Plus Power's 565MWh 'shock absorber' BESS in Hawaii comes online


It comprises 158 Tesla Megapacks configured into 135MW/540MWh for capacity and energy use cases and another 50MW/25MWh of additional capacity for ‘fast frequency response’ to help keep the grid stable.

Brandon Keefe, Plus Power’s executive chairman claimed: “It is the first time a battery has been used by a major utility to balance the grid: providing fast frequency response, synthetic inertia, and black start. This project is a postcard from the future – batteries will soon be providing these services, at scale, on the mainland.” 

The announcement said it will be acting “…as an electrical “shock absorber” (a function) often served by combustion-powered peaker plants”.

Another major energy storage project which has been described as such a “shock absorber” is the 850MW/1680MWh Waratah Super Battery in Australia which is being deployed by system integrator Powin.

KES, Hawaii’s biggest energy storage project, was approved in May 2021 and financing for it was achieved by Plus Power six months later.

Customer-sited solar power has become so abundant that Hawaiian Electric, the main utility in Hawaii, needs to regularly curtail – i.e. pay owners to turn off – utility-scale solar and wind to keep the electricity system in balance. 

The utility’s modelling has forecast that thanks to the KES project it will be able to reduce curtailment of renewables by 69% over the first five years of operation, integrate 10% more new utility-scale renewables than previously modelled, and allow for continued growth in customer-sited solar. It is also expected to reduce consumer electric bills by an average of US$0.28 per month over its 20-year contract life.

The utility has been busy progressing the US island state’s clean energy and energy storage development goals, starting negotiations with 2.1GWh of energy storage projects in December 2023 and in May unveiling a long-term renewables plan which included adding add more than 3.7GW of hybrid solar, energy storage and firm renewables by 2030.

Plus Power said that by June 2024 it will have some 1,325MW/3,500MWh of energy storage online across the US, including projects which were part of a US$1.8 billion fundraise it concluded in November, the largest seen in energy storage in 2023.

(BIVN) – The winners of this year’s Hawaiʻi Coffee Association cupping contest have been announced. 

The Hawaiʻi Coffee Association’s 15th Annual Statewide Coffee Cupping Competition took place during the 29th HCA conference, held from July 18 to 20 at the Ala Moana Hotel in Waikiki. 

“We are thrilled with this year’s turnout and seeing such enthusiastic participation in our diverse range of presentations,” says conference chair Juli Burden of the Hawaii Agricultural Research Center. “This support is a testament to the dedication of the coffee community here in Hawaii.”

From a Hawaii Coffee Association news release:

Statewide Cupping Competition Results

A total of 103 entries, up from 68 in 2023, vied in the 15th Statewide Hawaii Coffee Association Cupping Competition. Brittany Horn, HCA cupping committee chair and co-owner of Pacific Coffee Research (PCR), notes the competition’s 51 percent higher turnout is likely due to a positive bounce-back after the 2020 introduction of Coffee Leaf Rust and a high-yield year.

“Additionally, the competition committee brought back the commercial division this year,” adds Horn. “In a similar manner to an auction, the commercial division requires a two-pound sample be submitted representative of a 300-pound lot.”

The annual competition received 20 commercial and 83 creative division entries. The top three scoring coffees of the 103 entries were in the creative division and all hailed from Kona. This division is reserved for smallholder farms with entries under the direct control of owners.

Taking first place overall was a fruit-dried (natural process), 36-hour anaerobic fermentation Geisha variety with yeast inoculation produced by Geisha Kona Coffee earning a record final score of 87.83 points. Monarch Coffee Farm entered a 36-hour ferment parchment-dried (washed) Geisha variety placing second with a score of 87.40.

Kona-based PCR (Pacific Coffee Research [PCR]) organized the competition utilizing a cupping panel composed of local and global coffee professionals led by Madeleine Longoria Garcia, PCR co-owner. “Judges from around the world applied to participate in this yearʻs competition and were invited based on their experience, training and opportunity for engaging with Hawaiiʻs coffee producers,” notes Longoria Garcia.

The panel of sensory judges included:

The panel employed the standard Specialty Coffee Association’s cupping methodology and scoring format. It is a form of scientific sensory analysis where coffees are evaluated and scored based on a variety of subtle characteristics: flavor, aroma, acidity, aftertaste, body, balance, overall cup experience, presence of sweetness, lack of defect and uniformity.
