With growing energy demand across Texas, especially from data centers and large industrial facilities, developers increasingly require precise clarity into the power capacity that can be reliably imported at a given Point of Interconnection (POI). At EPE, we deliver the technical expertise necessary to evaluate and determine reliable power import capabilities, enabling clients to make informed decisions early in their project development process.
EPE’s Large Load Full Transmission Analysis allows developers to evaluate grid feasibility at any location within the ERCOT footprint, before committing capital or initiating the formal interconnection process. Whether you are exploring a new data center hub or assessing multiple potential POIs, this study is your first critical checkpoint.
What Benefits Can the Study Provide?
Using the most recent ERCOT base cases, EPE prepares a forward-looking model of the grid, including nearby generation and transmission upgrades expected to be in service when your project goes online. Our team then runs a full power flow analysis to determine the available import capacity at your selected POI(s), examining:
- N-0 base system (no contingencies)
- ERCOT single contingency (N-1) conditions
- Relevant multiple contingencies (N-1-1) as defined by NERC and ERCOT planning protocols
The result is a clear view of how many MWs your proposed large load could draw from the grid under various operating scenarios, and whether any thermal limitations may curb that capacity. The study can also be tailored to include sensitivity scenarios specific to your configuration, helping you make informed decisions about site selection and project size.
Why Does It Matter Now?
In today’s development climate, speed to market is essential, but so is predictability. By using EPE’s Large Load Transmission Analysis, developers can:
- Validate site feasibility early, without waiting on the lengthy LLIS/FIS process
- Compare multiple POIs to find the optimal balance of cost, reliability, and scalability
- De-risk permitting and engineering timelines by avoiding constrained or congested (high-demand) areas
This is especially important for data center projects, which often face tight construction windows and require reliable multi-MW interconnections. EPE’s analysis allows you to move faster with instrumental information and better visibility for both developers and investors.
Looking Ahead
ERCOT’s grid is becoming more dynamic, and site decisions are more strategic than ever. EPE is here to help developers, investors, and energy operators make informed interconnection decisions, backed by detailed analysis and deep modeling expertise.
In addition to our transmission analysis services, EPE supports developers in preparing and submitting load interconnection applications, including PSS®E and PSCAD dynamic models. Our services ensure compliance with ERCOT’s latest modeling standards and help minimize delays in the study process.
For more on ERCOT’s evolving large load interconnection process, refer to our May article covering the latest changes outlined in NPRR1234 and PGRR115, which were approved by the PUCT on May 15, 2025.
If you are evaluating POIs for a future data center or large load project, let us show you how EPE’s Full Transmission Analysis can bring you one step closer to the grid, effectively and competitively. Schedule a consultation with our expert team using the form below.
