Today, 75% of Europeans live in urban areas and this is expected to rise. Already we are facing an increasing amount of challenges in our cities related to poor air quality, energy poverty, and highly inefficient buildings. The building stock accounts for 49% of Europe’s energy demand and 36% of CO2 emissions at EU level – we need to accelerate the deployment of renewable energy and invest significantly in improving the energy efficiency of our buildings if Europe is to become carbon-neutral.

Against this backdrop, SolarPower Europe has launched the Solar4Buildings campaign –calling for solar on all new and renovated buildings in the EU to help limit climate change.

In the EU, more than 90% of roofs go unused, when they could help mitigate climate change by having solar installed on them. Installing solar on all new buildings and those undergoing renovations makes perfect sense as it could reduce buildings’ CO2 emissions significantly whilst producing clean electricity.

What’s more, Europe’s rooftops have huge solar potential. According to the European Commission’s Joint Research Centre, rooftops in the EU can produce 680 TWh of solar power annually – which is equal to one quarter of the current electricity consumption in the EU.

Solar is one of the most affordable energy sources today. The price of solar panels has dropped by more than 96% since 2000 and is expected to fall even further. By installing solar, European households can also save money on their electricity bills and have access to reliable and clean energy – that makes for a greener future. In Germany, a typical four-person family household with an average annual electricity consumption of 3,600 kWh could save more than €500 each year, if equipped with an average size rooftop system.

Despite these facts, buildings are still regularly being constructed without solar. Now it is time to install solar on all these roofs – on residential, commercial, industrial and public buildings.

SolarPower Europe will present the Solar4Buildings campaign to the new European Commission starting in November and as part of its input to President-elect Ursula von der Leyen’s ‘Green Deal’.

Inerco Ingeniería, Tecnología y Consultoría enters a Strategic Business Alliance Agreement with the energy storage company SaltX Technology – listed on Nasdaq First North Premier –. The partners enter a joint development plan where the first step is to build a pre-commercial pilot in Megawatt scale during 2020.

Inerco has a strong reputation within thermal power generation engineering and technology. The Energy Storage system to be designed will be charged using a non-dispatchable renewable energy or high temperature waste heat. This system will also allow a controlled discharge in periods of high energy demand, as decarbonised high temperature heat (producing steam for electricity generation or heat for direct industrial use).

The goal is to lower the dependency on fossil fuels and increase the flexibility of thermal and renewable power plants. The partners have also agreed to a road map for commercialising the solution. The target markets for the alliance will initially be Spain, Portugal, Central and South America and Mexico. INERCO will be responsible for the development of the first pilot and will also lead the funding of it.

“Inerco finds relevant advantages in nanocoated salts for thermochemical energy storage, which have led us to establish a strong partnership with SaltX. The future of the energy sector undoubtedly implies the use of robust and cost-effective energy storage solutions to be integrated with hybridised conventional and renewable energy sources. SaltX´s nanocoated salts present intrinsic advantages with respect to systems based on other energy storage principles, such as those using molten salts, concrete, or electric batteries, due to their improved energy efficiency, management and safety characteristics. With this technological approach INERCO is convinced about finding competitive solutions for the new decarbonised energy scenario related to both power generation and energy intensive industries”, says Pedro Marín, CEO of Inerco.

Rapid electrification of energy demand and the rise of energy from wind and solar sources will lead to massive growth of the world’s electricity transmission and distribution systems. This is one of the main conclusions of DNV GL’s Energy Transition Outlook 2018: Power Supply and Use report, which provides an outlook of the global energy landscape up to 2050.

The report forecasts continuing rapid electrification, with electricity’s share of the total energy demand expected to more than double to 45% in 2050. This is driven by substantial electrification in the transport, buildings, and manufacturing sectors. In the transport sector, the uptake of private electric vehicles (EVs) will continue to escalate rapidly, with 50% of all new cars sold in 2027 in Europe expected to be EVs.

The surge in global electricity production will be powered by renewable sources accounting for an estimated 80% of global electricity production in 2050. As the costs for wind and solar continue to fall, those two energy sources are set to meet most of the electricity demand, with solar PV delivering 40% of electricity generation and wind energy 29%.

The rapid electrification will lead to major expansion of electricity transmission and distribution systems both in the length and capacity of transmission lines. DNV GL predicts that the total installed power line length and capacity will more than triple by 2050.

The system operators’ tasks will become substantially more complex; yet there may well be less energy flowing across the networks, resulting in fixed costs becoming a greater part of the bill.

High fractions of solar and wind will create a need for increased use of market mechanisms and changes to the electricity market fundamentals in many countries. This requires major regulatory intervention. Market based price signals are crucial to incentivize innovation and develop economically efficient flexibility options.

Despite major expansion of high-capital-cost renewables and electricity networks, energy will become more affordable. It is predicted that the total cost of energy expenditure, as a share of global GDP, will fall from 5.5% to 3.1%, a drop by 44%. Absolute energy expenditure will still grow by 30% over the forecast period, to USD 6 trillion/yr. DNV GL foresees a shift in costs, from operational expenditure, principally fuel, to capital expenditure. From 2030, more capital expenditures will go into electricity grids and wind and solar than into fossil-fuel projects.

Despite the positive outlook on the expansion of renewable energy and the electrification of key sectors, the energy transition will not be fast enough to meet global climate targets. In fact, DNV GL found that the first emission-free year will be 2090, if the energy transition continues at the pace predicted in its report.

Fluctuations in the prices of fossil fuels, the need to address climate change and the growing energy demand, present the current energy model with major challenges. To address them at the same time as achieving high levels of efficiency, new hybrid energy models based on renewable energy are emerging that aim to make a better use of resources and facilitate an energy supply over a longer period. This is the case of CSP-biomass plants designed to produce power using ORC (Organic Rankine Cycle) technology. Innergy is active throughout the entire value chain of an energy project with biomass, providing services that range from the development, production and sale of heat and automation generation equipment to O&M. The company enjoys extensive experience in all types of biomass, industrial biomass boilers and both ORC and steam technology, qualifying it to support biomass for this type of energy solutions.

This type of hybrid energy solution is so interesting because CSP plants need sunlight to shine directly onto their mirrors in order to produce electricity. On cloudy days these plants remain stopped, not generating power and requiring energy from other sources. On the other hand, there is energy generation equipment that uses biomass, a sustainable fuel source that is not subject to weather phenomena, but which, despite existing in large quantities, must be used in a controlled and sustainable manner.

By combining both types, solar power is used on clear days, with the cloudy days covered by energy originating from biomass. This ensures that the plant can operate 365 days a year as it is energy independent from monopolies and large corporations, as well achieving price stability. Read more…

Policy, technological advances and cost reductions have made a cleaner energy mix a reality, and by 2030, Europe is to meet 27% of its total energy demand with renewable energy, and increase its energy efficiency by 30%.

Governments, regions and cities across the globe have committed to reducing carbon emissions in alignment with the COP 21 Paris accord, and many pledges have been made to become solely reliant on renewables by 2040/2050. However, significant transformation and investment across the extended energy value chain, from oil and gas operators, through to power generators, distributors and electricity consumers, needs to take place at a continued rapid pace, to meet policymaker’s targets.


Global Power & Energy Exhibition (GPEX), co-located with Gastech, will take place in Barcelona in September 2018, to provide solutions for businesses adapting to the energy transition. The event will play host to 30,000 business and technical thought-leaders, to address important commercial, regulatory, geopolitical and technical issues impacting the future of the power and energy industry, as well as focus on citizens, as distributed energy generation agents in this new energy model.

Stewart Bundock, Event Director at organiser dmg::events, says: “We are living in truly transformative times, and few industries are facing more change than the global energy sector. A combination of policy and emerging technologies are changing the way that power is produced, distributed and consumed, and revolutionising the landscape over the years and decades ahead. But integration is a vast and complex undertaking that requires cohesion and knowledge sharing.

An innovative, technology-focused exhibition with 200 international exhibitors, will feature four dedicated industry zones with technical seminar theatres, namely Power Generation, Energy Storage, Grid Evolution, Energy Efficiency & Sustainability. The exhibition will feature key sectors and technologies for the energy transition, including electrical mobility, photovoltaic self-consumption, Near Zero consumption and Energy Positive buildings.

The Global Power & Energy Leaders’ Summit – a strategic, c-level conference – will deliver a thought-provoking programme to address the theme of the global energy transition, promoting collaboration among gas, power and energy CEOs and political influencers, as well as new business models linked to energy transition, including energy aggregators and cooperatives. In addition, the Utility CxO Summit will examine how digital technologies are transforming the utility sector, and empowering citizens as new energy producers.

Bundock continues: “Our mission is to gather the people, ideas, technologies and best practices so that policymakers and the energy industry can fulfil their goal of creating and delivering a reliable, low-cost and sustainable energy supply.

Co-located with Gastech Exhibition and Conference in Barcelona, which for over 45 years has been at the forefront of the international gas & LNG market, GPEX aims to bring together the gas, power and energy prosumer communities, who form the central core of the energy transition.

Why Spain?

Spain has historically played a key role in its commitment to renewable and low-carbon energy, and in doing so, establishing a varied and balanced energy mix. Investment in the energy sector has returned, and regional initiatives are in place to reduce carbon emissions dramatically.

GPEX is held in partnership with the Government of Catalonia, who view the energy transition as a key pillar to the economic prosperity of the region. Ms. Assumpta Farran, Director of Catalan Institute of Energy (ICAEN), and Chair of the GPEX Advisory Board, comments:

We are excited to host next year’s GPEX18. It is an historic moment to facilitate switching to a new clean and distributed energy model, taking advantage of the confluence of the application of the internet of things and accelerated through other disruptive technologies, such as electrical vehicles, smart and improved electrical energy storage, blockchain, as well as by the dramatic fall of photovoltaic energy prices. The Agreement for the Energy Transition in Catalonia has already been approved by Catalan Government, to empower citizens to become not only consumers, but also producers. GPEX18 is a great opportunity for ‘Learning by Challenge’, to share experiences, projects and policies with international experts on how to drive and enhance this process.

India can raise its renewable energy use to meet a quarter of the country’s total final energy demand by 2030, according to the findings of a report presented by the International Renewable Energy Agency (IRENA). Renewable energy prospects for India, a study from IRENA’s REmap programme, outlines action areas that can unlock India’s vast renewable energy potential, ensure clean and sustainable energy for generations to come, and enable the country to fulfill its pledges under the Paris Climate Agreement.

Renewable energy prospects for India describes how solar energy will play a vital role representing the second largest source of renewable energy use with 16%, followed by wind at 14%, and hydropower at 7% of the country’s total final renewable energy use by 2030. Biofuels — which can be used across the end demand spectrum, such as for transport, electricity generation and heating — would account for 62%. The country could potentially increase its share of renewable power generation to over one-third by 2030.


With one of the world’s largest and most ambitious renewable energy programmes, India is taking a leading role in the energy transformation both regionally and globally,” said IRENA Director-General Adnan Z. Amin. “India possesses a wealth of renewable resources, particularly for solar and bioenergy development, which can help meet growing energy demand, power economic growth and improve energy access, as well as boost overall energy security.

Increasing renewable energy deployment could save the economy twelve times more than its costs by the year 2030, creating jobs, reducing carbon dioxide emissions, and ensuring cleaner air and water, with savings on health-related costs. Furthermore, the renewable energy technologies identified in the report would lower the demand for coal and oil products between 17% and 23% by 2030, compared to a business as usual scenario.

Meeting India’s electricity demand, which has grown by 10% a year over the past decade, and attaining the country’s economic growth targets will require significant investments in power-generation capacity and related infrastructure, and in transport, buildings and industry sectors, creating important opportunities for renewable energy deployment. IRENA’s report shows that investments in renewable energy capacity must more than double to make the most of India’s potential. Mobilising affordable financing and adapting new business models will be essential to achieve this. India will also need to accelerate the transformation of its power system to integrate higher shares of renewables by strengthening transmission grids, reducing grid losses, and in general improving the resilience of the power system by investing in more flexible system that values demand-response, interconnectors and storage, as well as greater transport and power-sector synergies.

India’s population and economic growth, combined with accelerating urbanisation, is expected to increase the number of people living in cities and towns from approximately 435 million in 2015 to 600 million by 2030. In addition, estimates suggest that 80 million households — roughly 300 million people — have limited or no access to electricity. Renewables can improve energy access for poor communities and bolster energy security through diversified, and largely indigenous, sources of supply.

Renewable energy prospects: India REmap analysis is part of IRENA’s renewable energy roadmap programme, REmap, which determines the potential for countries, regions and the world to scale up renewables to ensure an affordable and sustainable energy future. The roadmap focuses on renewable power technologies and technology options in heating, cooling and transport. The India study is the latest in the series of country-level REmap analyses, which includes countries such as China, Germany, Dominican Republic, Indonesia, Mexico, Russia and the United States.

Forecasts for the Kingdom of Morocco indicate that the country’s energy demand will rise continuously in the coming years. The country has abundant renewable energy resources – including solar, wind and hydropower – and has set a 52% renewable target by 2030 while reducing its current dependency on imported fossil fuels. The government is focused on developing its electrical infrastructure to integrate renewable energy, with targets to generate more power from wind and other renewable energy sources.

ABB is working with Energie Eolienne du Maroc, one of the leaders in Morocco’s energy sector, to build a new hybrid substation in southern Morocco that will connect to the country’s national grid. It will be the first hybrid substation in Morocco and is being designed to withstand the challenging weather conditions of the desert and the marine air conditions. During the 22nd United Nations Framework Convention on Climate Change event, hosted in Marrakech at the end of 2016, Nareva’s new wind farm received a COP 22 label.


The hybrid substation will have a capacity of 225/33 kilovolts (kV) and will be flexible and scalable, with the ability to be upgraded up to 400 kV or the wind farm upgraded to 300 MW. Nareva is involved in several wind farm developments across Morocco.

The company was seeking strong customer support from its potential supplier. ABB teams from Spain, Morocco, Italy, Turkey, Switzerland and Sweden worked together to provide technical seminars, and various lifecycle cost analytics. The hybrid substation will include the latest ABB technology of PASS, ZS2 MV switchgear, 150 MW of power transformers, instrument transformers, surge arresters, substation automation system as well as protection and control. The new substation enhances ABB presence in Africa and ABB Power Grid’s goal to enable a stronger, smarter and greener grid for its customers.

In July 2014, the Madrid Health Service announced a public tender for a Mixed-Purpose Contract for Supplies and Works to construct and manage a natural gas-fired thermal plant at the Hospital Universitario La Paz. The 15-year contract had a tender budget of almost €45m (ex. VAT) to supply power to cover the hospital complex’s energy demand for heating, DHW and steam. Four proposals were submitted, with the contract finally being awarded to the joint venture comprising Gas Natural Servicios SDG and Veolia Servicios Lecam.

The Hospital Universitario La Paz is one of the largest hospitals in terms of importance in the Autonomous Community of Madrid and an essential part of the public healthcare system. Consisting of four buildings that house the General Hospital, Maternity Hospital, Children’s Hospital and Trauma Centre, the complex covers a surface area of 180,000 m2 and has a total of 1,328 beds.


Due to age (some 50 years) and the degree of wear and tear of its thermal installations, the Hospital Universitario La Paz was facing high energy and O&M costs in addition to: the risk of a lack of supply, with the resultant risk to the health and wellbeing of patients and workers., high environmental impact, due to the use of diesel. and an inability to handle increases in demand.

Half of all EU citizens could be producing their own electricity by 2050, and meeting 45% of the EU’s energy demand. The European energy market is switching from fossil fuels and nuclear to renewable energy, but it’s also shifting from a centralised market dominated by large utilities to one in which people produce their own energy and help to manage demand. Without these “energy citizens”, the transition to a 100% renewable energy system won’t be possible.

Some of the effects of this transformation have been calculated in a report carried out by the European Renewable Energies Federation, Friends of the Earth, Greenpeace and the European Federation of Renewable Energy Cooperatives. The study, “The Potential of Energy Citizens in the European Union”, considers production by households, collectives, micro and small enterprises, and public entities. The technologies assessed are wind farms, solar panels, stationary batteries, electric boilers and electric vehicles.

The report estimates the number of energy citizens that exist today, as well as how many could exist by 2030 and by 2050, in individual member states and in the EU as a whole. It shows that over 264 million European Union citizens, half of the population, could be producing their own electricity by 2050. These energy citizens could be producing 611 TWh of electricity by 2030 and 1,557 TWh by 2050. Therefore, by 2030, energy citizens could be delivering 19% of the EU’s electricity demand, and 45% by 2050. This is a significant contribution to achieving the EU’s 2030 renewable energy target and moving towards a 100% renewable energy system.

From a country perspective, Germany, France and the UK have the largest potential in terms of energy generated. Sweden would lead in the proportion of citizens involved in electricity production (79 % of the population). Latvia has the highest potential for generation capacity as citizens could be meeting 83 % of the country’s electricity demand in 2050.

In 2050, collective projects and co-operatives could contribute 37% of the electricity produced by energy citizens, while microand small businesses could contribute 39%, households 23% and public entities 1%.

The report also looks at what energy citizens can contribute in demand response, by use of stationary batteries, electric vehicles and smart boilers that use energy when it’s plentiful, not when demand peaks. It shows that in 2050, seven in ten European citizens could be engaged in demand response.

Energy citizens could unlock 1,494 GWh of electric storage by 2030 and 10,490 GWh by 2050. This storage would significantly reduce system peaks and ensure clean and affordable back-up capacity. The results show that energy citizens are capable of delivering a large share of the renewable energy and demand-side flexibility needed to decarbonise Europe’s energy system

Yet, energy citizens face significant legal obstacles to making their own electricity. Throughout the European Union there are explicit legal restrictions, disproportionate administrative and planning procedures and punitive tariffs that prevent citizens from driving a renewable energy transition. With the right EU legal framework, energy citizens could flourish and deliver a significant share of Europe’s renewable energy and provide important flexibility to the energy system through demand response.

In its latest report, The Economics of Commercial Energy Storage in the U.S., GTM Research analyzed rate structures across 51 utilities to determine the opportunity for demand charge management for commercial energy storage customers. According to the report, commercial energy storage economics are attractive today in seven U.S. states. And that number is expected to grow to 19 states by 2021.

U.S. commercial energy storage deployments grew fourteenfold between 2013 and 2015, making it the fastest-expanding segment of the U.S. energy storage market. While that growth rate is very high, it’s important to note that the commercial storage market is expanding from a small base. Adoption today is limited to a handful of states with local incentives and high retail electricity rates. However, as storage costs continue to decline, more markets will emerge as offering attractive economics.

The report models the internal rate of return (IRR) for 1-hour and 2-hour storage systems for both the small/medium-sized and large commercial customer segments. It found that demand-charge rates of at least $15 per kilowatt per month are necessary to achieve favorable economics for energy storage today. By 2021, commercial storage economics will be favorable for certain utility tariffs with demand charges as low as $11 per kilowatt per month.

Large commercial customers in 17 U.S. states will have an internal rate of return of 5 percent or higher, which GTM Research identifies as “in the money.” For small/medium-sized systems, 14 states will be economically attractive. Taken together, there will be 19 unique states primed for commercial storage adoption in 2021. Under GTM Research’s aggressive cost reduction case, storage costs are forecasted to fall 15 percent annually over the next five years. In this scenario, there could be as many as 26 states where commercial storage is economically attractive.

Energy storage can provide multiple benefits across the grid. However, most of the commercial storage deployed today is used to provide demand-charge-related bill savings.
