Engineering Submittal Essential for a SPV Power Plant

Design & Engineering is an integral part of the implementation of the SPV power plants.

Engineering drawings & documents convey specifications, construction methodology, dimensions,

tolerances etc capturing the scope of works and presenting a first-hand idea on the final by product

that would be constructed.

Typical Master Deliverable list can be divided in two broad categories of Civil & Electrical which would

each entail the following:

The drawing should be able to serve site related changes, capture details of vast and remote access,

and be clear in nature to aid faster construction.

Apart from the above drawings the developer should also seek out for relevant technical

specifications, quality assurance plans, design basis reports, generation yield assessments,

implementation schedules & bill of material with quantities.
