Michael Bironneau, Technical Director of Open Energi explains how artificial intelligence can be used to provide demand side flexibility more efficiently. Technology is changing the way we live. By 2020 […]
The third Power Responsive Conference will take place on 27th June 2017 at the Emirates Stadium, London. We look forward to welcoming guests from across the industry as we focus our attention on ‘Delivering the Future Together’. An agenda of expert speakers, exhibition, and breakout seminars will form the basis for an interactive day. If you wish to register your place at the conference, please visit our conference website via the link below.
The Power Responsive Flexibility Investor event took place on 10th May at Altitude 360 in London. Presentations from industry experts, Ofgem, and National Grid provided guests with insight into the latest industry activity with a view to addressing myths that surround energy flexibility. Please see our event summary where presentation slides can also be downloaded.
The Power Responsive Storage Working Group and DSR Provider Group took place on 13th and 21st March respectively. Please find the combined summary note from both working groups below. If you wish to be invited to either (or both) future working groups please contact email@example.com.
Camborne Energy Storage Ltd. (CES) is on a mission to deliver secure, low carbon power to the UK. The company’s Managing Director, Dan Taylor, explains how they’re helping to balance electricity supply and demand by deploying battery energy storage systems.
We have worked with several partners to successfully deliver a 500kWh battery storage project. The Tesla Powerpack installation – which is co-located with a solar PV plant in Somerset – has the capacity to provide power for over 500 homes.
Poweri were responsible for connecting the system to Scottish and Southern Energy Power Distribution’s 11kV network and demand-side aggregator, Open Energi, are managing its day-to-day operation to optimise performance and maximise value.
Unlocking value from battery storage
The system is making money in two ways: time of use discharging, which involves storing electricity generated during periods of low demand and releasing it when demand peaks, and Firm Frequency Response (FFR), which involves the battery automatically charging and discharging to help balance electricity supply and demand second-by-second.
This kind of smart flexibility is vital to support greater levels of renewable generation.
The system benefited from the solar PV plant’s existing export capacity but additional grid import was needed so that the system could still participate in FFR when the solar PV plant was not generating power.
A smart control strategy
Open Energi have worked closely with us to seamlessly integrate their Dynamic Demand software with the Tesla Powerpack. After a period of testing, Open Energi have applied machine learning and designed state of charge management techniques to deliver a control strategy which understands and responds to fluctuations in solar PV generation and electricity supply and demand to maximise revenues and minimise wear and tear.
This kind of smart flexibility is vital to support greater levels of renewable generation and the success of this project demonstrates the role of energy storage in delivering secure, low carbon power to the UK.
We have ambitious deployment targets with around 50MW of consented sites ready for construction. We aim to deploy further energy storage as stand-alone grid-connected assets, co-located with renewable generation and also as behind-the-meter solutions to major energy users throughout the UK to help make our electricity system fit for the future.
Power Responsive held a roundtable discussion with Trade Associations from a variety of energy related sectors. Discussion focused on how Power Responsive can work more closely with the energy market and business customer Trade Associations, and how the 2016 Power Responsive Annual Report can be developed further to encompass a wider set of metrics.

With a complex on-site generation set up, and a requirement to reduce energy costs and operational planning time, Kodak Alaris looked to flexibility as a smarter approach. David Jeans, Energy Manager for Kodak Alaris, explains how they worked with DONG Energy to implement a flexibility solution that cut resource time as well as energy costs.
Creating an operational strategy that uses our generation and consumption assets in the most efficient way can be a time-consuming process, often requiring manual data entry and complicated calculations. For pragmatic reasons, we were having to use broad averages rather than accurate half-hourly market information. A practical, low-cost solution was needed to help us respond to market information more effectively.
When I heard about DONG Energy’s approach to optimising site operations at a seminar it was a real ‘light-bulb’ moment. Their solution is unique – I’d never come across anything like it before, but it was the perfect fit for our needs. The software they’ve developed is cutting-edge. It’s cloud-based and uses algorithms to calculate the optimal run schedule for an operating plant. To do this, it analyses market signals in relation to operating constraints and asset availability. We enter plant information through the web portal, which is then automatically analysed to produce our optimum daily run schedule, detailing the commercially optimal way to operate equipment, schedule production, and generate electricity on-site or export to the grid. I’m able to take the information directly from the interface, print it out and hand it to our operational staff in our morning production meeting. Everyone finds it really easy to use as the solutions are always practical. It’s a very different plant now. Previously, we’d have a plan for the week that didn’t change all week because it was built on averages. Now we have a plan that changes from hour to hour and that really optimises what the plant is doing each day.
Accessing the right support
I have weekly calls with our Account Manager at DONG Energy to make sure we’re getting what we need from the solution. We also get to speak directly to the technical people who built the system, so they really know how it works and can quickly resolve any problems. From the word go, it’s been a collaborative experience and we’ve been able to establish great relationships with the technical support team at DONG Energy, both in London and in Denmark. Their expertise complements ours and they were extremely quick to understand the complexities of our site and what we were looking to achieve.
Through working with DONG Energy, we have been able to take full advantage of our site’s flexibility capabilities and have followed the system’s recommended run schedules to within 3%. As well as boosting resource savings through a reduction in daily planning time, we have optimised operational performance which has led to an 11% saving in energy costs.
I would definitely recommend flexibility solutions to other businesses which work similarly to ours. From a business perspective, the savings you can achieve using simple tools and techniques make it a no-brainer.
