Open Energi welcomes new CEO

Open Energi is pleased to announce the appointment of Andy Rees as Chief Executive Officer from April 6th.

Andy brings nearly 20 years of experience working in the energy sector across a variety of senior roles within technology development and deployment.  He joins Open Energi from LYTT, a real-time sensor software and analytics solution provider and another progressive bp Launchpad company. At LYTT, Andy held the positions of Chief Operating Officer and board observer and was responsible for commercial operations and delivery.  With a keen focus on the customer, he has an established track record of leading agile, evolving businesses to commercial success.

Andy joins Open Energi during an exciting period as it seeks opportunities to scale up, exploring how it can work with bp’s trading & shipping business and low carbon portfolio as they look to meet their net zero ambitions. 

Prior to LYTT, Andy held several senior positions across bp, where he played a pivotal role in modernising and transforming their approach to upstream technologies and led research and evaluation programmes for enhancing recovery.

Andy holds a PhD in Chemical Engineering from the University of Cambridge and a Masters in Chemical Engineering (MEng) from University College London.  He is a Chartered Chemical Engineer.

David Byard, VP of Commercialisation and Intellectual Asset Management at bp, said:

“The whole Open Energi board is delighted that Andy is joining to lead the company at this exciting time in its journey! Andy brings exceptional experience from within both a high-growth digital start-up and a corporate innovation environment. I’m personally looking forward to working with Andy and the Open Energi team as they continue to build and accelerate the business, delivering advantaged performance for our customers.”

Andy Rees, CEO of Open Energi, said:

“I am delighted to be joining Open Energi at this key moment in the energy transition when the need to enable the efficient and effective use of renewable resources is more pressing than ever. With the backing of bp Launchpad, I am looking forward to helping the Open Energi team scale the business.”

Open Energi support Scottish Water in Battery storage first

Scottish Water has completed work on its first large-scale battery storage project to accelerate its drive towards net zero emissions by 2040.

The flagship scheme, delivered by framework contractor Absolute Solar & Wind Ltd, is part of a £2 million renewables project which includes the company’s largest single solar energy array to date. 

Four vanadium flow batteries, manufactured by Invinity Energy Systems, capable of storing up to 0.8 megawatt hours (MWh) of energy will be used to store energy generated from more than 2,520 solar panels, with a combined output of over 1 megawatt (MW), which have recently been installed at the waste water treatment works that serve the city of Perth.

By enabling solar energy to be used at any time of the day or night, the battery system will allow around 94% of the renewable power generated to be used on site – a significant step forward in the company’s decarbonisation ambitions.

By combining battery storage and solar power, the carbon footprint of the treatment works will be cut by around 160 tonnes of CO2 per annum – the equivalent of offsetting 580,000 miles from the average passenger car. The scheme will also help to power the utility’s first rapid electric vehicle charging points which have been installed at the site; and will reduce energy costs of the treatment works by approximately 40%.

This installation is the latest investment by Scottish Water Horizons, the public utility’s commercial subsidiary, who are developing a programme of opportunities for battery storage across Scottish Water’s asset portfolio.

Scottish Water Horizons Business Development Manager, Donald MacBrayne, said:

“We’re excited to have our first battery facility up and running to help reduce emissions and tackle climate change. The ability to maximise green energy production as well as store and release this energy when we need it is a vital part of our journey to net zero.

“By harnessing this technology, we now have a much wider opportunity to install renewables schemes that were previously unviable due to grid constraints. It’s a massive step forward for us and will form an integral part of how we cut our emissions in the coming years.

“It’s fantastic news for the customers in Perth as they can now benefit from a treatment service with a significantly lower carbon footprint, helping them with their ambition to become the most sustainable small city in Europe.”

The utility-grade vanadium flow batteries were assembled by Invinity Energy Systems at their manufacturing and assembly facility in West Lothian. Invinity’s patented vanadium flow battery technology is already making its mark in the energy storage market world-wide as a safer, more durable and sustainable alternative to traditional lithium-ion batteries.

Matt Harper, Chief Commercial Officer at Invinity Energy Systems said:

“We are very proud to be supporting the decarbonisation of essential public infrastructure in the UK. Utility-grade energy storage, such as our vanadium flow batteries, has a key role to play in unlocking the low-cost, low-carbon energy we require to reach net zero while helping to shield companies from rising commercial energy prices.”

A key component to the success of the battery and solar hybrid scheme is the intelligent battery software and control system that coordinates the production, storage and release of the energy generated.  The digital optimisation platform, Dynamic Demand 2.0, supplied and installed by Open Energi, provides a steady supply of energy during periods of low renewable generation whilst keeping energy costs down.

David Hill, Chief Commercial Officer, Open Energi said:

“Open Energi are thrilled to be part of such a pioneering project. The use of vanadium flow storage enables Scottish Water to soak up a greater proportion of their on-site solar generation when compared to conventional lithium-ion storage. Our micro-grid optimisation tool, which uses highly localised solar, demand and wholesale energy price forecasting capabilities, ensures not a single drop of sun’s energy is wasted. When you look at the recent surge in power prices, driven by high gas prices, we see this type of ‘Energy as a Service’ proposition, which bundles zero carbon technology into a simple value proposition, becoming the norm for all energy consumers.”

The battery project in Perth joins a long list of renewables schemes already installed at many treatment works and other Scottish Water assets across Scotland.  

Renewable energy experts Absolute Solar and Wind delivered the onsite solar scheme earlier this year whilst adhering to ongoing Covid guidance.

Scottish Water has committed to reach net zero carbon emissions by 2040 with an interim target to host or self-generate three times its annual electricity consumption by 2030.  Almost 80 of the company’s water and waste water treatment works are now either self-sufficient or partly sufficient in their power requirements.
