energy bill

Egypt has the potential to generate up to 53 per cent of its electricity from renewable sources by 2030, according to a report by the International Renewable Energy Agency (IRENA). The Renewable Energy Outlook: Egypt report, finds that pursuing higher shares of renewable energy could reduce the country’s energy bill by up to USD 900 million annually in 2030.

Renewables could cost-effectively provide up to a quarter of Egypt’s total final energy supply in 2030, per the analysis. Achieving the higher targets would, however, require investment in renewables to grow from USD 2.5 billion per year based on today’s policies to USD 6.5 billion per year. Under current plans, Egypt aims to source 20 per cent of its electricity from renewables by 2022, rising to 42 per cent by 2035. Total installed capacity of renewables in the country today amounts to 3.7 GW.

Egypt can draw on an abundance of renewable energy resources to achieve higher shares of hydropower, wind, solar and biomass. To capitalise on this, the report suggests that national policy makers may benefit from periodically re-evaluating the long-term energy strategy to reflect rapid advances in renewable energy technology and falling renewable power generation costs.

Building on these achievements, Egypt has the opportunity to further raise its ambition which entails substantially increased investments. Attracting these investments requires stable policy frameworks and a streamlined regulatory environment that provides clarity and certainty for investors. Investments in renewable energy not only help to meet rising energy demand but they can also contribute to fostering economic growth, creating employment and developing local manufacturing.

The report was prepared by IRENA in close collaboration with Egypt’s Ministry of Electricity and Renewable Energy, and the New and Renewable Energy Authority.

Dubai Airports will use Siemens Building Technologies data analytics and smart building technology to guarantee annual energy savings of almost 20 percent per year at Dubai Airports’ facilities, by implementing energy efficiency measures at Terminal 1, Terminal 2, Terminal 3 and Concourse B at Dubai International (DXB). Focusing on air and water systems, the seven-year project is expected to reduce CO2 emissions by approximately 25,000 tons, with annual electricity savings of approximately 50 gigawatt hours (GWH), and water savings of around 21 million gallons. The initiative is part of Dubai Airports’ comprehensive energy-saving strategy and program designed to limit the environmental footprint at both of its airports.

A tailor-made energy optimization solution has been designed for the project by Siemens, comprising a range of physical and digital technologies including variable frequency drives, panels, sensors, intelligent controls, energy metering and efficient water fixtures. These will be deployed to the air and water systems to optimize the air-handling units, chilled water system, fresh air plant and the secondary fresh air, supply and exhaust fan systems.

Siemens will be responsible for the project’s design, supply, installation, commissioning and maintenance, and also the measurement, verification and guarantee of energy savings for seven years. The customer is Etihad ESCO (Energy Service Company), a venture by Dubai Electricity and Water Authority launched in 2013 to promote a performance contracting market for energy service companies. Etihad ESCO aims to jumpstart the creation of viable performance contracting market for energy service companies by executing building retrofits, increasing penetration of district cooling, building capacity of local ESCOs for private sector and facilitating access to project finance.

In October 2017, Etihad ESCO signed an agreement with Dubai Airports for the retrofitting of Terminals 1, 2, 3 and Concourse B of Dubai International Airport.

Siemens is a pioneer in digitalized buildings in the Middle East, having implemented smart building technology in key landmarks including Abu Dhabi’s Sheikh Zayed Grand Mosque, Dubai’s Atlantis Hotel and 3D-printed Office of the Future, and the recently-launched Dubai Opera. In addition, Siemens Building Technologies provides tailor-made solutions for airports worldwide, for example to support the modernization of La Guardia, New York’s international airport through integrated building automation and fire safety.

HVAC units are big consumers of energy in the majority of installations in a range of sectors. They can account for 60% of the electricity bill in tertiary sector buildings such as hotels, hospitals, shopping centres, industrial and office blocks. The way forward to finding solutions that achieve energy savings in this field is based on access to information. As a result, Indoorclima is developing the Climate management Big Data, offering vital information on the operation of chiller and rooftop units from manufacturers worldwide. Having knowledge of their actual operation in a wealth of situations (both those inherent to the units and those relating to the installation or location) is providing the keys to developing the necessary algorithms to be able to parameterise each installation in terms of optimal performance and thereby reduce energy consumption from 20% to 50% depending on the installation.

HVAC installations have a low level of energy management. One major issue is the lack of the control over large output units that are usually located in regions with difficult access, and the preventative maintenance itself that is very basic, generally reduced to the minimum regulatory requirement. As a reference, of the total sales of HVAC units in 2012, only 15% corresponded to regulation and control systems. And this, in sectors where HVAC units consume more than 3,000,000 kWh/year, representing disproportionate and unnecessary energy costs.

And this has provided the basis for the work of Indoorclima in its search for a solution whose main aim is to save energy in HVAC installations. Read more…

SediREC from Sedical is designed for the energy and volumetric management of water in heated swimming pools providing very high levels of energy efficiency. This system, able to manage one or several pools in the same sports centre all day long, has already been installed in different facilities, achieving excellent results that are even better than the forecasts made prior to installation. One such facility is the Altzate municipal sports centre in Lezo (Gipuzkoa), where the SediREC system has been in operation for nearly two years, achieving monthly savings on the energy bill of more than €2,000/month.

Inaugurated in 2001, the Altzate sports complex houses two swimming pools: the main pool (large) and a small pool which is used for aqua-gym, hydrotherapy and children’s swimming lessons. The total volume of both pools is 571 m3. Prior to the installation of the SediREC system in May 2013, management of the pools’ renovation water, essential to guarantee the required water quality, represented a cost of €3.76/m3, generating a monthly expenditure of €2,512. Table 1 provides an analysis of the operating situation of these swimming pools before installation of the SediREC system.

The custom of cleaning the filters for 5 minutes every 3 days for the large pool and 5 minutes every 2 days for the small pool, involved extracting a considerable volume of water from the filter with the associated energy loss being compensated for by means of boilers. Read more…

No-one can deny the fact that CHP is one of the most efficient ways of generating power. To name but a few of its advantages, it helps reduce natural gas consumption and the energy bill; by being generating at the points of consumption there are no losses from its distribution; it strengthens the security of the energy supply; it increases the competitiveness of those industries that use it; it creates jobs and contributes to the industrialisation of the country. And these are not its only benefits. So why are we letting it die out?

There are many reasons to defend CHP as a technology that we cannot do without as it generates electrical energy and heat. The above benefits are the most obvious; they are those that would feature in any efficient energy generation manual. But they are not alone.

In 1990, the Member States of the European Union undertook that, by 2020, they would reduce greenhouse gas emissions by 20%; increase the presence of renewables by 20%; and bring down the consumption of energy by 20% through increased energy efficiency. The majority of the States are, to a lesser or greater extent, complying with the first two objectives. However, both globally and individually, we are a long way from achieving the 20% energy saving target. Read more…

The Hotel TRH Ciudad de Baeza has undertaken the remodelling of its fan-coil heating and DHW production system by installing high performance condensing boilers from the manufacturer Ygnis. The incorporation of these boilers has a very positive impact on the performance of the heating and DHW production units, as demonstrated by the consumption results obtained after two full seasons in operation. As illustrated below, the reduction in consumption brings with it a significant reduction in the hotel’s energy bill. The economic impact is such that in the space of 1.5 years, the installation investment has been paid for, taking the six-month heating period as the basis for calculating the amortisation.

The hotel had two 4,000-litre tanks for DHW, heated by four electric resistance units of 18 kW each with a total output of 72 kW. These tanks used to supply the fan-coils circuit for heating and the DHW circuit. The existing installation was located in a basement, with little available space and no flue gas outlet, thereby preventing the installation of any type of boiler irrespective of the fuel used, unless a completely new boiler room was built.

The possibility of choosing renewable sources was dismissed because the peculiarities of the TRH hotel, an ancient 16th Century Carmelite convent next-door to the Church of the Hospital de la Concepción. Its location in the historic centre of Baeza, a UNESCO World Heritage city, made any structural reform to the building completely unfeasible. The lack of flat roofs and terraces meant that it was impossible to use the rooftop for the installation of solar panels. Nor was the option of using biomass viable due to the lack of space required for its management. Read more…

On 26th June the Platform for Distributed Generation & Energy Self-Consumption held a press conference in Madrid, in which it explained its point of view on self-consumption with net balance regulation, and the need for regulation that really benefits not only consumers, enabling them to save on their energy bill, but also industries, enabling them to improve competitivity.


According to the Platform, the development of a distributed generating market, focusing on saving and efficiency, would create employment, promote technological development, help to reach environmental goals, avoid the need for energy imports and allow a good section of the renewables sector to survive, particularly that part of it involved with PV and mini-wind energies.
