Flexibility Services

To meet evolving customer needs, we are developing smarter, more flexible network solutions to help mitigate the need for traditional reinforcement and reduce costs for our customers. This is cheaper for our customers as it enables us to delay expensive reinforcement work for as long as possible.

Resources connected to our networks could provide both additional capacity and additional generation to assist in key areas that have specific challenges during periods of network constraint.

We are exploring markets for flexibility with new and existing customers who are able and willing to control how much they generate or who can control their demand.

We welcome feedback, comments or questions on our flexibility tenders. Please contact our flexibility team at: Flexibility@spenergynetworks.co.uk

Flexibility Services Overview

Text transcript

Flexibility services is where a Distribution Network Operator (DNO), like us, pays a third party to operate assets in a way that’s beneficial to our network. Those third parties will be owners of generation assets or low carbon technologies (LCTs) such as wind turbines, battery storage, solar or electric vehicles, and we may ask them to “turn down” or up depending on the needs of our network. In other words, we might ask them to lower the power consumption of their assets for an agreed period to allow us to free up that capacity for use elsewhere, or we might ask them to use more power in areas where we have excess generation.

As the needs of our customers and communities are constantly changing, the requirements of our electricity network are too. The increased uptake of LCTs does often result in constraints on the network during periods of high demand. However, new technologies and connections can often lead to excess generation in other areas too. Flexibility therefore provides an agile, smart means of balancing our network to solve both of those challenges.

Flexibility Providers

We will look to procure flexibility services through competitive tenders where possible and the responses from the flexibility providers will be used to:

Identify the availability of flexibility resources in specific areas where flexibility could benefit the network.
Understand the capabilities and restrictions of these resources.
Evaluate the viability of using flexibility to meet network requirements.

Case Studies

Axle Energy

Axle Energy is a flex provider focused on distributed devices: EV charging, batteries, and heat pumps. Axle connects to these devices on behalf of OEMs or energy suppliers and optimises devices considering needs of the customer and the grid. Axle Energy founded in early 2023 by energy industry & software veterans has quickly become a large provider of distributed flexibility in Great Britain. Utilising EV chargers, batteries, and heat pumps, Axle is able to provide large amounts of domestic flexibility in the GB DSO markets including SP Energy Network’s.

axle_energy_case_study_diagram

GB DSOs have demonstrated that flexibility services are a cost-effective alternative to traditional methods like network reinforcement. By using flexibility, DSOs can manage grid stability and peak demand more efficiently, reducing the need for expensive infrastructure upgrades. Axle Energy focuses on distributed assets such as EV chargers, batteries, and heat pumps, which are perfect for DSO flexibility programs. These assets provide significant benefits to the grid and offer advantages to consumers, including lower energy bills, increased efficiency, and potential earnings. For flexibility service providers, the benefits include improved operational efficiency and new revenue opportunities. Axle is committed to demonstrating how these devices can enhance the distribution grid, ensuring a reliable and cost-effective energy future.

SP Energy Networks has been working with Axle over many years through the long-term tenders, and recently, in our Month Ahead Market. Our month ahead market allows flexibility service providers to bid in to flex opportunities across both our SPD and SPM license areas. Each month, new flex requirements are made live, enabling providers to bid into locations where their assets can provide demand turn down services. The Month Ahead Market provides quicker returns for flexibility providers and immediate value for consumers. By participating in shorter-term tenders, providers can respond rapidly to grid needs, optimize asset use, and generate revenue more frequently, benefiting both the grid and customers with timely and efficient flexibility services.

“A key metric for us is how quickly we can return value to device owners after they opt-in to flexibility. The Month Ahead Market allows us to participate with a much shorter delay, creating more value for consumers while responding to the short-term flexibility needs at SPEN. We consider the addition of Month Ahead to be a very positive addition to the DSO flexibility landscape.”

Pelle Jacobs – Axle Energy

Over the next few years, Axle hopes to prove that DSO flex is an enduring, reliable alternative to network reinforcement, enabling the distribution grids to connect distributed assets more cheaply and easily without the cost and delay of major infrastructure works. For SPEN, Axle has been a key participant across both our SPD and SPM license areas provider demand side flexibility in over 25 locations whilst utilising both EV chargers and domestic batteries – highlighting the ability for all types of controllable domestic technologies to participate in our DSO Flex Markets. Below you can see a snapshot of the Axle’s key stats in our MA market so far:

Enabling Flexibility with AMP

AMP are at the forefront of the energy transition with a mission to create a smarter energy future. They focus on two core areas: grid flexibility and heat decarbonisation. Since 2016, AMP has led the development of dispatchable electricity generation and storage systems, supporting the network when and where it’s needed most. AMP’s network of grid flexibility assets comprises over 200MW of battery storage, gas reciprocating engines, and the UK’s first High Voltage Electrode Boiler, all playing a pivotal role in balancing renewables, avoiding costly grid reinforcement, and ensuring security of supply.

SP Energy Networks has collaborated with AMP over multiple years through the long-term tenders, and now, in our Month Ahead Market. Our month ahead market allows flexibility service providers to bid in to flex opportunities across our SPD and SPM license areas. Each month, new flex requirements are made live, enabling providers to offer demand turn down services. For FSPs, this means optimizing asset use, responding quickly to grid needs, and generating revenue more frequently. Consumers benefit from lower energy bills, increased efficiency, and potential earnings. DSO Flex is now an essential service that allows FSP’s to improve the way they use electricity, and AMP will continue to support DSOs in their mission. Since the start of the MA market in the summer of 2024, AMP has become a key player participating in most monthly tender rounds with their gas reciprocators in the Lister Drive and Bromborough Constraint Management Zones.

“We are proud to be working in partnership with SPEN as one of their largest providers of flexibility services. We have found the DSO team to be helpful and engaging through both the contract and service provision phases. We look forward to providing SPEN with further flexibility services in the future.”

Quote from Steven Horton – AMP Clean Energy Operations Manager.

Although our current month ahead tenders on Piclo are a new service and a new type of product in the UK Flex markets, our procurement and performance teams in the DSO Flex department are dedicated to facilitating and growing the market. We offer and end-to-end solution with comprehensive support from the beginning of a FSP’s journey in flex, all the way to receiving payments after a dispatch month. This approach ensures that new providers can easily navigate the process, benefit from expert guidance, and quickly see financial returns. By participating in the Month Ahead Market, new providers can take advantage of streamlined procedures, responsive support, and the opportunity to contribute to a more flexible and resilient energy grid. This has allowed AMP to participate in our markets and most importantly, provide key flexibility solutions to two important assets in our SPM license area. We hope to continue to work with AMP to deliver more flexibility where required and below you can see a snapshot of AMP’s key stats so far from our Month Ahead market.

Empowering Local Authorities

In February 2025, SP Energy Networks’ Flexibility Team began a pioneering collaboration with Liverpool City Council (LCC) to explore how Local Authorities can participate in flexibility markets and unlock new value from their assets. One year on, this partnership has become a blueprint for how Distribution System Operators (DSOs) and Local Authorities can work together to accelerate the transition to net zero.

Understanding the Opportunity

Local Authorities hold a diverse portfolio of buildings, energy assets and community infrastructure, yet many face challenges when navigating the emerging flexibility landscape. For LCC, the ambition to reach net zero is clear, but understanding how flexibility services could support that journey required dedicated guidance, technical insight and a clear route through the end‑to‑end process.

Recognising this, SP Energy Networks committed to working closely with LCC to help them understand the opportunities available, the requirements for participation, and the potential benefits for both the council and the wider energy system.

A Hands‑On, Collaborative Approach

Over the past year, the Flexibility Team has delivered a series of workshops, one‑to‑one sessions and technical assessments designed to support LCC through every stage of the flexibility journey. This included:

Early‑stage exploration, helping LCC understand how flexibility markets work and where their assets could play a role.
Technical appraisal of council sites, assessing suitability, operational constraints and potential value.
Guidance on business case development, ensuring investment decisions were informed, realistic and aligned with LCC’s sustainability strategy.
Practical support navigating our flexibility trading platform, giving LCC the confidence to participate in live services.

This level of engagement has been essential in onboarding our first Local Authority into our flexibility platform. It has also provided invaluable insight into the governance structures, decision‑making processes and operational challenges that are unique to Local Authorities.

Learning That Unlocks Access for Others

Working so closely with LCC has helped SP Energy Networks understand what a typical Local Authority portfolio looks like, the internal approvals required, and the barriers that can slow or prevent participation. These insights are now shaping how we support other councils across our licence area.

As a direct result of this collaboration, we have:

Published our Local Authority Participation Guidance, a practical resource designed to help councils get started quickly and confidently.
Developing a tailored flexibility agreement that better reflects the needs, processes and asset structures of Local Authorities.
Created a dedicated 1‑to‑1 workshop offer, enabling councils to explore their flexibility potential with expert support.

Why Local Authority Participation Matters

Local Authorities have a critical role in delivering a smart, resilient and decarbonised energy system. By participating in flexibility services, councils can:

Optimise their assets and reduce operational costs
Generate new revenue streams
Support local network resilience
Strengthen their leadership in the transition to net zero

Looking Ahead

Our partnership with Liverpool City Council marks an important milestone in unlocking flexibility across our licence area. The learning, tools and guidance developed through this collaboration will help many more Local Authorities realise the benefits of flexibility and play an active role in shaping a cleaner, smarter energy future.
