It has been a year since the largest battery in Britain opened in Bedfordshire.
The substation in Leighton Buzzard provides back up energy for the National Grid.
UK Power Networks says the two year trial to store electricity on a large scale is "going well".
Martin Wilcox, from UK Power Networks, said: "The project has been carrying out a wide range of individual service trials, aimed at exploring the performance and relative value of different kinds of storage methods.
"While there have some teething issues due to its first-of-a-kind nature, to date it has clocked up more than 1700 hours' operation in commercial markets and we have learned a lot about typical performance of grid-scale storage."
A teenager from Leighton Buzzard has been detained for six and a half years for a "vicious attack" on a man that he committed when he was 14.
The boy, now 16, broke into a former pub in Heath and Reach in September 2014 and brutally beat a man, who was suffered serious injuries.
He pleaded guilty to wounding with intent to cause grievous bodily harm, conspiracy to commit arson and conspiracy to commit criminal damage.
He was sentenced to six and a half years in a detention centre on Wednesday. The judge said he would have been jailed for 13 years been over the age of 18.
It is believed the teenager was associated with an older man that was behind the attack. The motive remains unclear.
“This was a horrendous assault that inflicted horrible injuries on a man that quite frankly is lucky to be alive.
We are pleased the instrument of this despicable crime has been detained with a lengthy sentence for a juvenile; however the instigator is yet to be discovered.
We are committed to ensure the person behind this attack is brought to justice and ask anyone that has any information that could assist our investigation to come forward in confidence.”
