National Grid highlights need for flexibility over summer


National Grid has predicted that greater flexibility will be required over summer 2017 to balance the electricity system during periods of low demand, and increased supply and demand variability. In its Summer Outlook Report 2017, published on Thursday 6 April, National Grid said that due to falling minimum demand on the transmission system, it anticipates that there will be periods of over supply during the summer. To counteract this the system operator plans to curtail flexible generation, as well as potentially instructing inflexible generators to reduce their output. Based on current forward prices it is “unlikely” that any coal-fired power stations will be able to generate a profit, whether providing baseload or running at peak. National Grid is also confident that the diverse range of available gas supplies will be sufficient to meet demand.
