systems, etc.) while thoroughly comparing the products and services of indus-
try-leading manufacturers and suppliers, and then make the fnal decision of
As to the installation of the PV power system, ask the suppliers to send
materials and equipment to the job site directly as much and as early as pos-
sible upon request during the whole construction period, which would tre-
mendously cut the freight expense and improve the feld workers’ effciency.
Driving down costs in renewable energy power plant proj-
ects requires expertise and experience. In other words:
start right, work well and avoid errors!
I’ll assume a site was selected, technology too and
investment decisions are taken. So let’s get started! It’s
(almost) easy when done the right way. Each phase has
its own criteria and pitfalls. I’ll cite a list in 5 groups
using words quantity wisely (limit is 200) and skipping
Engineering: Gather specifc information on the site:
Sourcing: Maintain close relationship to most important suppliers; Align
project pipeline and mid-term sourcing contracts; Spend suffcient resources
defning contracts; Install high standard QC procedures.
Constructing: Spend suffcient resources controlling contracts; Review and
train before installing; Monitor closely; Safety frst.
Operating: Monitor closely; Have the years’ activities planned (not
guessed!); Have materials and spares available at lowest costs; Train service
staff; Safety frst
In my experience, while capital expenditures are more or less predictable
and do not leave too much room for reduction, operational expenses (OpEx)
are subject to high fuctuations sometimes diffcult to forecast. These can
be major contributors to the total cost of energy produced and reducing
them may be the most cost effective approach in order to mitigate the operational risks of energy infrastructures. However, capturing all the aspects
