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.

Chinese Solar Surge Fuels Overall Global Growth In Clean Energy Investment

World clean energy investment totalled $333.5 billion last year, up 3% from 2016 and the second highest annual figure ever, taking cumulative investment since 2010 to $2.5 trillion. An extraordinary boom in photovoltaic installations made 2017 a record year for China’s investment in clean energy. This outpaced changes elsewhere, including jumps in investment in Australia and Mexico, and declines in Japan, the U.K. and Germany. The figures up 3% from a revised $324.6 billion in 2016, and only 7% short of the record figure of $360.3 billion, in 2015.

European Parliament Gives A Resounding Vote In Favour Of Clean Energy In Europe

European lawmakers have called for a renewable energy target of 35% for 2030 – rather than the 27% which the European Commission proposed in 2016. The MEPs have now backed measures substantially raising the European Union’s clean-energy ambitions. By 2030, more than one-third of energy consumed in the EU should be from renewable sources such as wind and solar power. The measures are intended to help cut carbon dioxide emissions. The EU is the world’s third-largest emitter of greenhouse gases after China and the United States, releasing about 10% of global emissions.

US: Doubling Of Wind & Solar Capacity Possible By 2020 as Coal & Nuclear Drop

In the latest issue of its “Energy Infrastructure Update” (with data through November 30, 2017), the Federal Energy Regulatory Commission (FERC) notes that proposed net additions to generating capacity by utility-scale wind and solar could total 115,984 megawatts (MW) by December 2020 – effectively doubling their current installed capacity of 115,520 MW.  The numbers were released as FERC prepares for a January 10 meeting to consider U.S. Department of Energy Secretary Rick Perry’s proposal for a bailout of the coal and nuclear industries.

Vestas Sets 10.6 GW Record In 2017 After Year-End Surge; Ups Cashflow Guidance

Vestas has received a firm and unconditional order for 190 MW of 4 MW platform turbines in the U.S. taking the global order intake for the company in 2017 to 10.6 GW, surpassing 2016’s record order intake of 10.5 GW. The surge of orders at the end of the year has resulted in the company revising its guidance for free cashflow upwards. It now expects the free cashflow for 2017 to be €1.15bn-€1.25bn, as compared with the previous guidance of €450m-€900m. Markets have reacted favourably with the company share price experiencing an increase of 5%.
