New Balancing Mechanism entrants expected

National Grid ESO's project Wider Access - a project to increase accessibility to the Balancing Mechanism (BM) - is scheduled to go-live on 11 December 2019. Cornwall Insight has reviewed the recent activity of aggregated units and batteries in the BM and what impact this project will have on new entrants.

National Grid ESO's project Wider Access - a project to increase accessibility to the Balancing Mechanism (BM) - is scheduled to go-live on 11 December 2019. Cornwall Insight has reviewed the recent activity of aggregated units and batteries in the BM and what impact this project will have on new entrants.


Since June 2019 the volume of accepted actions on the BM from aggregated and battery Balancing Mechanism Units (BMUs) has risen considerably. In June, just over 2GWh of volume was accepted. By August, this had reached 9.1GWh, and accepted volumes have not fallen below 5GWh since. This trend is set to continue with the launch of the Wider Access Project.

Lee Drummee, Analyst at Cornwall Insight, said:

"The main objective of the Wider Access workstream is to allow non-traditional providers easier BM access. This is being facilitated by measures such as allowing BMUs to submit data at an aggregated level and through introducing Virtual Lead Parties that will be able to register BMUs from 1MW. In late November, Elexon announced that three parties are actively going through the qualification process to become a Virtual Lead Party.

"It is expected that new parties will take advantage of the changes made and increase the number of aggregated and smaller units active in the BM. Many of these players will be looking to add the BM to their present business cases in the hope of upside in what can be a volatile pricing environment.

"Like the Capacity Market and Balancing Services markets before it, the competitive landscape of the Balancing Mechanism is likely to change with the entry of smaller aggregated units."

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer

HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
