5 Overlooked Details That Can Make or Break Battery Energy Storage Projects for Developers & Utilities
October 23, 2025
Battery energy storage projects are complex undertakings that require coordination across engineering, construction, procurement (EPC), financing, and operations. Yet even experienced developers and utilities can stumble over a few critical details that make or break a project’s success.
At TruGrid, we understand how small oversights can ripple into costly delays, so we work proactively to ensure these concerns are eliminated before execution. Below are five commonly overlooked issues and practical ways to tackle them with your EPC partner.
1. Mismatch Between Electrical Design and Interconnection Requirements
A mismatch between the system design and interconnection requirements is one of the most frequent and expensive issues developers face. If the utility’s interconnection specifications don’t align with the project’s electrical design, teams can face redesigns, resubmittals, and costly delays.
The Solution:
Engage your EPC early to confirm interconnection requirements with the utility.
Incorporate flexibility into designs to accommodate evolving grid standards.
Use detailed verification checklists to align drawings, one-lines, and protection schemes.
As TruGrid’s Chief Commercial Officer Chris Finley explains, “Successful contracting begins with precise alignment, both commercially and technically. When developers and EPCs contract with a clear scope and shared expectations, it sets the foundation for efficient execution.”
Interconnection delays have become a top challenge for developers across North America, so much so, that TruGrid has developed a white paper to successfully navigate interconnection and telemetry requirements. It provides an in-depth guide to overcoming the regulatory, technical, and operational challenges that frequently delay project commissioning or result in costly inefficiencies.
2. Poor Scheduling That Ignores Seasonal Weather
Seasonal weather conditions can significantly impact construction timelines and site readiness. Overlooking local climate patterns like heavy rains in the Gulf Coast or deep freezes in the Midwest often leads to lost productivity, schedule delays, and higher costs.
The Solution:
Incorporate historic weather data into scheduling and logistics plans.
Sequence work so that weather-sensitive tasks happen during more predictable months.
Build in contingency time and equipment for weather disruptions.
Planning for weather is a hallmark of seasoned EPCs like TruGrid, where schedule models are built around local climate data to ensure efficiency through every season.
3. Inadequate Thermal Management and HVAC Design
Thermal management is a critical component of battery system reliability. Poor heating, ventilation, and air conditioning (HVAC) design can shorten equipment life and increase safety risks, particularly in high-temperature regions.
The Solution:
Ensure thermal management designs are reviewed by both the integrator and EPC for redundancy.
Specify HVAC systems rated for the site’s environmental conditions.
Implement proactive commissioning and monitoring to verify performance under load.
A strong EPC partner should work closely with technology providers to integrate HVAC design seamlessly into the overall system, ensuring long-term safety and uptime.
4. Financing Issues and Contracting Gaps
Even technically sound projects can falter due to financing or contracting gaps. Incomplete or unclear contracts often lead to change orders, delayed funding releases, and project disputes.
The Solution:
Clarify cost responsibilities for interconnection upgrades, testing, and commissioning.
Align project cash flow with key construction milestones.
Establish transparent communication between the developer, EPC, and financiers.
As TruGrid COO Josh Richardson notes, “Contracting for critical scope details, like equipment delivery schedules, interconnection timing, and commissioning responsibilities, helps ensure a smooth, successful project delivery. When these are clear from the beginning, execution becomes far more predictable.”
5. Competing Labor Markets
The renewable energy sector is now competing with industries such as data centers for qualified electricians, project managers, and skilled trades. In areas like Texas and California, where both energy and data center infrastructure development are booming, this competition can strain project timelines and budgets.
The rising investment in data centers and other facilities has created intense demand for skilled labor, driving up construction costs across the energy sector.
The Solution:
Partner with an EPC that maintains consistent relationships with regional labor networks.
Develop early workforce plans to secure key trades before peak demand periods.
Support workforce development initiatives that strengthen long-term labor availability.
At TruGrid, early labor planning and regional partnerships help stabilize project schedules, even in competitive markets.
The Bottom Line
Battery energy storage projects succeed when the technical, commercial, and logistical pieces fit together seamlessly. Avoiding the pitfalls of design mismatches, weather delays, thermal risks, financing gaps, and labor shortages starts with choosing the right partners and engaging them early.
By identifying these potential risks during preconstruction and contracting for them upfront, developers and utilities can ensure smoother execution, fewer surprises, and stronger returns over the life of their projects.
