Development to Delivery Experience

Development to Delivery Experience

Anand Selvaraj has supported projects from early-stage optioneering and FEED through detailed design, technical governance, assurance review, equipment interfaces and construction support.

GIS and OEM Product Understanding

GIS and OEM Product Understanding

Experience includes GIS substation solutions and product/interface exposure through major suppliers including Hitachi / ABB / GE-type HV equipment environments, supporting practical and supplier-aware design decisions.

Optimised and Cost-Benefit Led Design

Optimised and Cost-Benefit Led Design

GA Power focuses on solutions that meet client requirements while reducing unnecessary cost, avoiding over-design where possible and protecting the project programme.

Whole-Life Engineering

Whole-Life Engineering

Design decisions consider construction, operation, maintenance, access, safety, outage constraints, programme risk and long-term asset performance.

Sustainability and Responsible Engineering

GA Power should present sustainability not only as a corporate statement, but as a practical engineering principle: reducing unnecessary material, optimising layouts, reusing existing assets where feasible, supporting SF6-free technology and designing with whole-life operation in mind.
