SUPPORTING BRAZIL’S NATIONAL GRID POWER GENERATION PROGRAM\

An FG Wilson dealer has installed 576 x P675P5 generating sets at two power plants in Brazil.

Aruanã Energia SA was instrumental is supplying one of the world’s largest generating set installations.

The plant is powered by over 500 FG Wilson units. Aruanã Energia, one of the company’s key dealers in Brazil, installed and commissioned an impressive 576 x P675P5 generating sets over a nine month period at a site in the town of Igarassu, Pernambuco.

When combined, these generating sets have the capacity to supply a total output of 236 MW of standby power to the national grid in Brazil.

The power plant is expected to operate between 1000 - 2000 hours every year during times of peak demand and to provide additional power during the winter months. Aruanã Energia, successfully won the contract to supply two power plants, Pau Ferro (94 MW) and Termomanaus (142 MW), which were later merged on to the same site.

As part of this contract Aruanã Energia, were appointed to supply power via this installation for the next 15 years.

Aruanã Energia, were contracted to supply and install the following:

• 576 x P675P5 (baseload rated at 450 kW, 60 Hz, 440v)

•EasYgen 3200 syncronising panels

•Industrial silencers

•Battery chargers

•Motorized circuit breakers

•Ř Fuel transfer solenoids.

The installation was a difficult challenge due to the extreme weather conditions at the time and the rugged terrain. Pau Ferro and Termomanaus power plants were designed to be the most cost effective solution for standby/peak shaving applications for the Brazilian power market.

These costs savings are gained through the innovative use of highly efficient diesel engines as the main source of power.

Traditionally, larger more expensive industrial, locomotive or ship engines would be used in Brazil for standby/peak shaving applications.

This unique design was the most cost-effective solution available and was based on a 15% annual plant utilisation factor.

Some of its most impressive features include very low acquisition and installation costs, optimised fuel economy at all dispatch levels and low operations and maintenance costs.

The generating sets operate at 440v and step up to 34.5 kV transformers, which again step up to the 230 kV transmission grid line. A single plant operator remotely controls each plant, via a state-ofthe-art SCADA system which was developed specifically for this project by Aruanã and FG Wilson.

This advanced control system dispatches and regulates power from the generating sets as required, with a user-friendy interface. This provides tremendous savings in operating and maintenance costs over the lifetime of the power plant.

DOE GIVES AN AWARD OF US$32.6M FOR CARBON HUB

Colorado School of Mines, Carbon America and Los Alamos National Laboratory (LANL) were awarded $32.6 million from the U.S. Department of Energy (DOE) to advance the development of a carbon storage hub for the Pueblo, Colorado area.

The DOE’s Carbon Storage Assurance Facility Enterprise (CarbonSAFE) initiative aims to develop large-scale, commercial carbon storage projects with capacities to store 50 or more million metric tons of carbon-dioxide underground.

CarbonSAFE Eos was one of nine projects selected by DOE as part of a $242 million nationwide investment. It intends to reduce emissions from industrial and power plant emitters in the region and at the same time, create a communitycentric model for carbon capture and storage (CCS) from the ground up.

“The DOE partnership really allows us to add more capital into a project opportunity and do all the screening that we need to do to be able to see if this is actually going to be a viable carbon capture and sequestration project,” comments Brent Lewis, CEO and Co-Founder of Carbon America.

There Is Room For Further Chp Development Across The Usa

US$20M FOR NEW ENERGY PROJECT IN MINNESOTA & COLORADO

CHP is installed at more than 4,700 facilities across America, representing over 81 gigawatts - or almost 8 percent of the nation’s total electricity capacity. There are CHP systems in every state in the United States and Washington D.C., Puerto Rico, and the U.S. Virgin Islands. Despite CHP’s use for more than 100 years in the US, there is still much opportunity for growth. A number of market drivers make it an attractive energy option, reports the US EPA in a recent report: * Lower energy costs. CHP has lower operating costs than traditional, separate heat and power generation technologies due to its enhanced efficiency.

* Role in decarbonization. Because CHP produces fewer emissions than grid power generation, it can play a role in decarbonizing energy production, especially with the use of renewable and zero-carbon fuels. This can be important for hard-to-decarbonize sectors, such as industrial facilities with high thermal demands.

* Focus on resiliency. CHP systems can be designed to keep critical infrastructure (e.g., hospitals, military bases, wastewater treatment facilities) as well as other facilities operational in the event of a power outage or grid disruption.

* Availability of packaged CHP systems. Increasingly, standardized, factory-built, ready-to-install CHP systems are available for purchase and installation. These systems can make CHP procurement and installation simpler and quicker.

* Policy Support. A number of state and federal policies and financial incentives are available that encourage the market for CHP. In 2016, DOE estimated the remaining technical potential for new CHP systems across the country (technical potential is an estimation of market size constrained only by technological limits; it does not account for economic or market factors). Room for further CHP growth still exists across all sectors.

ARIZONA’S LATEST 250 MW/1000 MW ENERGY STORAGE PROJECT WILL GO ONLINE IN 2024

Construction has begun on a 250 MW/1000 MWh battery storage project based in Tolleson, Arizona. The partners from Salt River Project (SRP), Plus Power and the City of Avondale, say the Sierra Estrella Energy Storage facility will be the largest standalone battery facility in Arizona once it comes online in 2024.

Storage from the project will serve SRP customers during times of peak electricity demand and facilitate more renewable integration. The project will use Tesla lithium-ion batteries.

Sierra Estrella was one of two battery storage projects SRP announced with Plus Power in the Fall of 2022. The other, a 90 MW/360 MWh project called Superstition Energy Storage, is expected to be built in Gilbert, Arizona. SRP has reported its corporate goal of surpassing a total of 1,100 MW in battery storage by 2024.

The utility aims to reduce emissions (from 2005 levels) by more than 65 percent by 2035 and 90 percent by 2050. As a part of that plan, SRP will have retired approximately 2,600 MW of coal-fired generation by 2032. Salt River Project is a community-based, not-for-profit organization which provides affordable water and power to more than 2 million people in central Arizona.

Breakthrough Energy Catalyst has agreed to commit US$20 million in funding for two multiday energy storage projects under Xcel Energy.

$10 million would each support the two 10 MW/1,000 MWh ironair battery systems Xcel Energy is constructing at the sites of retiring coal plants.

Xcel’s development would allow for the long-duration energy storage to be built at the Sherburne County Generating Station in Becker, Minnesota, and the Comanche Generating Station in Pueblo, Colorado.

Both projects are expected to come online as early as 2025 and are subject to regulatory approvals.

The batteries will allow Xcel Energy to store renewable energy such as solar and wind when it is being produced and then later distribute the energy during periods of lower production.

This month (July, 2023) Xcel Energy signed an agreement with Ambri, a provider of Liquid Metal battery system.

This collaboration marks the field deployment of Ambri’s Liquid Metal batteries, showcasing their potential in a real-world setting. The 300kWh system will be jointly tested with Xcel Energy at SolarTAC in Aurora, Colorado, for a year to assess its capabilities and performance.

Xcel Energy and Ambri are set to embark on a 12-month test of the 300kWh Liquid Metal battery system at SolarTAC.

The installation is scheduled to begin in early 2024, with full operation expected later that year. The system will utilize the GridNXT Microgrid Platform at SolarTAC to integrate multiple energy sources, including solar and wind, inverters, load banks, and 3-phase distribution connections and communications.

This is Ambri’s first opportunity to showcase its Liquid Metal batteries in a utility pilot system deployed in the field. Additionally, it is the first evaluation and demonstration of these advanced batteries by a major U.S. utility. Xcel Energy and Ambri will explore various use cases, such as solar and wind integration.
