies. AEE is broader than WATT Coalition but operates in the same federal/state energy policy advocacy lane and is a comparable incumbent voice.
• Natural Resources Defense Council (NRDC): One of the largest US environmental advocacy organizations with a substantial energy and grid modernization program. NRDC operates as a broad environmental incumbent that overlaps with WATT Coalition's clean energy transmission advocacy at the federal level.
• Energy Foundation: A major philanthropic organization that funds clean energy policy advocacy across multiple US states and regions. Energy Foundation operates as a broad clean-energy funder whose grantees frequently overlap with WATT Coalition's network of state-level clean energy advocates.
• American Council on Renewable Energy (ACORE): A national trade association representing renewable energy developers, financiers, and advocates. ACORE co-hosts Grid Forums with WATT Coalition and has submitted joint FERC comments on DLR rulemaking, making it a directly collaborating broader clean energy incumbent.

Emerging players

• Citizens for Responsible Energy Solutions (CRES): A 501(c)(4) conservative-aligned nonprofit advocating for clean energy and climate solutions. CRES brings a distinct ideological base that complements WATT Coalition's bipartisan approach and engages Republican policymakers on grid modernization.
