#Sona2015: Will load shedding interrupt Zuma?
Eskom says it can't make any promises to keep the lights on during Jacob Zuma's Sona.
JOHANNESBURG/CAPE TOWN - Eskom says it'll do it all it can to keep the lights on today and during the State of the Nation Address (Sona).
The utility can't make any promises though as the national grid remains under strain.
Stage two load shedding kicked in last night from 6:00pm to 10:30pm.
The parastatal's Khulu Phasiwe says they're closely monitoring the power system.
"We're urging all customers to continue to assist us where possible so we can continue to reduce the severity or the duration of load shedding."
This is the third time this week that the power utility has implemented load shedding.
Several generators have been taken offline for maintenance and the power giant says the current heatwave is making it more difficult to keep up with the demands.
Phasiwe said, "It means that consumers could be load shed twice a day depending on the schedules and who your supplier is."
Many will be waiting to see whether the red berets make good on their promise to interrupt his speech.
Julius Malema's party will use the president's big night to ask him when he intends repaying part of the public funds spent on upgrading his Nkandla home.
This year's Sona is shaping up to be a political showdown.
But does this mean more people will be tuning in to watch the event on television?
"The countdown clock that the EFF have been using on their own website indicating a potential explosion of protest in Parliament certainly has added to the interest in Sona from a domestic audience."
He believes South Africans will also want to hear about Zuma's plan to address the electricity crisis.

President Zuma is expected to address the country's electricity woes when he speaks this evening.
With load shedding now a daily occurrence around the country, Zuma will be accused of denialism if he doesn't mention it in his speech tonight.
He may want to use the occasion to explain how government sees Eskom funding itself when on a long term sustainable basis.
The president also knows that one way to wrestle the initiative from any young political upstart is to make a big policy announcement.
This means there may be a surprise or two in the works this evening.
Zuma has a date with the nation at 7pm tonight.
