Part 107 UAS pilot reported they were flying the UAS back to its landing location when it struck a set of power lines. The UAS remained in the power lines and the power company was notified.

Narrative

We were flying a commercial real estate photo job and during ascent to return to home overhead power lines were impacted and drone was tangled in power lines. No power issues were apparent; and the utility company was contacted immediately. Utility company has confirmed the situation on-site and will retrieve UAS when a bucket truck is available.Remote Pilot In Command (RPIC) and Visual Observer (VO) were not communicating at the highest level possible; and RPIC did not accurately estimate the location of the power lines when ascending. Additionally; flight crew did not continue awareness after initial site survey and accurately assess overhead hazards. Complacency was the main contributing factor to this incident; and RPIC and VO have worked together for significant flight hours and felt comfortable with past results.RPIC was not located close enough to the VO to receive information in a timely manner and missed the VO's verbal warning due to background noise in the area. VO exhibited signs of distraction and complacency as well; and both parties should have worked together to keep awareness and communication at a higher level.
