Maduro speaks about a number of things in the above 30 minute speech from yesterday. Here's what he said about the Electric:

The first attack was made to the technology area of the Simón Bolívar hydroelectric plant (El Guri), which supplies electricity for 80 percent of the nation. Maduro, emphasised that after 70 percent of the service in the capital was restored, the vandals paid by the opposition physically attacked the La Ciudadela substation, located in the Baruta municipality, Miranda state, to shut down Caracas again.

Faced with the insistent situation of destabilisation, the dignitary ordered the Bolivarian National Armed Forces (FANB) to monitor the territory to guarantee the safety of the citizens. He went on to explain that the three phases of attacks came about as follows:

1) Cybernetic attack:

An attack on the computerised system of the company CORPOELEC at the El Guri hydroelectric plant.

A group of cyber warfare experts was used to recover the system. 
 
2) Electromagnetic attack:

Mobile devices with high frequencies were used to knock down communications.

3.) Physical attack:

The burning and direct bombings of substations and electrical stations

The president denounced that the sabotage is "a great violation of human rights in our country by the right wing, who celebrate national suffering."
