No, the Finance Minister does not intend to introduce legislation of such a nature for the following reasons:
In addition, this question betrays a fundamental misunderstanding of the way electricity is paid for in South Africa. Electricity users must pay for the electricity they use. In the case of customers supplied with electricity by municipalities, this means that users (including businesses and households) must pay the municipality for the electricity they use, and the municipality must in turn pay Eskom for the bulk electricity that they have purchased to sell on to their customers. National Government does not make transfers to municipalities to enable them to pay for electricity bought by municipal distribution customers. So it is not clear what source of funding the questioner is suggesting that funds should be deducted from and transferred directly to Eskom.
In line with the autonomy given to municipalities, the Accounting Officers is responsible for exercising prudent financial management at the institution, this is captured in section 60 and 61 of the Municipal Finance Management Act, 2003 (Act No. 56 of 2003) (MFMA). Similarly, Section 38(1)(c) of the PFMA states that the Accounting Officers of departments are responsible for the monies due by the department.
Creating an opportunity that take away the responsibility of the respective sphere of government will open the door for any creditor to approach national government for direct payment which is will be unmanageable especially in cases were disputes may arise as is the case of Eskom and some municipalities as well as municipalities and the Department of Public Works and Infrastructure.
