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.

Wind: China Maintains Emerging Markets Top Spot Following 19.7GW Build Boom

Wind industry intelligence service A Word About Wind has launched its Emerging Markets Attractiveness Index report for 2018, which provides insight and analysis into the most attractive emerging markets for wind companies. The index, now in its second year, ranks the top 30 emerging markets that investors should consider when investing in wind in Europe, Africa, Asia and Latin America. The list considers factors including political and economic stability for investors, alongside the growth of electricity demand and potential for wind growth, in order to rank the countries by overall potential. As with last year’s report, China tops the list and the ongoing trade war with the US shows no sign of slowing China’s formidable growth.

Battery Boom: Wind And Solar Can Generate Half Of Worldwide Electricity By 2050

Coal is to shrink to just 11% of global electricity generation by mid-century, from 38% now, as costs shift heavily in favour of wind, solar and batteries. Wind and solar are set to surge to almost “50 by 50” – 50% of world generation by 2050 due to reductions in cost. “Cheap battery storage means that it becomes increasingly possible to finesse the delivery of electricity from wind and solar so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. The result will be renewables eating up more and more of the existing market for coal, gas and nuclear.”

Solar And Wind Provide 100% Of New Generating Capacity Additions In September

US – According to an analysis by the SUN DAY Campaign of data just released by the Federal Energy Regulatory Commission (FERC), solar and wind were the only energy sources adding new capacity to the U.S. electricity generation mix in September. Three “units” of new wind accounted for 363-MW while nine units of solar provided 339-MW.

EU Approves Ambitious Energy Efficiency Goals, Encourages Clean Energy Feed-In

Europeans will now be entitled to consume, store and sell the renewable energy they produce in line with ambitious targets set by the EU. The targets are to be reviewed by 2023, and can only be raised, not lowered. By making energy more efficient, Europeans will see their energy bills reduced. In addition, Europe will reduce its reliance on external suppliers of oil and gas, improve local air quality and protect the climate. For the first time, member states will also be obliged to establish specific energy efficiency measures to the benefit of those affected by energy poverty. Member states must also ensure that citizens are entitled to generate renewable energy for their own consumption, to store it and to sell excess production.
