49.9 MW and thermal storage in a new generation plant


The OHL group’s industrial division is in its final phase of executing the construction of the Arenales CSP plant, and is currently in possession of the installation’s definitive start certificate. The CSP plant uses parabolic trough collector technology, has 49.9 MW of capacity, and is just waiting for the final jobs to be completed before coming on line by the end of this year.

Amongst the CSP technologies currently in commercial operation, parabolic trough remains the most widely deployed and mature technology, accounting for as much as 95% of global installed CSP capacity. Despite profiting from phenomenal development over the last three decades, parabolic trough remains too expensive at a time when the costs of PV and wind energy are declining, while gas prices are also bottoming out. How will the technology maintain its mid-to-long term market share, and where do cost-reduction opportunities lie?

In the article below, based on a document recently published by CSP Today, the issues are discussed at length.

As detailed in CSP Today’s Parabolic Trough Technology Report 2014: Performance and Thermal Storage, the current global portfolio for the parabolic trough industry features 67 operating plants, spread across twelve markets around the world. Together these plants represent 95% of the total global CSP installed capacity, while parabolic trough plants under construction and development amount to 1.85 GW and 1.08 GW, respectively.

The future supply of fresh water is becoming a concern in the developed world and in particular in countries in the MENA region where the situation is dramatic. There, its scarcity has made it an invaluable resource for centuries, a situation that is aggravated by the region’s changing demography, industry and living standards. In many countries throughout the MENA region large amounts of freshwater are currently produced by desalinating seawater, using expensive fossil fuel energy as the main energy source. In most cases, fuel is supplied from the country’s own oil and gas resources or, even worse, from imported fuels.

The unique properties of CSP, along with the excellent solar resource found in the MENA region, offer a huge opportunity for CSP technologies to provide reliable fresh water production, either through thermal processes (Multi-Effect Distillation) or through electricity driven processes (Multi-Stage Flash), replacing the use of fossil fuels.

This article discusses the key findings in the CSP Guide on industrial applications.

Applying the ESCO model to office buildings seems to be limited to major, Government-supported projects acting within the 3000AGE programme. However, the private sector is aware of the advantages of externalising energy services and is moving in this direction. The Housing Association of the MASTERS I Madrid building is a good example.

The building is in the tertiary sector, with 17 above-ground storeys, on Avenida General Perón, next to the Paseo de la Castellana, and is used as offices. The building is an architectural reference in the city thanks to its curtain wall construction. As of June this year, it is also a reference for having modernised its thermal production facilities using the energy services model.

This intervention, with performance levels guaranteed by contract, enables it to comply effortlessly with the saving goals set in the Kyoto protocol.

The Gloria Palace hotel chain has three properties on the island of Gran Canaria: San Agustín, Amadores and Royal. All three hotels use propane as an energy source for their heating requirements. San Agustín and Amadores also have thalassotherapy facilities, which involves keeping several swimming pools at a temperature of about 35 ºC all year round. The energy efficiency project consisted of setting up an integrated energy service based around two biomass thermal units in the San Agustín (2×450 kW) and Amadores (600 kW) hotels, operating with biomass from pallet chips.

The savings made were used to cover other improvements in the hotels, these being the installation of two new cooling units with heat recovery in the San Agustín and Amadores hotels, a new integrated control system and refurbishment of the heat and cold distribution room in the San Agustín Hotel, as well as a system to monitor consumption in all three hotels.

All this has led to signing a 5-year energy services contract for the sale of useful heat and cold savings to the customer of €150,000, around 20% of their former energy bill.

Solar collectors at the Husa Princesa hotel in Madrid

Details of the government’s much awaited PIMASOL Plan were finally revealed at the beginning of September, with the publication of Royal Decree 635/2013. The project includes a purchasing procedure for carbon credits from sectors that are not subject to the trade of emission rights, specifically hotels, generated by reduction in their emissions for investment projects.

Although the most interesting thing about it is that it is designed to promote and finance the adoption of energy efficiency measures on the part of Spanish establishments. Despite being welcome, in ITH we believe that it could be better. In this article we analyse the plan’s key points, the strengths and weaknesses, and possible areas for improvement which would turn it into a plan that really drives energy efficiency in the hotel sector.

The PIMASOL plan offers hotels an excellent opportunity to obtain financing that enables them to pay for measures which will have a positive impact on their facilities’ energy efficiency. The plan will spend up to €400 million on financing energy efficiency measures in hotels, of which €200 million comes from the European Investment Bank (EIB), while the rest comes from Santander Bank.

Hotel Fuerte Conil, buque insignia de la cadena en materia de sostebilidad

As part of the “How to promote energy efficiency” campaign, the Spanish Technological Platform for Energy Efficiency and PwC have published a report on how to do this in the Spanish hotel sector, a document whose main purpose is to help identify the challenges and opportunities being faced by the various players who ought to be taking part in the hotel sector’s energy efficiency project.

The tourism sector in Spain is an international benchmark, as the fourth most visited country and the second by related income in the world. Spain received around 57.7 million foreign tourists last year, bringing in income of €55.594 billion, which is a 5.7% year-on-year increase.

In 2012, the tourism sector represented around 10.5 % of the country’s GDP.
