Its greenhouse gas emissions are likely to be 60% higher than Eskom’s new Medupi and Kusile coal plants.
This is apparent from the final climate change impact assessment for the proposed Thabametsi coal-fired power station, to be built near Lephalale, Limpopo.
Thabametsi was in the spotlight earlier this year when the North Gauteng High Court – in South Africa’s first climate change court case – ordered the Minister of Environmental Affairs to reconsider Earth Life Africa’s appeal of Thabametsi’s environmental authorisation, but this time with a climate change impact assessment for the power station.
The court confirmed that a climate change impact assessment needed to form part of Thabametsi’s environmental impact assessment (EIA) and should have been considered before a decision was made on whether the power station could go ahead.
This climate change impact assessment is the first of its kind for a coal-fired power station in South Africa.
It confirms that Thabametsi’s greenhouse gas emissions are going to be high – it will release 9.9 million tons of carbon dioxide equivalent (CO2e) per year, and will have a greenhouse gas emission intensity of 1.23 tons of CO2e per megawatt hour, roughly equivalent, if not slightly worse, than Eskom’s oldest coal-fired power plants.
The climate change impact assessment also looks at whether the proposed power station will cope with the impacts of climate change.
It shows that water availability and deteriorating water quality in the already water-stressed Lephalale area pose a high risk to the power station’s operation over its intended 30 year lifespan, especially because planned industrial expansion in the area will make water increasingly scarce.
Earth Life Africa's’s comments state, among other things, that:
Despite this, the climate assessment summary report inexplicably concludes that the power station’s overall impacts are of low to medium significance, and that Thabametsi should go ahead.
The findings of the climate change impact assessment are deeply concerning, given South Africa’s extreme vulnerability to the impacts of climate change and the fact that South Africa has made international commitments to reduce its greenhouse gas emissions.
Many countries in the world are not building new coal plants; are decommissioning their own existing plants; and are turning to cleaner and more efficient solutions like renewable energy – from solar and wind. These are very feasible options for South Africa with its abundant solar and wind resources, as research by the Council for Scientific and Industrial Research (CSIR) has demonstrated.
Earth Life Africa’s Makoma Lekalakala says: “It is not clear why the Department of Environmental Affairs (DEA) authorised Thabametsi to begin with, as it will have irreversible climate impacts. We hope that the findings of the climate change impact assessment now make it clear that this power station should not have been given approval.”
In accordance with the High Court order, the Minister, once she has considered the climate impact assessment and comments on it, must make a decision on whether to uphold or (again) dismiss Earth Life Africa’s appeal of the environmental authorisation.
In doing this, the minister can set aside Thabametsi’s environmental authorisation, uphold it (with or without amendments), or refer the application back to DEA for reconsideration. Until the minister makes her decision, Thabametsi’s environmental authorisation is suspended.
Centre for Environmental Rights attorney Nicole Loser points out: “As with all proposed new coal plants which have not adequately assessed climate change impacts, or which have been authorised to go ahead despite the irreversible climate change impacts, if the minister allows Thabametsi to proceed despite these impacts, our client will consider further legal action.
Either way, it seems imprudent to commit South Africa to a project that will emit greenhouse gas for at least 30 years, in circumstances when the revised Integrated Resource Plan for electricity – expected to be published early in 2018 – may substantially reduce the amount of coal in South Africa’s energy mix.”
Thabametsi, as a preferred bidder under the Coal Baseload Independent Power Producer Procurement Programme, is required to reach commercial and financial close by 3 November 2017. As things stand, apart from the suspended environmental authorisation, Thabametsi also does not have a generation licence, an air emission licence, or a water use licence.
This is a joint campaign which aims to discourage investment in new coal-fired power stations and mines; accelerate the retirement of South Africa’s coal infrastructure; and enable a just transition to renewable energy systems for the people.
