Swedish energy company Vattenfall has selected Alfen to deliver a 20 MWh energy storage system for a new project in Uppsala.

Having built up a successful working relationship on two prior occasions, the two companies both expressed their satisfaction at being able to collaborate once more:

“We are proud to be selected by Vattenfall to supply our battery energy storage system, as a continuation of our long-standing relationship on both EV charging and energy storage,” said Stephanie Schockaert, Sales Manager at Alfen.

“Our prior projects for Vattenfall, that include a 3 MWh energy storage system at the Prinses Alexia Windpark in the Netherlands and a 12 MWh energy storage system as part of a new hybrid solar and wind farm, position us well to also successfully deliver this project.”

Similarly, Tina Ivarsson, Project Manager at Vattenfall, commented, “We are looking forward to working with Alfen on this project due to their extensive experience and the involvement of supplier Sebab.”

Bolstering grid capacity

The development of the project is expected to provide needed support to Uppsala’s grid and mitigate capacity issues.

Connected to operator Vattenfall Eldistribution, Alfen’s energy storage system will aid congestion by preventing electricity ‘bottlenecks’ and allowing surplus power to be stored for later use instead of simply being wasted. 

The system has been based by Alfen on BMW car batteries which are then arranged to form its ‘The BatteryConnect’ grid management solution. 

“Storage of electricity will play an inevitable role in our energy grid. It is needed to match energy production against consumption and to stabilise the grid due to increasing decentralised generation and the growing penetration of electrical vehicles.

“Already today, industrial battery storage is frequently used to mitigate the risk of the unpredictability of renewable energy sources,” said Alfen on its website.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
