Point-of-interconnection engineering is where developer schedules meet utility requirements. American Power Engineers supports developers, IPPs, and EPCs through interconnection studies, POI design, and utility coordination.
We support developers and EPCs through every stage of point-of-interconnection engineering, from facility studies and SIS reviews to POI single-line design and utility coordination.
Interconnection queues, evolving utility requirements, and grid impact concerns create real schedule and cost risk for developers connecting to the bulk power system.
Familiarity with utility and ISO interconnection workflows.
Independent review of utility study results and POI scope.
Electrical, protection, and communications coordinated together.
Technical representation in utility coordination meetings.
Engineering aligned to interconnection milestones.
Share a few details and our team will follow up to scope your power system studies engagement. Qualified inquiries only — we respond to developers, utilities, EPCs, and industrial owners.
Tools and platforms used on a given project depend on scope, utility requirements, and client preference.
