The construction and renewable energy sectors are rapidly evolving, and Blattner Company, one of the most respected names in utility-scale energy construction, has just taken a significant step to reinforce safety and compliance across its contractor network.
Effective immediately, Blattner has partnered with ISNetworld® (ISN)—a globally recognized contractor management system—to streamline and strengthen its subcontractor prequalification process. This requirement applies to all subcontractors, suppliers, and vendors performing work on any Blattner job site.
If you’re currently contracted with Blattner or hoping to be, maintaining compliance in ISNetworld is no longer optional—it’s essential for doing business.
Who Is Blattner?
Blattner Company, a Quanta Services company, is a national leader in engineering, procurement, and construction (EPC) for large-scale renewable energy projects. Headquartered in Avon, Minnesota, Blattner has delivered hundreds of wind, solar, and energy storage installations across North America.
With a presence in key regions like California, Texas, Iowa, and the Midwest, Blattner works with top-tier developers and energy providers including NextEra Energy, Xcel Energy, and Invenergy. Contractors who maintain relationships with Blattner gain access to long-term projects and ongoing work—but only if they meet the company’s elevated standards for safety, documentation, and compliance.
What Blattner’s ISNetworld Rollout Means for You
Blattner recently issued a formal notice to its subcontractors: moving forward, all companies performing work on Blattner projects must be registered in ISNetworld. This change is part of a broader initiative to reduce incidents, align subcontractors with company-wide safety expectations, and streamline the vetting process.
Here’s what contractors need to know:
- If you already have an active ISNetworld account, you must connect your profile to Blattner and upload any additional documents specific to their requirements.
- If you are not yet a member of ISNetworld, you’ll need to complete the registration process, which includes submitting your safety programs, OSHA logs, training records, insurance certificates, and completing ISN’s HSE Questionnaire.
Failure to comply with these requirements can affect your ability to begin—or continue—work on Blattner sites.
Why Staying in Compliance with Blattner Matters
Blattner manages some of the largest and most complex renewable energy construction projects in North America. Getting qualified to work with them opens the door to competitive, high-value contracts and long-term business opportunities.
But failing to meet their ISNetworld expectations can result in:
- Delays in project access or approval
- Suspended work or missed bidding opportunities
- Negative performance grades in ISNetworld that affect your prequalification status with other clients as well
Blattner takes contractor compliance seriously—and so should you.
