Princeton Power Systems, a top developer of alternative energy systems and electronics manufacturer, is due to begin construction for an advanced renewable energy system that combines solar generation with lithium-ion battery storage and smart controls. The system is anticipated to be complete and functioning before the end of the year.

The system, which totals $1.5 million, is to be installed at the Company’s headquarters in New Jersey, U.S. The system will be connected to the PSE&G electric grid. The installation will incorporate a 200kwh energy storage system made from International Battery’s large-format lithium-ion batteries. The installation also involves a 200 kilowatt solar array. A 20 foot shipping contain, expandable to 1MWh of storage will house the energy storage system. Princeton Power System’s Grid-tied Inverter (GTIB) product will control the system and connect it to the electric grid. The installation demonstrates advanced smart grid functionality, including microgrid operation, demand response, power dispatch and frequency regulation.

“Integrating large amounts of alternative energy sources like solar and wind into the electric grid will require improved controls and electronics, and this in turn will make distributed generation much more valuable and effective,” said Darren Hammell, Executive Vice President of Business Development at Princeton Power. “Our goal is to show that this is possible and cost-effective today, using available technologies, while creating jobs and doing our part to help the environment.”

The solar array is expected to produce sellable Solar Renewable Energy Certificates (SREC) and offset a part of the building’s energy usage. The State of New Jersey’s Clean Energy Manufacturers Fund is financing the project, which will allow Princeton Power Systems to expand its advanced research and development, and manufacturing facilities for next generation power electronics.

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.
