Hawaii expands solar production and storage capacity with 260MW projects
Seven solar projects with a total capacity of 260MW are being set up across Hawaii to boost the state’s energy production as well as storage capacity.
The planned projects will be located on Oahu, Maui and Hawaii islands, with two projects being developed by Maui Electric Co totalling 75MW with a storage capacity of 300MWh, according to Hawaiian Electric Co (HECO).
HECO says that negotiations for the projects are currently ongoing and residents of localities are being consulted. Contract negotiations will be completed by the end of the year and proposed PPAs will be submitted to the Public Utilities Commission.
The total of 260MW set to be produced by solar will reportedly be enough to displace around 1.2mn barrels of oil.
Shelee Kimura, Senior Vice President of Business Development and Strategic Planning at Hawaiian Electric, said: “These large scale solar and battery projects will accelerate our renewable energy drive at some of the lowest prices we’ve seen to date.
“With support from our communities, these projects will reduce our reliance on fossil fuel and cut greenhouse gas emissions while benefitting all with low-cost renewable energy.”
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.
