DA leader Mmusi Maimane wants Parliament to reconvene urgently in order to address the energy crisis.
Maimane asked South Africans to join the party in a march on the Union Buildings on Friday while at the same time requested the National Assembly urgently reconvene.
Maimane says in his letter to Speaker Baleka Mbete he asked that Parliament set up an ad hoc committee on energy.
The opposition leader called the energy crisis a national issue as opposed to an election issue.
Maimane and the DA have proposed a "cheaper energy bill" which they say will solve the country's energy issues.
The party proposes to move Eskom's transmission and grid capabilities to an independent state-owned entity (SOE) that will own and operate the grid.
The generation section would compete with other independent power producers (IPPs) on price and reliability for supply to the grid.
Maimane says they will be marching on the Union Buildings and will demand the Presidency respond within five days.
On Tuesday, the party will sit down with various DA mayors on the energy issue and the way forward.
