Solar storage avoid grid expansion for electric cars

Solar storage avoid grid expansion for electric cars

February 4, 2019: According to a study by the TU Braunschweig (Germany), solar power systems in combination with battery storage systems can provide full coverage with charging points in local grids without the distribution grids having to be expanded expensively.
Through the use of solar power systems with battery storage, according to the study, today's power distribution grids in districts with private one- and two-family homes can supply more than every other connected household with its own 11 kW charging station for electric cars (up to 60 percent). Decentralized solar energy storage thus doubles the charging capacity compared to a traditional low-voltage distribution grid. And the majority of the newly installed solar power systems are now installed together with a battery storage system, according to the German Federal Solar Industry Association. In the event of a modernization of the regulatory framework for the use of the entire flexibility potential of decentralized battery storage, it would even be possible to achieve a complete supply of e-car charging points in the local suburban and village grids.

German government devotes €1bn to battery cell production

November 14, 2018: The German Minister of Economics, Peter Altmaier, unveiled the first details of his plans to help Europe – via Germany – construct gigawatt-sized battery cell production capacity. Mr. Altmaier said the German government is intending to support consortia willing to build big battery cell production lines in Germany with a budget of €1 billion. He is confident that by the end of next year, a first consortium to produce battery cells would be set up in Germany.

The minister also said he is in talks with potential partners from France, Austria and Poland. “We have to produce state-of-the-art batteries in Europe,” he said, referring to competition in Asia and the U.S. It is clear Europe will not produce the cheapest batteries, he added, but it should make the most sustainable.

According to Maros Šefčovič, EU Commissioner for the Energy Union, the battery cell market in 2030 will have a global volume of €600-800 billion and Germany will play a key role in the development of battery cell production.

The project marks Edison's first solar-plus-storage pilot in Italy

Edison connects large-scale storage system at PV plant in southern Italy

November 14, 2018: Italian power provider Edison has finalized its first large-scale storage project linked to a PV power station, in southern Italy. The system can provide grid services such as primary and secondary frequency regulation and tertiary and voltage regulation. The company said a 500 kW/822 kWh storage system of 108 lithium ion battery modules has been deployed at its 3 MW solar plant in Altomonte, in the southern Italian region of Calabria. The system is the next biggest large-scale storage project operational in Italy, after those developed by grid operator Terna, which launched a program to deploy around 40 MW of storage capacity a few years ago.

According to Edison, the project will help compensate for the variability of renewables while enabling the testing of such storage systems for other grid services. The company says the storage system can be managed to minimize deviations between expected and real production, through software which considers weather forecasts.

Global cumulative storage deployments (source: BNEF) / Click to enlarge


BNEF has significantly increased its forecast for global deployment of behind-the-meter and grid-scale batteries over coming decades

November 6, 2018: The tumbling cost of batteries is set to drive a boom in the installation of energy storage systems around the world in the years from now to 2040, according to the latest annual forecast from research company BloombergNEF (BNEF).

The global energy storage market (excluding pumped hydro) will grow to a cumulative 942GW/2,857GWh by 2040, attracting $620 billion in investment over the next 22 years. Cheap batteries mean that wind and solar will increasingly be able to run when the wind isn’t blowing and the sun isn’t shining. BNEF’s latest Long-Term Energy Storage Outlook sees the capital cost of a utility-scale lithium-ion battery storage system sliding another 52% between 2018 and 2030, on top of the steep declines seen earlier this decade. This will transform the economic case for batteries in both the vehicle and the electricity sector. Yayoi Sekine, energy storage analyst for BloombergNEF and co-author of the report, said: “We have become much more bullish about storage deployments since our last forecast a year ago. This is partly due to faster-than-expected falls in storage system costs, and partly to a greater focus on two emerging applications for the technology – electric vehicle charging, and energy access in remote regions.”

PricewaterhouseCoopers: combination of PV and storage will be the most lucrative option as early as 2021

November 2, 2018: According to the current PwC analysis "Energyfacts: Old Photovoltaic Plants - End of Support  in Sight", it will be more attractive for system operators who no longer receive EEG funding to use the solar power in their own homes than to sell it on the energy exchange. Owners of typical roof systems on detached houses, where the support ends in 2021, could only generate an average of 163 euros per year when selling electricity on the energy exchange. At the same time, they could save 533 euros per year if they use the electricity themselves. The financial benefit is even more pronounced when the photovoltaic system is combined with a storage system.

"Thanks to sinking storage prices, self-consumption with the help of a storage system, according to our calculations for 2021 onwards, is the most lucrative option for owners of typically privately used systems," says Norbert Schwieters, Head of Energy Management at PwC. In the following years, this option should be even more lucrative, because the storage prices are likely to continue to fall sharply after 2021. PwC estimates that prices will halve by 2025 compared to today.

Portuguese utility EDP invests in energy storage in Romania

EDP Renováveis has switched on a large-scale storage system in

Portuguese utility EDP invests in energy storage in Romania

October 1, 2018: In a separate statement, EDP revealed that its renewable energy unit, EDP Renováveis (EDPR) has switched on a large-scale storage system, coupled with its Cobadin Wind Farm, located in the Romanian eastern region of Constanța. The company said its “Stocare Project” is the first of its kind in Romania, where it currently operates more than 500 MW of installed wind capacity. “This type of power storage facility could be a turning point in the energy market in the coming years, as it will convert renewable energy such as wind or solar photovoltaic into constant energy sources and therefore more efficient and predictable,” the company said, without providing further technical or financial details on the project.
EDP has recently expanded its renewable energy business, traditionally dominated by wind, into solar and hybrid wind-solar projects. In August, it also adopted a new blockchain technology, developed by Austrian company, Riddle&Code, to measure how much power owners of distributed generation PV systems in Brazil self-consume or inject into the grid under net metering.

Heavy demand at the commercial storage providers Tesvolt GmbH
and Alpha ESS at the ees Europe 2018 in Munich

Great demand for commercial storage - driven by the expiry of the EEG

September 27, 2018: Commercial storage is an interesting solution for energy-intensive, commercial enterprises that draw their electricity from their own photovoltaic system, but have so far - often for cost reasons - not installed a suitable battery storage. "Rising electricity prices and the phasing out of the EEG for older plants are pushing more and more companies to operate their commercial facilities with self-sufficient energy," explains Hermann Schmees, Managing Director of specialist and wholesaler Redpoint New Energy based in Werlte. "Among other things, this great demand has prompted us to include larger commercial storage for the retrofitting of existing plants in our product portfolio." Redpoint relies on the industrial storage of Alpha ESS. According to the company, the modular AC industrial storage Alpha ESS Storion-T30 is equipped with lithium-iron-phosphate battery modules and has a loading and unloading capacity of 30 kilowatts, which can be extended by a capacity of approx. 23 to 70 kilowatt hours.

By the year 2020, according to Macrom, a doubling of the current
market volume for battery home storage can be expected.

Germany the world's largest market for battery home storage

September 25, 2018: For the manufacturers of battery home storage, Europe was the most important sales region worldwide in 2017; Within two years, the sales of systems have almost tripled, according to an analysis by Macrom.Germany is, according to the analysis, the largest domestic market for home storage in Europe as well as worldwide. However, the most dynamic growth - in 2017 compared to 2016 with a plus of 70 percent - is in Italy. Macrom has also identified significant differences in other parameters. On the one hand, statutory regulations differ, especially with battery inverters. But there are also national differences in the storage capacities demanded, which are mainly related to the sizes of private photovoltaic systems that are used in the respective country.For the coming years, Macrom expects the battery home storage market to continue on its growth path. Due to the increasing number of storage units that are sold with new photovoltaic systems and the increasing retrofitting of existing systems, a further doubling of the current market volume is expected by the year 2020.

Italy extends tax incentives to home storage for private photovoltaic systems

Italy extends tax incentives to home storage for private photovoltaic systems

September 21, 2018: The tax incentives for the installation of photovoltaic systems on residential buildings in Italy in connection with sustainable new construction and refurbishment will be extended to small storage systems. According to a recent document of the Italian tax authority, a deduction of income tax (IRPEF) of a maximum of 50 percent of the costs incurred up to a maximum of 96,000 euros can also be applied to the purchase of a storage system, if this is related to a new or existing photovoltaic system being installed.
Income tax deduction has been one of the main driving forces behind the development of the market for private photovoltaic roof systems in Italy in recent years. Now it could push the photovoltaic home storage business, especially as many rooftop installations have been installed over the past decade.
In June 2017, the Italian energy agency GSE published new technical regulations for the integration of storage systems in combination with photovoltaic and renewable power plants. In addition, the Energy Ministry of Lombardy, Italy's most industrialized region, has so far distributed around seven million euros to promote storage projects up to 20 kilowatts in combination with photovoltaic systems.

Green Hydrogen - potential for gigawatt industry

September 18, 2018: The generation of green hydrogen from photovoltaic and wind power has enormous potential for the future and is increasingly becoming a core technology of the energy transition, as it can store, reverse-cycle or convert the volatile wind and solar power seasonally into power and chemical raw materials. For Germany alone, an installed water electrolysis capacity in the three-digit gigawatt range is expected by 2050, provided that the German government reaches its climate protection goals, the Fraunhofer Institute for Solar Energy Systems ISE explains. On behalf of the Ministry of Transport, the Freiburg scientists, together with the Fraunhofer Institute for Production Technology and Automation IPA and the consulting firm E4tech, have developed a roadmap for the establishment of water electrolysis in Germany.

In their study "Industrialization of Water Electrolysis in Germany: Chances and Challenges for Sustainable Hydrogen for Transport, Electricity and Heat", they show how industrial manufacturing capacities could be built up in Germany in the coming years. The result was an expansion corridor between more than 100 and well over 200 gigawatts of installed electrolysis capacity in Germany by the middle of the century, according to the researchers.

WBS 500 takes over power supply and stabilizes grid frequency

WEMAG commenced operation of first multi-purpose battery station

September 17, 2018: The Schwerin energy provider WEMAG officially launched its battery storage station WBS 500 in Neustadt-Glewe in Mecklenburg this Monday. With a capacity of 750 kilowatts and a storage capacity of 925 kilowatt hours, this prototype marks a new generation of decentralized battery storage.

The small stations compared to battery power plants will in the future alone or jointly take over different tasks of the energy supply, improve grid stability and enable the integration of renewable energies or charging infrastructure for electromobility. To do this, the WBS 500 will be bundled with the existing Schweriner WEMAG battery storage in a virtual power plant. Planned is the construction of additional storage for regional energy suppliers.

Since 2014, WEMAG has been operating a lithium-ion battery storage facility in Schwerin, whose capacity was doubled in June 2017 from five to ten megawatts. The station in Neustadt-Glewe is thus the third major battery project of the municipal energy supplier.

Energy Minister Christian Pegel, WEMAG project manager Jost Broichmann and WEMAG board member Thomas Murche (from left) jointly put the battery storage station WBS 500 into operation.

US triples energy storage installations, residential grows 10X to become largest sector

September 5, 2018: Wood Mackenzie projects that the U.S. energy storage market will reach well over $500 million in sales this year, following on 61.8 MW / 156.5 MWh of installations during the second quarter. Residential storage has grown at 61% per quarter since Q1 2017. The US Energy Storage Monitor shows 61.8 MW / 156.5 megawatt-hours (MWh) of energy storage deployed in the quarter, versus Q1 2018 which saw 43.6 MW / 126.3 MWh – growth of 42% and 24% quarter over quarter, respectively. California and Hawaii dominate the residential market, and are expected to continue to do so, with 72% of all installations. However, Massachusetts and Arizona have a chance at making a move pending their own market adjustments.

The residential market has shown the most consistent growth of the three sectors, with positive quarter-over-quarter numbers since the beginning of 2017 – cumulatively experiencing 60.6% quarterly growth. In fact, during this quarter residential was the leading sector in both MW and MWh installed. This aligns with prior research communicating 74% of residential customers have shown interest in energy storage.

The use of longer-duration batteries, able to discharge for several hours, has enabled balancing of solar with widespread storage.

US grid-connected battery energy capacity grew 68% last year

September 4, 2018: U.S. utilities increased their battery energy capacity 68 percent to 1.3 gigawatt-hours (GWh) by year-end 2017, according to a utility survey conducted by the Smart Electric Power Alliance (SEPA).  While the increase in battery power capacity, measured in watts, was just 31 percent, the installation of longer-duration batteries last year helped produce the bigger jump in battery energy capacity, measured in watt-hours. California utilities remained far in the lead in storage energy capacity, in response to state storage policies that support renewable goals. 

The SEPA report flags FERC Order 841 as a primary driver of near-term growth in storage. FERC Order 841 directs RTOs/ISOs (regional transmission organizations and independent system operators) to allow a storage resource to sell into the wholesale market all capacity, energy, and ancillary services that the resource is technically capable of providing.

Ireland has similar solar irradiation to that of the UK or Northern Germany, but has yet to seriously take advantage of its PV potential.

Over 1 GW of PV, 351 MW of storage approved in Ireland

September 3, 2018: The first round of Ireland’s newly introduced Enduring Connection Policy – 1 (ECP-1), introduced at the beginning of the year, has resulted in considerable success for solar PV and battery storage, with the technologies clearly outcompeting various forms of gas-fired generation, biomass, and wind energy. Irish grid operator authority, Eirgrid Group, said on Friday that it had approved applications totaling 252 MW of large-scale solar farms, 842 MW of small-scale solar systems, and 351 MW of storage capacity under its ECP-1 capacity application process. The policy, introduced at the start of 2018, was designed to create a new system for issuing connection offers for new generation and storage capacity.

Reportedly, applications under the DS3 component comprised 351 MW of battery storage capacity and 20 MW of hybrid plants. The DS3 requirement accepts applications that can provide Fast Frequency Response (FFR) and/or Primary Operating Reserve (POR), in line with grid code standards and transmission system operators’ list of proven technologies. The volume of approved projects under this requirement nearly exhausted the pre-set limit of 400 MW.

a virtual power plant is created that significantly improves network performance and stability and makes sustainable energy available at all times

North Sea island Borkum is a test field for innovative energy storage under real conditions

August 30, 2018: The North Sea island of Borkum is considered to be the ideal test laboratory for the energy transition: around 5,200 people live here, with an average of 2,000 hours of sunshine per year the sunshine is one of the highest in Germany, and Borkum is a completely enclosed island with simplified measuring conditions.
The test under real conditions has been running since 2015 within the framework of the project "NETfficient", which is supported by the European Commission. Thirteen partners from seven European countries want to develop a system on the island by the end of 2018 that will enable a 100% supply of renewable energies. For this purpose, photovoltaic systems with a total output of 279 kilowatts, prototypes of decentralized energy storage with a total capacity of 580 kilowatt hours as well as energy management software and smart meters have been installed. An energy storage unit with a capacity of 1,000 kilowatts and a capacity of 500 kilowatt hours was connected to the medium-voltage grid. By connecting generation plants and storage via the energy management system, a virtual power plant is created that significantly improves network performance and stability and makes sustainable energy available at all times.
The evaluation of the results should show how economically the virtual power plant can be operated and whether such a system can also be scaled and applied to other regions on a larger or smaller scale.

Germany reaches 100K home battery storage installations

Germany reaches 100K home battery storage installations

August 28,2018: A household just outside Berlin has become the recipient of the 100,000th grid-connected residential battery energy storage system in Germany. Parliamentary State Secretary at the Federal Ministry for Economic Affairs and Energy, Thomas Bareiß attended an official event to mark the system’s commissioning  in Eichwalde. The 100,000th solar storage system, which was a Solarwatt MyReserve residential device, joins 1 million homes in Germany now with their own PV system. Bareiß hailed the event as an “important milestone” that Germany has reached in its energy transition – referred to domestically as the Energiewende. The politician said that since 2013 battery costs have fallen by over 50%, making the Energiewende more affordable and expanding “flexibility options” open to grid operators for intelligent load management, while bolstering energy security.

The next milestone to aim for, BSW Solar‘s (German Solar Industry Association) managing director Carsten Körnig said, is to reach 200,000 systems in the next two years. The country appears to be on a more rapid trajectory to achieving that goal than many others. By way of illustration, there were around 50,000 systems installed by mid-2017. reported in July this year that as many as 37,000 units were sold and connected to the grid during last year, according to the European Market Monitor on Energy Storage (EMMES) from Delta-ee and trade association EASE.

55% growth over the next 5 years expected for grid energy storage systems

GTM Research expects stationary lithium-ion grid storage installs to grow 55% every year through 2022

August 22, 2018: According to a new report from GTM Research, global lithium-ion battery deployments over the next five years will grow by 55 percent annually. In other words, annual lithium-ion installations will grow more than eightfold, from 2 gigawatt-hours in 2017 to 18 in 2022.

This growth is starting from a tiny baseline — for comparison, electric-vehicle sales produced demand for 112 gigawatt-hours of batteries in 2017 alone. With 55 percent annual growth, though, the US analysts are convinced that grid storage will soon be substantial enough to alter the performance of electrical systems around the world.

And: Once electric cars have had a few more years on the road, their used batteries will become cheap, secondhand stationary storage devices.

CATL Lithium Ion Gigafab to be built in Thüringen, Germany

China is currently dominating the global production of lithium-ion cells.

From 2023, market researchers are also expecting Europe and the USA to be at the top.

August 13, 2018: At 134.8 GWh last year, China accounted for 60 percent of the global lithium-ion production capacity. This supremacy will keep on for a while.However, according to estimates by the London-based market research firm Benchmark Mineral Intelligence, the Chinese share will decline: initially to 58.6 percent in 2023 and then to 53.8 percent in 2028. The reason: The rapid market growth (to 564.5 GWh in 2023 and 998.5 GWh in 2028) also opens up opportunities for other companies and locations around the world. Benchmark boss Simon Moores speaks of 41 large factories worldwide, which are in the planning.

He predicts growing market shares above all for Europeans and North Americans. Europe's share of production capacity will rise from the current 5.3% to almost 20% by 2028, and the North American share from today's 5.7% to 14.8%. According to the British analysts, Germany will be ahead in Europe by 5.9 percent in 2028, followed by Poland and Sweden with 5 percent each. The plans for the construction of plants in Thuringia (CATL) and Sweden (Northvolt) have been included in the calculations as well as the battery cell factory of LG Chem in Poland which is currently being built.

1,000 MWh Energy Storage target in Massachusetts

US State Massachusetts’ New Clean Energy Bill establishes an energy storage target of 1,000 MWh by Dec. 31, 2025

On Aug. 9, Massachusetts Gov. Charlie Baker signed H.4857, An Act to Advance Clean Energy, into law. Among other things, the bill expands energy efficiency, increases the renewable portfolio standard (RPS), establishes a clean peak standard (CPS), sets an energy storage goal, and authorizes the solicitation of an additional 1,600 MW of offshore wind by 2035.

Among the most significant aspects of this bill is the provision that establishes a CPS, making Massachusetts the first state in the nation to require the delivery of “clean” resources during system “peak” demand periods. The legislation requires every retail electric supplier to provide a “minimum percentage of kilowatt-hour sales to end-use customers from clean peak resources.”

In addition to the storage opportunities created by the development of a CPS, the bill also calls for the creation of an energy storage target program and establishes an energy storage target of 1,000 MWh by Dec. 31, 2025.

U.S. Solar-Plus-Storage Market On the Rise

U.S. Solar-Plus-Storage Market On the Rise

July 2018: The U.S. solar-plus-storage market continues to expand, with 2018 set to see 261 MW of solar-paired storage deployed, 21% more than the total amount of storage (standalone and solar-paired) deployed in 2017. Record levels of behind-the-meter storage recently came on-line, much of it solar-paired, GTM Research says in a new Whitepaper. On the other side of the meter, utilities continue to procure large portfolios of solar-plus-storage, with increasingly competitive prices compared to incumbent generation resources. A recent example saw Xcel Energy procure 560 MW of solar paired with 275 MW/1,000 MWh of storage as part of its long-term resource planning.

Why do customers want solar-plus-storage? What market dynamics are drawing customers to add this technology to their homes or businesses? How are developers working the create value for both end customers, as well as to utilities? These questions are explored in the whitepaper. Free download on

Behind-the-meter energy storage powered Europe’s 49% yearly increase in installations

Behind-the-meter energy storage powered Europe’s 49% yearly increase in installations

5 Jul 2018: Europe’s installed base of electrical energy storage leaped by almost 50% during 2017 but perhaps the bigger takeaway is the growing share of battery systems installed behind-the-meter, an analyst has said. The overall European market, encompassing behind-the-meter residential and commercial and industrial (C&I), as well as front-of-meter grid-scale installations, compared with 2016 (around 400MWh), grew by 49% to close to 600MWh. That was the headline finding from ‘European Market Monitor on Energy Storage’ (EMMES), a six monthly-report produced by research firm Delta-EE, with the European Association for Storage of Energy (EASE).

Perhaps the most telling finding was that residential markets in Italy and Germany have grown more than anticipated. There is something more of a ‘natural growth factor’ associated with both main types of behind-the-meter (BTM) energy storage, residential and C&I, with the latter in particular expected to fuel a further 45% expansion of the market in 2018, says Valts Grintals, senior analyst in energy storage research at Delta-EE.

Number of the month: 118 billion

July 2018: The share of renewable energies in power generation in Germany in the first half of 2018 was for the first time ahead of the proportion of lignite and hard coal. According to initial estimates, renewable energies contributed almost 118 billion kWh to gross electricity generation. This corresponds to an increase of more than 10 percent compared to the same period of the previous year. Their share of electricity production in the first half of 2018 was around 36 percent. By contrast, power generation from lignite and hard coal has declined significantly, to around 114 billion kWh. This reports the German Federal Association of Energy and Water (BDEW).


The European Battery Alliance (EBA) was launched in October 2017 by Vice President Šefčovič.

European Battery Alliance (EBA) and Strategic Action Plan for Batteries

May 17, 2018: For Europe, battery production is a strategic imperative for clean energy transition and the competitiveness of its automotive sector. Moreover, the Commission's ‘New Industrial Policy Strategy’ goal is to make the EU the world leader in innovation, digitisation and decarbonisation. Therefore, the European Commission launched the 'European Battery Alliance' cooperation platform with key industrial stakeholders, interested Member States and the European Investment Bank In October 2017. More than 120 industrial and innovation actors are active under the Alliance.

The immediate objective is to create a competitive manufacturing value chain in Europe with sustainable battery cells at its core. According to some forecasts, Europe could capture a battery market of up to €250 billion a year from 2025 onwards. Covering the EU demand alone requires at least 10 to 20 ‘gigafactories’ (large-scale battery cell production facilities).

With the strategic action plan for batteries, the Commission adopted a comprehensive set of concrete measures to develop an innovative, sustainable and competitive battery 'ecosystem' in Europe. This approach will promote the production and use of high-performing batteries and set sustainability benchmarks throughout the value chain.

Webinar: When are commercial storage systems worthwhile?

April 26, 2018: In the context of the much-discussed energy transition, the use of large-scale storage systems is taking on an ever-greater role in commerce and industry, as well as for utilities. The aim is for storage systems to bridge the gap between the volatile infeed from renewable energy sources on the one hand and grid electricity demand on the other. As the grid is unable to store energy, exactly the same amount of power must be fed into it as consumers are drawing from it at any given moment. Linking up grids over large areas is of course another way to mitigate this issue. Economic assessments of storage system projects show that – with just a few exceptions – battery storage systems must perform multiple tasks to generate a good return on investment. As every task contributes to the storage system’s overall revenue, it is common to look at it in terms of multiple revenue paths that combine to give the total profit margin. Possible streams of revenue and cost savings include for example cutting peak loads, avoiding grid charges, atypical grid usage, marketing balancing power, optimizing self-consumption and providing reactive power.

The webinar with Hans Urban, a consultant in the field of renewable energies and e-mobility, will bring participants up to date on the latest expertise in this area.

The webinar has taken place on Thursday, May 17, 2018 at 4:00pm (in German only)

Renewables could make up two-thirds of the energy mix by 2050, with significantly improved energy intensity.

The “carbon budget” to keep global warming below 2 Degrees Celsius will run out in under 20 years, IRENA says in its 2018 report

April 2018: Keeping the global temperature rise below 2 degrees Celsius (°C) is technically feasible. It would also be more economically, socially and environmentally beneficial than the path resulting from current plans and policies, known in the IRENA (International Renewable Energy Agency) report as the Reference Case. However, the global energy system must undergo a profound transformation, replacing the present system that is largely based on fossil fuels.

The total share of renewable energy must rise from around 18% of total final energy consumption (in 2015) to around two-thirds by 2050. Over the same period, the share of renewables in the power sector would increase from around one-quarter to 85%, mostly through growth in solar and wind power generation. The energy intensity of the global economy will have to fall by about two-thirds, lowering energy demand in 2050 to slightly less than 2015 levels. This is achievable, despite significant population and economic growth, by substantially improving energy efficiency, the report finds. 

The analysis is based on IRENA’s global roadmap for scaling up renewables, known as REmap. IRENA’s report identifies six focus areas where policy and decision makers need to act. To learn more, download Global Energy Transformation: A Roadmap to 2050 .

sonnen und Engie Agree on Partnership

April 26, 2018: Since 2017, PV self-consumption systems in France have been supported with an investment bonus. At the same time, the electricity price has risen by about 20% in the past five years. In order to offer the two-thirds of the French population who are interested in a photovoltaic installation the opportunity to offer self-generated electricity in the evening and at night, the storage provider sonnen and Engie have joined forces to offer the customer of the energy supplier a complete package for self-consumption. Under the name My Power they receive a PV system and a sonnenBatterie.
The French storage market is still in its early stages, but exactly for that very reason it has great potential. The cooperation gives sonnen access to 4.4 million homeowners and new customers.
sonnen already had its sonnenBatterie on the French market, certified it and trained numerous fitters on site. In addition to its  most important market Germany, sonnen also operates in other European countries, as well as in the USA and Australia.
