A Turboden 4 MW heat recovery ORC system will be installed in the 80 MW power station of Gibraltar, designed and supplied by Bouygues Energies & Services. This solution improves the power plant efficiency and reduces the overall life-cycle costs.

The Turboden 40 HRS ORC unit exploits the heat of exhaust gases coming from three MAN 14V51/60G gas engines (14.3 MW each), to generate 4 MW of gross electric power, achieving an overall combined cycle efficiency of 52%. Turboden will supply the ORC system including the three primary heat recovery exchangers for the direct heat transfer between the engines exhaust fumes and the ORC working fluid.

The ORC system start-up is expected in the first quarter of 2017. Once in operation, the heat recovery plant will lead to an annual saving of 42.000 Barrel of Oil Equivalent and will avoid the emission of 12.000 tons of CO2 equivalent each year.

Turboden has been developing direct heat exchange solutions for medium temperature hot gases (e.g. 600 °C) since 2009, when the first 500 kW direct exchange ORC unit was installed downstream a 7 MW diesel engine. In addition to the first unit, Turboden has supplied other 4 ORC units with direct exchange. The direct exchange solution allows avoiding the presence of intermediate circuits, leading to improved performances, lower investment cost and simpler schemes.

These applications represent an important technological innovation and provide several benefits and advantages compared to other solutions, as well as enhancing environmental sustainability, emissions reduction, industrial process efficiency and business performance. Turboden is committed to successfully deliver its ORC solutions worldwide, providing maximum quality service from commissioning to aftersales to achieve the expected performance results throughout the life of the plant” says Roberto Bini, Turboden Managing Director and R&D Manager.

In heat recovery applications, Turboden ORC units can be employed in combined cycles with reciprocating engines, with a net output increase of 8-12%, and with gas turbines, with a net output increase up to 25-45%, depending on the primary mover efficiency and on the fuel used. Turboden ORC modules can find an efficient use in these dry combined cycle projects, thanks to the good electrical efficiencies, minimum requests of operation and maintenance and simplicity of all start and stop procedures, which allow system management even by a non-licensed technician and permit operations in remote locations, with lack of water and extreme climates.

For medium temperature heat recovery (e.g. 300 °C), the ORC technology – compared to the traditional steam based solutions- leads to a relevant improvement of the net power output leveraging the perfect match between the heat source and the working fluid selected. Additionally, thanks to the characteristic of an organic compound as working fluid, the Direct Exchange ORC solution puts together the effectiveness of once-through type evaporators (high performances, fast response, low cost) to the ease of operation of the thermal media (no issue of corrosion, erosion, scaling, etc).

Turboden 35 years’ experience in the construction of ORC turbogenerators made possible the design, implementation and delivery of more than 300 power plants, with an overall power output of about 430 MWe, of which 10 units recover waste heat from internal combustion engines and from gas turbines, with a total power capacity of 13.5 MWe. The power of Turboden ORC turbogenerators in this application typically ranges between 500 kW and 15 MW electric.

    On 23 September, Mexico’s President, Enrique Peña Nieto, inaugurated Phase I of the Los Azufres III geothermal power plant in Michoacán. Forming part of the Los Azufres Geothermal Field, operated by the Federal Electricity Commission (CFE), falling within the National Infrastructure Plan 2014-2018 and commissioned in February 2015, this complex adds some 50 MW of clean energy to Mexico’s electrical system, generating net earnings for the CFE of 41 million pesos per year.

    The inaugural event was well-represented by the government, as apart from the President himself, it was attended by Enrique Ochoa Meza, Managing Director of the CFE; Francisco Medina Chávez, Managing Director of Grupo FAME; Salvador Jara Guerrero, Governor of Michoacán; Jaime Esparza Cortina, Secretary of the Government of Michoacán; Pedro Joaquín Coldwell, Secretary for Energy; Rafael Pacchiano Alamán, Secretary for the Environment and Natural Resources; Gerardo Ruiz Esparza, Secretary for Communications and Transportation; the mayoress of Zinapécuaro, María del Refugio Silva Durán, in addition to state, federal and municipal civil servants, senators and military commanders.

    With an investment of 968 million pesos, the first phase of Azufres III has a 53 MW capacity and, as already mentioned, it will generate clean energy at national level equivalent to supplying electricity to a population of some 195,000 inhabitants while occupying a surface area of just 1.5 hectares. Thanks to its clean technology, it will avoid the emission into the atmosphere of more than 177,500 t/year of CO2.

    The new plant will increase the total installed capacity of the Los Azufres Geothermal Field by 17%, going from 192 MW to 225 MW, thereby adding around 404 GWh of clean energy to Mexico’s electrical system. In other words, enough energy to service a population of 800,000 inhabitants. The CFE is planning the construction of another geothermal plant in this same area, namely Los Azufres III Phase II that will have a capacity of 25 MW. The project conditions were published on 8 July, the deadline for submission of proposals ends on 30 October and adjudication will take place on 25 November this year. The CFE is currently promoting the implementation of 14 renewable energy generation projects, six of which are geothermal, with an approximate investment of US$4.4Bn.

    Mexico is the first country in Latin America and the fourth largest worldwide in terms of total installed geothermal energy generation capacity after the USA, the Philippines and Indonesia. Specifically, in the state of Michoacán, 100% of the electrical power produced comes from renewable sources with 90% from hydroelectric and 10% from the Los Azufres Geothermal Field, accounting for 25% of Mexico’s installed geothermal capacity.

    The PV Mobile Lab, the mobile testing solution of Enertis has carried out on-site testing of solar projects totaling 300 MW of installed capacity in the first six months of the year. The projects are distributed across more than 20 plants and about 2,000 modules analyzed. This figure contributes towards more than 6,000 inspected panels since the PV Mobile Lab’s launch in 2013.

    The work performed by the PV Mobile Lab has allowed the technical assessment of PV modules throughout the sale process of large solar installations, to verify and validate the quality of the modules prior to shipment of supplies from factories. Furthermore, it helps detect and diagnose degradation problems with the modules after the first months of operation. For example, thanks to PV Mobile Lab, Enertis has been able to analyze and diagnose cases of Potential Induced Degradation (PID) at several photovoltaic plants in France and England, estimating with high accuracy the degree of evolution of the issue. In addition, this tool has been used to evaluate, thanks to its Class A+A+A+ solar simulator (IEC 60904), the incidence of different visual defects (“snail trails”, yellowing, etc.) in the capacity of the photovoltaic modules installed to produce energy.

    Quality control on-site

    In the first six months of 2015, the PV Mobile Lab has conducted quality controls and tests of projects for most of the major investors, developers and builders of photovoltaic solar plants worldwide such as SunEdison, Lightsource RE, Conergy and Next Energy Capital.

    The PV Mobile Lab’s flexibility accompanies Enertis in its international expansion. Since its launch the PV Mobile Lab has been operating in many European countries such as Spain, France, Italy, Germany, the Netherlands and the United Kingdom, in addition to the United States, where Enertis also possesses one mobile laboratory unit.

    Furthermore, Enertis is currently developing additional units which, with strategic partners, will allow the company to provide similar on-site services in several important markets such as Japan, China, Brazil, Chile and India.

    Enertis helps developers, engineering firms and financial institutions, among other players of this industry, to ensure the profitability of investments in photovoltaic projects, checking the status of the modules and their ability to ensure electricity production during their lifespan, and minimizing the risk of loss of productivity resulting from failure.

    PV Mobile Lab

    The PV Mobile Lab, designed and developed by Enertis, is the first mobile unit planned to perform on-site quality control of the significant component of photovoltaic plants, the solar module, avoiding its transport to conventional fixed laboratories and significantly reducing the period of time during which the panels are uninstalled to undergo technical inspections and performance tests. This is an important tool when accepting large batches of modules and inspecting for impairments, among other applications, thanks to the measurement of maximum power of the modules under Standard Test Conditions (STC, 25 °C, spectrum AM1.5G and 1,000 W/m2 irradiance), with a low margin of uncertainty.

    The laboratory is equipped with a class A+A+A+ solar simulator tunnel type and is able to control environmental conditions. Those are very important features, which ensure that results that results from the measurements obtained have a small margin of error.

    The PV Mobile Lab equipment allows performing the following non-destructive testing on the PV modules on-site: Electroluminescence, Thermographic Inspection, Visual Inspection, Maximum Power Measurement and Electrical Insulation. The last three tests are performed following the Conditions Measure standard set in the IEC 61215:2005, whose implementation is accredited according to international standards ISO/IEC 17025: 2005.

    In addition to the photovoltaic modules testing, the PV Mobile Lab comes with other necessary equipment to conduct a comprehensive diagnosis of the status of the plant both before and during its implementation.

    The PV Mobile Lab has been funded by the Comunidad de Madrid, through aid managed by Madrid Network, an organization created to promote regional industry R&D promoted by the Consejería de Economía, Empleo y Hacienda.

    Saudi Arabia represents one of Himoinsa’s main Middle East markets. According to recent reports published by TechSci Research, the diesel generator set market in Saudi Arabia will reach $709 million by 2020. In addition to these positive market forecasts are the recent sales figures for the company in Saudi Arabia. In the past 19 months, Himoinsa generator sets represent a 7% share of the total market for generator sets in Saudi Arabia.

    Construction on the bridge linking Bahrain with Saudi Arabia, as well as the construction of the Makkah-Medina high speed railway, have employed Himoinsa generator sets. Most of the generators sold in Saudi Arabia have been distributed to rental companies, as well as lighting towers, increasingly requested by rental firms. In the past two years, Himoinsa Middle East has sold more than 600 lighting towers in the region; 30% of them in Saudi Arabia.

    Himoinsa works in the region through its distributor FAMCO, which began to made significant inroads into the Saudi Arabia market in 2013. “In the past 19 months, 33% of sales of Himoinsa generator sets in the Middle East correspond to Saudi Arabia”, says Guillermo Elum, Sales and Marketing Director in the Middle East, Africa, Latin America and Europe, who describes Saudi Arabia as “one of our major markets in the region.” While the construction sector has been one of the most important for Himoinsa, the company is now focusing its attention on the telecommunications, residential and industrial sectors. Areas for which the company offers innovative energy solutions.

    The figures speak for themselves. By 2020 it is expected that 429 billion kW will be generated in Saudi Arabia. During 2014, the residential sector alone represented 30% of the market of diesel generator sets in Saudi Arabia, according to TechSci Research, in its report which highlights the North, Centre and West areas of Saudi Arabia as those with the greatest demand for generator sets. These areas alone represented 56% of the diesel generators market in Saudi Arabia in 2014.

    Himoinsa Executive Director, Lydia Gracia, stated that the key to the success of the company in Saudi Arabia lies in the flexibility of the company when it comes to adapting the product to the needs of a special market, among others, due to its extreme weather conditions. “We are prepared to work in extreme conditions, withstanding temperatures of 50 ºC. Desert areas require special working conditions, as at certain times of the day it can be humid but always dusty, factors that could damage the genset’s filters and therefore affect its operation.

    Himoinsa generator sets headed for desert climates are designed with tropicalized radiators with double varnish and anti-condensation resistance. The alternator air filters are specially treated to prevent dust from entering and to ensure uninterrupted power supply.
