Building a more sustainable community
Dublin, Calif., has recently completed an innovative sustainability program that is expected to significantly reduce the city's energy costs, stimulate the local economy, and create nearly $14 million in energy savings over its 25-year life. The entire project was executed without any up-front outlay of capital funding by the city, and is expected to generate substantial annual net savings.
With the help of Chevron Energy Solutions, the city has installed photovoltaic solar arrays at all of its facilities to offset energy usage. In addition, over 3,000 streetlights have been retrofitted with new LED technology to reduce energy use. Other improvements include upgrades to interior and exterior lighting at all city facilities, irrigation improvements at city parks, and improvements to air circulation systems at the civic center and library.
“This project has enabled us to take a significant step forward in achieving our ambitious environmental goals, while at the same time significantly decreasing the city's energy costs,” said Mayor Tim Sbranti.
Dublin selected Chevron Energy Solutions, a leader in delivering renewable and energy efficiency projects for local governments and educational institutions, to develop, design and construct the project.
“We have been proud to help the City of Dublin reduce their energy use and operating costs," said Jim Davis, president of Chevron Energy Solutions. "This collaboration demonstrates both visionary innovation and fiscal prudence.”
Since the city's incorporation in 1982, its population has increased as both residents and businesses found the benefits of calling Dublin home. Dublin is located approximately 350 miles north of Los Angeles and 35 miles east of San Francisco. From a population of approximately 14,300 in 1982, Dublin has grown to a resident population of 49,890 and has been one of the fastest growing cities in Alameda County.
Drax advances biomass strategy with Pinnacle acquisition
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).
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.
