The American energy transition is currently facing a physical bottleneck. While the deployment of wind and solar arrays has accelerated across the Great Plains and the Southwest, the infrastructure required to move that power to the cities that need it has lagged decades behind. This “interconnection gap” has left gigawatts of clean energy stranded, unable to reach the grid due to a fragmented regulatory landscape and a lack of high-voltage transmission lines.
Michael Skelly has spent the better part of two decades attempting to solve this specific problem. As the founder and CEO of Grid United, Skelly is now leading an early-stage transmission development company designed to bypass the traditional, often sluggish, utility-led approach to grid expansion. His goal is to build the “highways” of the energy transition, ensuring that the decarbonization of the U.S. Economy is not stalled by a lack of wires.
Skelly’s current venture is the culmination of a career spent at the intersection of infrastructure, finance, and environmental policy. From scaling wind energy startups to navigating the labyrinthine permitting processes of federal and state agencies, his trajectory reflects the evolving challenges of the U.S. Renewable energy sector. His approach combines the agility of private equity with a deep understanding of the public-sector hurdles that typically derail large-scale infrastructure projects.
Beyond the energy grid, Skelly has applied this same infrastructure-centric philosophy to urban planning in Houston, Texas. By treating city parks and transit options as critical infrastructure rather than mere amenities, he has helped reshape the physical landscape of his adopted hometown, bridging the gap between industrial efficiency and civic livability.
The Grid United Strategy: Solving the Interconnection Crisis
The primary obstacle to a carbon-free grid is not the generation of power, but the transmission of it. In the current U.S. Model, most transmission is planned and built by regulated utilities, a process that can take a decade or more due to “cost allocation” disputes—arguments over which states or ratepayers should pay for a line that crosses multiple borders.
Grid United operates with a different premise. By focusing on strategic transmission development, the company seeks to identify the most critical gaps in the network and develop projects that can be brought online more efficiently. This involves navigating the complex “interconnection queue,” where renewable projects often wait years for a study to determine if the grid can handle their load.
Skelly’s expertise in this area was forged during his tenure as founder and president of Clean Line Energy. Clean Line was an ambitious attempt to build some of the longest transmission lines in the U.S. In recent history, aiming to bring wind power from the Midwest to the East Coast. While Clean Line successfully permitted significant portions of its projects, it also served as a masterclass in the regulatory friction inherent in U.S. Energy policy. The lessons learned there—specifically regarding the volatility of state-level approvals—now inform the leaner, more targeted strategy at Grid United.
A Professional Evolution in Renewables
Before pivoting to transmission, Skelly focused on the generation side of the equation. He led the growth of Horizon Wind Energy, a firm that became a major player in the early expansion of U.S. Wind power. Horizon was eventually integrated into EDPR (Energias do Portugal), one of the largest renewable energy companies in the United States.
This progression—from generating power at Horizon to moving power at Clean Line, and now optimizing the system at Grid United—represents a holistic view of the energy value chain. Skelly’s academic background provides the framework for this approach; he holds a bachelor’s degree in economics from the University of Notre Dame and an MBA from Harvard Business School, blending economic theory with the practicalities of project finance.
| Organization | Primary Focus | Key Contribution/Outcome |
|---|---|---|
| Horizon Wind Energy | Renewable Generation | Scaled wind operations; later acquired by EDPR. |
| Clean Line Energy | Long-haul Transmission | Permitted some of the longest U.S. Lines in 50 years. |
| Grid United | Transmission Development | Current CEO; focusing on early-stage grid optimization. |
Infrastructure as a Civic Tool in Houston
Skelly’s commitment to infrastructure extends beyond the energy sector. In Houston, he has focused on the “last mile” of urban mobility and public health. He recognizes that the same principles used to permit a transmission line—stakeholder alignment, funding procurement, and long-term planning—can be applied to urban green spaces.
In 2012, Skelly spearheaded the “Parks By You” campaign. The initiative was not merely a beautification project but a strategic infrastructure push. The campaign successfully led to the passage of a $150 million bond measure, which funded the creation of over 100 miles of trails along the city’s bayous. This effort transformed the bayous from neglected drainage corridors into a connected network of recreational arteries for the city’s residents.
His influence in Houston is further cemented through various board positions where he advocates for multimodal transportation and sustainable innovation. These include:
- Houston Bike Share & LINK Houston: Working to reduce car dependency in one of the most sprawled cities in the U.S.
- Houston Parks Board: Continuing the expansion of accessible green space.
- Greentown Labs Houston: Supporting the “climatetech” ecosystem by providing space and resources for hardware startups.
The Synergy of Storage and Transmission
One of the most critical components of Skelly’s current ecosystem is his role on the board of Form Energy. While Grid United focuses on the movement of energy, Form Energy focuses on the storage of it. Form Energy is developing iron-air battery technology designed for long-duration energy storage (LDES), which can hold charges for days rather than hours.
From a systems perspective, transmission and storage are two sides of the same coin. Transmission allows energy to move across space (from a windy plain to a city), while storage allows energy to move across time (from a sunny afternoon to a dark winter night). By engaging with both, Skelly is positioning himself at the center of the “firming” of renewable energy—turning intermittent sources like wind and solar into reliable, baseload power.

As the U.S. Government continues to release funding via the Infrastructure Investment and Jobs Act and the Inflation Reduction Act, the pressure to accelerate transmission builds. The next critical checkpoint for the industry will be the implementation of new FERC (Federal Energy Regulatory Commission) rules aimed at streamlining the interconnection process, a development that will directly impact the operational runway for firms like Grid United.
