UK aggregator Kiwi’s Tesla battery now


Cardiff considers new district heating system


Trident Park produces 30MW of electricity, sufficient to power 50,000 homes, and was designed so that it could produce both heat and power. It is owned and operated by


Viridor, whose managing director of major contracts Chris Jonas said: “Our view is that all waste should be given a purpose and valued as a resource rather than rubbish.” Cardiff’s cabinet will be


Cardiff City Council is set to launch a £26.5m district heating scheme for public and commercial buildings using energy generated by burning non-recyclable waste. Its cabinet is considering using power from the Trident Park Energy Recovery Facility, which burns non- recyclable waste from nine local authorities. Cabinet member for clean streets and the environment Michael Michael said: “This is an exciting opportunity for


Cardiff to develop new low- carbon energy infrastructure, fuelled by existing assets and facilities in the city.” Michael said the project could save 5,600 tonnes a year of carbon, based on an assumed 5% saving on energy costs for the city buildings which are connected to the network. But the scheme would depend on funds from the UK and Welsh Governments, and the council’s ability to strike long-term contracts with users of the heat.


asked to allocate an initial £4m towards the scheme, subject to the remaining money being secured from the Government and private sources. The council said it was like-


ly to become a major share- holder in an independent company created to own the heat network. Based on studies made, Cardiff would see heat pipes connected to public buildings south of the railway line that runs through the city centre, together with construction of a back-up facility for times when Trident Park is closed


Piloting Europe’s first biomass capture and storage (CCS) project ­ Drax is now in


UK demand response and energy resource aggregation company Kiwi Power has completed its lithium-ion 4MW / 4.8MWh Tesla battery at Cenin Renewables in South Wales. The battery took three months to build in order to provide


firm frequency response (FFR) to National Grid after winning a two year contract offering 24-hour-availability at £19/MW (US$26.61) per hour to commence on 1st February, 2018. The 4MW Tesla battery is located alongside a number of integrated clean technologies at Cenin Renewables’ Parc Stormy site in Bridgend, which hosts a low carbon cement facility, a 735kW solar installation, an anaerobic digestion plant and a wind turbine. The battery is managed by KiWi Power and represents


the first of its size and revenue structure to be brought forward by the company. While this contract precludes the storage facility from performing grid charge avoidance, KiWi Power’s head of energy storage Stephan Marty said Cenin Renewables would be able to share in the immediate revenues as well as future opportunities. The project has also been entered into pre-qualification


for the capacity market - through which payments are made for generators to reserve some of their available capacity for dealing with stress events on the grid and to ensure reliability and security of supply to the grid - which could offer a revenue stream for the project from 2021/22. Parc Stormy originally intended to employ a 10MW


battery from Alevo in one of two projects planned by KiWi Power. However this was changed to the 4MW Tesla system. Martyn Popham, director of Cenin, commented: “We are pleased KiWi chose to invest at our Parc Stormy site in Bridgend which is another important step in our goal to demonstrate that by integrating renewable generation on one site you can deliver a reliable sustainable power source whilst providing much needed local economic development.” The project represents a first for KiWi Power in the financing and development of a battery storage facility of this size. Martyn explained that while the investment appetite remained high for projects like this, changes to embedded benefits, National Grid services and derating for batteries in the capacity market had caused previous uncertainty in the market.

partnership with CCS specialists from the University of Leeds

rax is investing in Europe's first biomass carbon capture and storage (CCS) project, having announced a partnership with CCS specialists from the University of Leeds


to pilot "new technology" at its North Yorkshire power plant. In order to achieve CO2 capture development and the concept that a negative emissions industry could one day play a key role in a net zero emission economy, the energy firm said it was partnering with C-Capture - a spin out from the University of Leeds - to invest £400,000 in "what could be the first of several pilot projects" at Drax to deliver rapid, low cost demonstration of BECCS (bioenergy CCS). The companies have said it could make the electricity produced from the biomass units at


Drax Power Station carbon negative by removing more CO2 from the atmosphere than the facility creates from the process of sourcing and burning wood pellets. Will Gardiner, CEO of Drax Group, said that in order to achieve the global climate targets set


out in the Paris Agreement negative emissions were a "must", and that BECCS would prove a leading technology in helping to achieve that aim. Comments Gardiner: "This pilot is the UK's first step, but it won't be the only one at Drax,"


said Gardiner. "We will soon have four operational biomass units, which provide us with a great opportunity to test different technologies that could allow Drax, the country and the world, to deliver negative emissions and start to reduce the amount of carbon dioxide in the atmosphere." Drax Power Station is the UK's largest, with three of its units operating to use biomass wood pellets as a fuel source after being converted from coal over the past decade.
