Many other European countries – such as France, Switzerland and the UK – source a proportion of their power through these ‘day-ahead’ or ‘intra-day’ markets. This helps the market to adjust to the fact that on sunny days, there is cheap and abundant solar power. For example, Germany’s grid sources a proportion of its power only 30 minutes before delivery. Similarly, in India, there are some efforts to revive the financial health of indebted electricity distributors by allowing them to source lower-cost renewable energy rather than more expensive coal, as dictated by existing PPAs.Īnother approach is to create power markets with more dynamism so that utilities can simply pick whichever is cheapest. For example, Germany is negotiating with producers of lignite – often referred to as brown coal – for early closure and the Asian Development Bank has a pilot in Indonesia and the Philippines for the early retirement of coal through a newly developed ‘energy transition mechanism’.

Figure 3: Inflection point (price of electricity from new power plants), 2009-2019 Instead of being able to switch to the cheaper option that would benefit electricity consumers by reducing bills, the utility is legally obliged to keep sourcing from the coal generator until the PPA expires. At that time, renewable energy was more expensive, and a long-term contract with a coal generator might have been viewed as the stable and secure choice.īut fast forward to 2017, and suddenly, solar PV had out-performed coal in terms of cost per unit power (see Figure 3). They force a utility company to keep sourcing power from coal even when low-cost alternatives may be available and economically sensible.įor example, in the early 2000s, it may have made sense for a utility company to agree to a 25-year contract to source electricity from a coal-fired power station. Many PPAs for coal are like fossils: they reflect market conditions, expectations and prices of the past.
