Webinars

At IEA Clean Coal Centre webinars our expert authors give presentations on the findings of their latest reports. Webinars usually take place on the second Wednesday of the month at midday (UK Time). If you are unable to attend the event live, they can be viewed at any time after the event from this page.

Levelling the intermittency of renewables with coal - costs and risks is the subject for the next webinar, which will be presented by Dr Lesley Sloss on Wednesday 8 June at midday (UK time). 

Countries are setting ever higher goals for producing power from clean, renewable energies and some are actively turning their backs on fossil fuels. However, many of these regions are discovering the real challenges of trying to produce baseload power for public consumption from renewable sources which are, at best, intermittent, and, at worse, unpredictable and unreliable. Until large scale energy storage is available and affordable, baseload power from coal, gas, and/or nuclear will remain necessary in many regions for several more years. Obviously this baseload power is required when renewable output is low (when the sun doesn't shine and the wind doesn't blow). However, it is also still required to make up the balance of power in a diverse energy mix. Under the new energy policy regimes in many regions, renewable sources have priority into the grid and sit in the guaranteed dispatch mix in the base region which coal used to occupy. Coal has now been nudged into the dispatchable area of the mix, being asked to ramp up or down or even to idle or run beyond normal capacity, sometimes at short notice, to produce the balance of power required to maintain grid output. And whilst coal plants can run relatively flexibly, this does not come without cost. Most older coal-fired units were designed to run at steady output. Asking these plants to cycle and ramp puts stresses on the plant which can result in added cost, less efficient production, increased wear and tear and, in some cases, damage causing enforced outages for repair and/or upgrade. This webinar, looks at the stresses placed on coal-fired plants as they are asked to help levelise and counterbalance the intermittency of renewable sources, concentrating on the risks and costs. Case studies and examples of issues being encountered in the USA, the UK and Germany are included.

IEA CCC webinars are free to attend, but a one-off registration is required with brightTALK ltd, who host our webinar channel. Register and view our webinars by clicking on the title of the one you wish to attend, then scroll down and click 'Attend'.
