Flores Island, Portugal
PowerStore in the North Atlantic Ocean
As the crystal clear waters of the Atlantic Ocean play their melodic songs lapping against the shores of Flores Island, Portugal, there is a real buzz of excitement spreading through the local community. Darwin based company, Powercorp Pty Ltd, has designed a ‘Wind/Diesel/Hydro/PowerStore system’ that is the first of its kind in the world!
Powercorp’s Marketing Manager Will Galton said, “Powercorp’s primary role in the Azores Wind/Diesel/Hydro project was to upgrade the current power station with the newly developed flywheel energy storage system, PowerStore. The installation of Powercorp’s new technology will enable the local utility Electricidade dos Acores to maximise the wind penetration into the Power Station on the island. It is an exciting time for all involved as this project had been in the planning for some time.”
Electricidade dos Acores is an innovative energy provider to the Azores archipelago located in the middle of the North Atlantic Ocean, roughly 1500km west from Lisbon. There are nine Azorean Islands that EDA provide energy to with their environmental friendly wind/diesel/hydro power stations. With the addition of Powercorp’s new technology, EDA is demonstrating their commitment to renewable power generation.
Powercorp is working with the local power quality engineering company QEnergia to assist with the project logistics. QEnergia are responsible for the installation and local content of the Flores Island project.
PowerStore is a flywheel based energy storage system that has been specifically designed to provide peak lopping and spinning reserve and overcome transient and cyclic loads on grid connected or isolated systems.
The PowerStore connected to the Flores power system operates fully automatic aside the manual controlled power stations. At the second installation in the neighbouring island Graciosa, Powercorp will also provide a newly developed control system that integrates the renewable energy with diesel generation and PowerStore so that excess renewable energy is not wasted. This PowerStore Integration Package automatically controls and monitors all diesel generator sets, wind turbines and PowerStore. It also allows the diesel generator and wind turbines to be operated automatically without human intervention.
The two Enercon E-30 wind turbines currently operate as negative load to offset diesel fuel. There are inherent problems that occur with these sorts of configurations. Wind speed frequently goes through gusts and lulls, and if this natural fluctuating wind speed isn’t managed sufficiently it can result in wasted renewable energy, a lack of operational efficiency and poor power quality leading to supply outages. The technologies in PowerStore control can overcome these inherent problems.
Since the commission of PowerStore in October, fewer diesel generators have been required during periods of high wind excess resulting in the reduction of Green House gas emissions and diesel cost savings. Compared to conventional Wind/Diesel/Hydro installations the excess renewable energy is not being wasted, making Powercorp’s technology superior.
The combined project value of Flores and Graciosa is in excess of $AUD1.6 million. The project has great potential, leading to further sales of this kind.
Powercorp has received enquiries from the mining sector regarding the possible application of PowerStore in their power quality challenged industry. An installation is planned for the end of 2005. The winder at an underground mining operation requires an 8.5MW demand shift over a 120 second period. The Installation of just one 1MW PowerStore system will reduce total demand shift from 8.5MW to 6.5MW and allow the independent power provider to reduce the amount of diesel based spinning reserve by at least one 1MW generator.
PowerStore is the result of 18 years of Research & Development and fieldwork. Using its extensive experience Powercorp has designed and operated small diesel power stations in the Northern Territory to larger Wind/Diesel systems in the Antarctic.
