From NOT A LOT OF PEOPLE KNOW THAT<\/a><\/p>\n\n\n\n

There has been discussion of solar farm projects which include battery storage. (Battery Energy Storage Systems, or BESS).<\/strong><\/p>\n\n\n\n

The claims of the developers and renewable lobby is that storage will help to make intermittent renewables work.<\/strong><\/p>\n\n\n\n

By coincidence Timera have just published this update, which reveals it is nothing more than a money making ploy:<\/strong><\/p>\n\n\n\n

Impact of new balancing platform on GB BESS<\/em><\/h3>\n\n\n\n

Batteries create value from harvesting price volatility.  The real time Balancing Mechanism (BM) has the most volatile prices in the GB market, yet battery (BESS) assets have captured limited BM value to date.<\/em><\/p>\n\n\n\n

BESS BM value capture has historically been impacted by:<\/em><\/p>\n\n\n\n

    \n
  1. Manual dispatch<\/u>\u00a0of flexible assets by the System Operator (ESO), disadvantaging smaller asset dispatch<\/em><\/li>\n\n\n\n
  2. The 15 min rule<\/u>\u00a0where BESS bid offer acceptances are effectively limited to 15 mins of duration (given issues with the ESO\u2019s visibility as to state of charge)<\/em><\/li>\n\n\n\n
  3. Skip rates<\/u>\u00a0where the ESO has consistently chosen higher priced assets over BESS in the BM (reflecting issues 1. & 2. above, but also real constraints that the ESO faces in managing the system e.g. locational requirements to use thermal assets).<\/em><\/li>\n<\/ol>\n\n\n\n

    There has been significant progress in 2024 in addressing these factors with the introduction of the ESO\u2019s new Open Balancing Platform and a relaxation of the 15 min rule.<\/em><\/p>\n\n\n\n

    In today\u2019s article we look at the impact of these changes on BESS asset dispatch in the BM.<\/em><\/p>\n\n\n\n
