EXPECTATION VS REALITY: THE PLD’S ROLLERCOASTER

OPINION

In this editorial, we seek to identify the reasons for the rapid change in the supply conditions of the Brazilian electrical system, which after reaching 60% of maximum storage in May and June, levels fell by 30 p.p. in four months in an environment of structural energy surplus.

REGULATORY

In this section, we discussed the return of tariff flags in December, which had been suspended until the end of 2020, and commented on other relevant issues that were discussed along the month.

WATER RESOURCES AND ENVIRONMENT

In this section, we comment on the Great Ethiopian Renaissance Dam (GERD), Africa's largest hydroelectric plant with 6.45 GW of installed capacity, whose reservoir has started to fill, which can bring insecurity to Egypt, but on the other hand, it can provide interesting benefits to the country.

INTERNATIONAL

In this month's international section, we discussed the process of liberalizing Vietnam's electricity market, which has entered its third phase of implementation and draw a parallel with the Brazilian electricity market from which lessons can be learned.

INNOVATION

In this section we comment on the challenges in the development of hybrid batteries, which combine capacitors and Li-Ion batteries, technologies that work in different ways, but that can produce a “super battery” if combined.

STRUCTURAL SUPPLY ANALYSIS

It presents the updated balance of demand and structural energy supply for the coming years and our traditional delay meter.
