SP Energy Networks has accepted bids of 555MW of flexibility services following its Spring round of tendering.
The company said it will build on this success with a second flexibility tender this year in a bid to drive innovation forward in the industry.
Flexibility involves working with customers who can control their electricity demand or how much they generate, the company said.
This unlocks capacity in the existing infrastructure, meaning greener technologies such as electric vehicles and heating systems can connect to the network more quickly, it added.
In its latest round of tendering, SP Energy Networks issued a call for flexibility services for the period between 2023 and 2028.
In total 1.4GW of capacity was sought at all voltage levels with 555MW of bids now being accepted.
These bids, in addition to the capacity it has already contracted, could provide over 700MW of flexibility services.
In its second tender this year, SP Energy Networks is seeking 110MW flexibility services for the next three years.
SP Energy Networks acting head of DSO Gerard Boyd, said: “The response to our latest flexibility tender is extremely encouraging, and is a clear sign that the market is becoming more aware of our requirements and the opportunities that flexibility services represent.
“Flexibility will play a major role in the development of a smarter energy network, and I’m proud we’re at the forefront of developing this emerging market.
“We are exploring flexibility as a solution for a range of network challenges, considering it alongside smart solutions and network reinforcement, ultimately selecting the most cost-effective solution for our customers.”
