2Q23 Operational Release

The 1.6% increase in distributed energy volume is due to weather conditions, 1 in addition to a lengthier billing period2 and improved employment and income conditions,3 leading to increased household consumption and an expending number of customers, particularly in the residential and commercial classes.

The Company saw a 2.9% increase in its customers count, at 2.9% in the captive market and 16.5% in the free market. O The large increase in free-market customers is the product of migrations from the captive market, with 148 customers at EDP SP and 143 at EDP ES.

• Rural: down 0.7% in the quarter, reflecting the negative impact of heavier rainfall (+83.2 mm), which discouraged the use of electric energy for irrigation purposes.

GENERATION

• HYDRO GENERATION

On a consolidated basis, the volume of energy sold was 1.276 GWh, own 14.1%, due to the disposal of the Mascarenhas HPP, completed in early December 2022. Ex- the effects of the sale of the Mascarenhas HPP, the volume of energy sold would have been up 3.9%. Considering unconsolidated assets,5 the volume of energy sold was up 3.4%.

The year's seasonal weighting curve is flat because of the reduced number of contracts executed for Enerpeixe and the profile of PPAs.
