Pico Alto Highlights The Increasing Significance Of Geothermal In Energy Mix

EXERGY has taken part in the inauguration ceremony of the Pico Alto 4 MWe geothermal power plant held in the stunning scenery of the Terceira Island, in the Azores. The plant designed and built by EXERGY and the Portuguese company CME for EDA RENOVÁVEIS, owned by EDA, the Azores power utility company, is now in commercial operation providing green baseload electricity to meet the island’s energy needs.

Participating at the inauguration ceremony, chaired by the President of the Regional Government of the Azores Vasco Cordeiro, Marco Bonvini COO of EXERGY commented:  “We are very proud of the successful completion of this challenging project. Pico Alto represents for us a great example of how innovation in greentech can provide sustainable solutions to satisfy people energy needs and contribute to improving the energy economics in a remote and isolated site of the planet. We see many opportunities to apply our technology in remote environments and Pico Alto is a good starting point and an excellent reference.

Carlos Alberto Raposo Bicudo Ponte, member of EDA Renováveis Board of Directors declared: “The Pico Alto Geothermal Power Plant inauguration is the first milestone for the commercial geothermal exploitation startup in Terceira Island, increasing the diversification of the power generation mix and boosting the contribution from renewables. The construction project was a technical and management challenge, with several contractors working at the same time and, on some occasions, in harsh climate conditions. This was effectively overcome thanks to the close cooperation from all the high-specialized teams, where EXERGY assumed successfully the lead role. We are very pleased with the initial production results.

For the first 2-months of operation, the Pico Alto power plant has been providing a stable and reliable supply of 4 MW of electricity to the grid. Maintaining this performance in 2018, the annual production of Pico Alto power plant will likely surpass the estimative made before the construction of the power plant. Thus, the geothermal contribution will probably exceed 10% of the electricity needs of Terceira, relieving this part of the power production from thermal groups, where fossil fuels are consumed, hence ensuring savings to the economy of the Azores, as well as environmental benefits, reducing the greenhouse gas emissions to the atmosphere.

The 4 MWe binary plant utilizes a geothermal high enthalpy resource, exploiting the heat available both in steam flow and geothermal brine. For this challenging project located in a remote site, in the centre of Terceira Island, 1500 Km off Portugal mainland, the Consortium EXERGY – CME supplied a turnkey solution, including the engineering and construction of the gathering systems, the air-cooled ORC unit equipped with EXERGY Radial Outflow Turbine and all balance of plant equipment.

Thanks to a tailored and efficient cycle design and the EXERGY’s proven Radial Outflow Turbine technology, the plant has reached the highest possible conversion efficiency producing up to 4.9 MW of electricity, with an average of 4.5 MW, thus overperforming on the values guaranteed to the client. By means of Pico Alto geothermal plant, EDA Renováveis is now providing a sustainable and reliable source of electricity to more than 56,000 inhabitants of Terceira, meeting up to 10% of the island electricity needs.

EXERGY is the developer and manufacturer of Organic Rankine Cycle (ORC) systems with the pioneering Radial Outflow Turbine technology. EXERGY’s proprietary technologies, covered by a number of patents allow for greater energy production via the exploitation of previously unusable heat sources from geothermal, waste heat from industry, biomass and concentrated solar power. The Company is part of the Maccaferri Industrial Group and sitting within the SECI Energia holding. From the headquarters in the north of Italy (Milan), EXERGY exports and implements its technology worldwide with a particular focus on high growth potential markets such as Turkey, South-east Asia, North and South America.

IRENA: Innovation Front and Centre, As Leaders Shape the Future Energy System

Participants from more than 80 countries explored the disruptive innovations in digitalisation and decentralisation that are transforming energy systems around the world. Remarkable cost reductions driven by technological innovation and an increasingly conducive policy environment have made renewable energy increasingly competitive with conventional fuels in many parts of the world. In parallel, innovations such as the Internet of Things, blockchain, artificial intelligence, smart charging of electric vehicles, and hydrogen power and storage are making energy systems increasingly integrated and flexible and are supporting the transition to a renewable-powered future.
