Brazil: what's the real cost of PV energy?

Brazil: what's the real cost of PV energy?

The official auctions of energy produced by solar farms show that the price is in the range of R$ 100/MWh. (1 USD = R$ 4 in rough numbers). order to make solar energy feasible, we need to have "backup" energy from other sources so that when there is no sun the customer will continue to receive electricity normally.

A back up power plant has an associated investment of R$ 5 thousand/kW installed. Its monthly amortization is therefore around R$ 120/MWh.

Thus the cost of energy that comes from solar but with the backing of a "firm" plant reaches R$ 220/MWh. If the backup plant involves fuel (natural gas, as ANEEL is venturing) there will still be an extra cost.

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.

If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
