South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) started in 2011

Integrated Resource Plan (IRP) 2010

• Promulgated in 2011, the IRP developed the preferred energy mix with which to meet the forecasted electricity needs over a 20 year horizon

• The plan included 9.2 GW of wind, 8.4 GW of solar PV and 1.2 GW of CSP by 2030

Ministerial Determination

• In May 2011, the Department of Energy (DoE) gazetted the New Generation Regulations under the Electricity Regulation Act (ERA) and made a determination for new energy capacity

• Second determination was made on 18 August 2015

IPPPP

• The IPPPP is a key vehicle for securing electricity capacity from the private sector for renewable and non-renewable energy sources as determined by the Minister of Energy

• The DoE, National Treasury (NT) and the Development Bank of Southern Africa (DBSA) established the IPP Office for the specific purpose of delivering on the IPP procurement objectives

• Since 2011, there have been 5 main Bid Windows (BW 1, 2, 3, 3.5, 4) contributing 6.3 GW total and recently an additional BW 4 Expedited, contributing 1.8 GW

• Power Purchase Agreements (PPAs) signed for BW 1,2,3 and 3.5 (1 project)

Overview of South Africa’s REIPPPP

The REIPPPP is designed to contribute to meeting the national renewable energy target while encouraging foreign investment and developing socio-economic and environmentally sustainable growth

• To date, renewable energy projects in South Africa have resulted in 20 000 jobs for South Africans and have attracted R 192.6 billion in investment.

• Furthermore, IPPs have committed a total of R 19.1 billion toward socio-economic development initiatives within the communities in which they operate, thereby positively contributing to livelihoods and income generation

• The main evaluation criterion for the bid selection process is pricing, with a 70% weighting, and a 30% weighting for other factors such as job creation, local content and black economic empowerment

• Prices have dropped over the four bidding phases with average solar PV tariffs decreasing by 83%, wind by 59% and CSP dropping by 43%

• The REIPPPP includes onshore wind, solar PV, CSP, small hydro, biomass, biogas, landfill gas, small hydro and cogeneration (from agricultural waste / byproducts)

The South African Department of Energy (DoE) has already allocated a total of 8.1 GW of renewables (mainly wind and solar photovoltaic – PV) for procurement from Independent Power Producers (IPPs)

• … of this, 6.3 GW have achieved preferred bidder status

• … of this, 4.0 GW have financially closed and signed the Power Purchase Agreements with Eskom

• … of this, 1 460 MW of wind, 1 474 MW of solar PV and 200 MW of CSP were operational and fed energy into the grid by Dec 2016

Morning & evening peak-hour Contribution Ratios

Wind Solar PV Base-load Plant

Wind and solar PV morning and evening peak-hour contribution ratios (for all hours from Jan-Dec 2016) show that:

• Wind contributes 13% more energy during the evening peaks than it does during the other hours of the day

• Solar PV contributes 49% more energy in the morning peaks than it does during the other hours of the day
