Energy storage Storage facilities are essential for energy supplies based on renewable resources. E.ON is working on a variety of different technologies and innovations for storing electric power and delivering power, gas or heat at a later point in time. 17 4 Dear Reader, The Managing Directors of E.ON Gas Storage with members of the team New impetus and greater flexibility for the highly competitive gas storage market throughout Europe – these are the objectives of E.ON Gas Storage GmbH (EGS). Not only is demand for natural gas rising; production from indigenous sources is falling and growing quantities of gas are being imported from more and more distant regions such as Russia and Norway. Storage facilities are therefore crucially important for the European natural gas market. As an essential buffer between supplies from producer countries at almost constant flow rates throughout the year and demand, which is subject to severe seasonal fluctuation, storage facilities play a key role in ensuring secure natural gas supplies. They also offer market players the versatility they need to face growing competition. Companies making effective use of storage capacities can react faster and more flexibly to quantity and price fluctuations. We not only support safe, competitive natural gas supplies in line with demand. Natural gas storage facilities are also playing a key role in the implementation of the energy transition. As one of the largest European gas storage companies, we are committed to progress and our activities in the field of technology and innovation. It is our objective to develop innovative technologies for the transportation and storage of energy and to show once more that sustainability is the key to the future. To learn more about this area as well as E.ON Gas Storage, its core competences and services, just read this brochure. We offer our capacities to the market on a transparent, fair and non-discriminatory basis. In this context, E.ON Gas Storage has taken on the role of a pioneer, strengthening future-oriented market structures and joining the competition initiative of the E.ON Group. Our product portfolio sets standards in the marketplace.

E.ON Gas Storage shapes storage business and strengthens competitive market structures throughout Europe with innovative products and services. The company is committed to storage solutions that are fair, flexible and transparent in the interests of all market players. 7 8 Storage solution partner throughout Europe Within the E.ON Group, E.ON Gas Storage pools the expertise developed over the decades for gas storage throughout Europe. In August 2008, E.ON Gas Storage GmbH started its activities. Together with its Austrian affiliate Gas Storage Austria, the company has storage capacities in a total of 16 underground storage facilities at 14 locations in Germany and Austria. The total working gas capacity of these facilities is currently about 8.5 billion cubic metres. Including the company‘s subsidiaries in Hungary and the UK, the total working gas capacity available in Europe is more than 12 billion cubic metres. This means that E.ON Gas Storage is already one of the major European gas storage companies. European activities. In Hungary, wholly owned subsidiary E.ON Földgaz Storage operates four underground storage facilities with a working gas capacity currently totalling about 4.2 billion cubic metres. Via another wholly owned subsidiary, E.ON Gas Storage UK, the company is also expanding its storage capacities to provide support for trading business and to meet peak demand. Following the commissioning of Holford gas storage facility in Cheshire, EGS UK already has a working gas capacity of 0.2 billion cubic metres. Since the commissioning of the 7Fields natural gas storage facility by Austrian affiliate Gas Storage Austria in 2011, the company is also represented on the Austrian market. With this project, E.ON Gas Storage is breaking new ground together with its partner Rohöl-Aufsuchungs AG (RAG) and has linked several depleted natural gas fields to form a single storage facility. E.ON Gas Storage is also expanding the capacity available at its existing sites, such as Epe and the “ESE-Erdgasspeicher Etzel” storage facility commissioned in 2012. These storage projects will continue to boost the company’s working gas volume in Germany and Austria in the future. 9 Tailor-made storage capacities. E.ON Gas Storage experts are available to assist all customers in the planning and implementation of tailor-made gas storage solutions. The company‘s storage capacities and services are available to all customers on a fair, transparent, non-discriminatory basis in line with the requirements of the amended German Energy Industry Act and the third internal market package. The company also operates in line with the European Guidelines for Good Practice for Storage System Operators (GGPSSO). The guidelines are voluntary agreements going far beyond the current requirements of German and European energy law. Innovation across the board. Outside its core business activities as an owner, operator and service provider in the gas storage sector, E.ON Gas Storage is also active in another future-oriented field. EGS heads the “E.ON Innovation Center Energy Storage”, which is responsible for coordinating all activities of the E.ON Group in the field of energy storage. E.ON is pursuing a variety of approaches ranging from optimizing and improving the efficiency of proven technologies to highly innovative solutions. Depending on technical requirements, work is carried out on various solutions in the field of electric power storage (e.g. stationary battery storage), power to gas (e.g. transformation of power from renewable sources into hydrogen or methane, possibly combined with underground storage) or heat storage for cogeneration. The objective of the E.ON Innovation Center is to assess these technologies, test them and finally to establish them within the energy system. The center is laying a firm foundation for a key contribution to the growing market for renewable energies. E.ON Gas Storage – facts and figures at a glance Sales: more than 700 million euros (2011) Storage facilities: 16 underground storage facilities at 14 locations in Germany and Austria, four in Hungary and one in the UK Working gas volume: 8.5 billion cubic metres in Germany/more than 12 billion cubic metres throughout Europe December 2012 10 Ample space for natural gas Storage facilities are crucially important for the natural gas market. They ensure security of supply and provide market players with the flexibility they need in a competitive market, as well as playing a key role in the implementation of the energy transition. E.ON Gas Storage offers gas storage capacities in cavern and porous rock facilities throughout Europe. In Germany, 48 natural gas storage facilities with a total capacity of about 20.4 billion cubic metres are currently in operation. The German gas industry therefore has the largest natural gas storage volume in the European Union. According to the International Gas Union (IGU), Germany has the fourth-largest storage capacity of any country, after the USA, Russia and Ukraine. In the context of growing competition, the optimum utilization and expansion of existing capacities are essential. E.ON Gas Storage plays a key role in this area. Deployment of storage capacities in line with requirements: German storage capacities are currently divided between 22 porous rock and 26 cavern facilities. The two types of storage facility not only have different geological characteristics (see box) but also different advantages. In contrast to cavern storage facilities, porous rock facilities normally have a larger storage capacity. On the other hand, cavern storage facilities feature higher injection and withdrawal rates. The reason is quite simple: caverns are artificially created cavities linked to the surface by deep wells allowing gas to be injected and withdrawn from the facility directly without any obstacles. In the case of porous rock storage, the gas must first flow through the porous rock to the well. To a large extent, the injection and withdrawal rates possible at a porous rock storage facility are therefore determined by the flow properties of the rock formation. Porous rock storage facilities are ideally suited for adapting to seasonal demand fluctuations. They are filled in the summer and emptied during the heating season in the winter. In other words, the working gas is normally injected and withdrawn once per year. In contrast, cavern storage facilities are used to meet extreme demand peaks. They may be filled and emptied several times per year and are therefore especially interesting in connection with spot trading. 11 Underground storage of natural gas Porous rock facility Cavern facility Station Aquifer/gas field Riser Water Observation well Caverns Gas-tight caprock Salt formation Porous rock and cavern storage facilities There are two types of underground storage facilities for natural gas: porous rock and cavern facilities. Porous rock storage facilities are mainly developed in depleted gas or oil fields. Gas injected into storage is stored basically in the same way as in nature, in the pores of rock formations permeable to gas, sealed off by a gas-tight layer or “caprock”. In contrast to porous rock facilities, the space required for storage in a cavern facility is created artificially. Salt domes and thick salt formations may be suitable sites for a cavern storage facility. Via a deep well, which is later used for gas injection and withdrawal, salt is leached out of the formation in a controlled way using water. The cavity created in this way can then be used for the storage of natural gas. For reservoir engineering reasons, a certain volume of natural gas (the “cushion gas”) must always remain in a natural gas storage facility. The gas which is actually available for withdrawal is referred to as “working gas”. Expanding safely! E.ON Gas Storage GmbH (EGS) has been responsible for the operation of storage facilities and has also been the central energy storage unit of the E.ON Group since August 2008. Formerly, the operations personnel of the storage facilities were provided by Open Grid Europe GmbH under a service contract. Since 1 December 2012, the situation has changed and, with it, the role and responsibilities of EGS. “We have already operated the ESE-Erdgasspeicher Etzel, which is currently in the process of commissioning, with our own personnel since April 2012,” says Andreas Böhmer, Head of Operations, Technical Service and HSEQ. “Now we have also assumed responsibility for operations at Epe, Breitbrunn and Bierwang.” He and his team members Holger Schmidt and Carsten Starrach are responsible for the health, safety, crisis, environmental and quality management system (HSEQ-System). In connection with the extended responsibilities of EGS, it was necessary to expand and also update the Management Systems in the fifth year of the company’s existence. The new EGS system received confirmation on 30 October 2012 when the company was again certified by independent experts and auditors under the standards DIN EN ISO 9001:2008 (quality management), HSEQ management means teamwork (from left to right: Andreas Böhmer, Holger Schmidt and Carsten Starrach) DIN EN ISO 14001:2005 (environmental management), OHSAS 18001:2008 (health and safety management) and DVGW G 1000 (technical safety management (TSM)). 12 How is gas stored? Natural gas injection and withdrawal process 1 Gas transmission system 2 Filters 3 Metering station 4 Compressor station 5 Cooler 6 Well head (on each well) 7 Well 8 Salt formation 9 Caverns 10 Gas-tight caprock/ cavern wall 11 Gas-bearing section 12 Water-bearing section 13 Control room 14 Preheating system 15 Pressure let-down system 16 Dehydration unit Via the inlet flange of the storage station, the gas carried by the gas transmission system (1) reaches a filter unit (2) where possible impurities are removed from the flowing gas. Downstream from the filter unit, the gas flow and quality are measured (3). As the transmission system pressure is lower than the storage pressure, the gas pressure is boosted to the value required for injection by a compressor station (4). The compression process generates heat and the gas is therefore cooled (5) before being fed to the well head (6), where it is injected into caverns (9) or natural storage formations (porous rock storage facilities) (11) via wells (7). Caverns are created in suitable salt formations by solution mining (8). Natural storage formations are only suitable for the storage of natural gas if they are covered by a gas-tight caprock layer. This is the case, for example, in depleted gas fields. Finally, the gas is routed through the gas metering station (3) before being returned to the transmission system (1), which supplies gas to customers. How safe are storage facilities? Porous rock storage facilities in depleted oil or gas fields have Under the gas-bearing section of a porous rock storage facility (11), there is a water-bearing section (12) which forms a boundary to the storage facility. Salt caverns can be used for gas storage because the salt formation is gas-tight. Any water produced from the facility during gas withdrawal must be removed from the flowing gas. Preheating (14) is necessary to compensate for the cooling of the gas during pressure reduction (15). Then any residual moisture is removed from the gas stream by dehydration (16). put their integrity to the test over millions of years. Because of the tightness ensured by the surrounding salt, cavern storage facilities are ideal containers for the storage of gas. In addition, the extremely low above-ground space requirements conserve resources and protect the environment. The underground storage of natural gas is therefore not only the most environmentally compatible but also the safest method of storage. In the future, underground storage will continue to make a sustained contribution to flexible, secure natural gas supplies in Germany. 13 Marketing of storage products We offer individual storage products with flexible price models. Our portfolio ranges from storage products to compensate for short-term demand peaks to storage capacity which can be used on a seasonal basis. 14 Individual and flexible products Product portfolio. We offer our customers a wide product range in the field of natural gas storage based on expertise and know-how. Our comprehensive, innovative product portfolio with a variety of price models is ideally tailored to market requirements. In addition to our established fixed-price products, we also offer innovative variants based on market prices. Storage bundles and additional capacities. Our products are based on bundled storage capacities, or so-called storage bundles. A storage bundle is a combination of working gas capacity with injection rate and withdrawal rate, with all three components in a fixed ratio. Firm capacities have the advantage that they are available to the customer continuously under the conditions agreed in the contract. These capacities can always be provided by the storage facility. In addition to each storage bundle, customers may reserve non-bundled storage capacity as additional capacity. This allows our customers to use storage capacities flexibly. Customers can adapt the capacities available by combining storage bundles and additional capacity in line with their specific wishes. Storage capacities can also be further optimized. We offer capacities both on a firm and on an interruptible basis with an appropriate price reduction. Bundled However, storage facilities can do much more. We achieve the best possible utilization of our storage facilities by offering interruptible capacities. Interruptible capacities are available subject to certain restrictions. The capacity is technically available but is not always fully available in practice, depending on temperature and pressure conditions. Although the probability that capacities will be interrupted is currently extremely low, interruptible capacities are therefore less expensive. Non-bundled Injection rate Working gas Injection rate Withdrawal rate and/or Working gas capacity and/or Withdrawal rate Flexible storage utilization 15 Fixed-price products. We offer both firm and interruptible storage bundles and additional capacities at fixed prices. Our customers can book fixed-price products for terms of up to 15 years. These products therefore offer customers a decisive advantage. They know the precise price in advance and can therefore plan their long-term demand. Depending on the contract term, we offer attractive pricing models including discounts of up to 15 % to our customers. Indexed products. In addition to our established fixed-price products we have developed indexed products based on market prices in close cooperation with our customers. In contrast to our fixed-price products, the pricing of these indexed products is variable. The specific price per unit of storage capacity is not fixed at the time when the capacity is booked. The price of the product is determined directly by the market and is referred to the summer/winter spread using a price formula. The summer/winter spread is the difference between gas prices quoted on trading markets for the summer and winter seasons. In the current market environment, this spread is a key factor in boosting demand for storage services and is therefore well-suited for ensuring that the prices of indexed products reflect market price levels. Indexed products are offered depending on market developments and normally have an average term between three and five years. Of course, our customers can also diversify their portfolio by combining fixed-price and indexed products. Price system for indexed products Both maximum and minimum prices may be assigned to indexed products; these apply irrespective of the development of the summer/winter spread. This ensures a balanced distribution of market risks between the customer and the storage service provider. The price payable is determined at annual intervals before the beginning of each storage year. Price determination is based on market developments and the agreed price formula. Supplementary products. We offer a number of supplementary products to our customers in addition to fixed-price and indexed products. These include the storage of bio-natural gas and short-term trading in injection and withdrawal rates via our day-ahead platform, flat products and a transfer right that allows customers to transfer products between storage facilities. You will find more detailed information on the supplementary products on our homepage at www.eon-gas-storage.com. Product development. Our objective is to comprehensively serve the needs of our customers. Our products and services are therefore developed in a process of direct dialogue with our customers. We are continually developing other interesting, competitive products. We welcome product ideas and wishes from our customers and do our utmost to implement them as rapidly as possible. Of course, we make the products developed available to all market players on a non-discriminatory basis. 16 Storage locations and market access We offer various storage bundles at our storage locations in Germany. There are five storage bundle types (A, B, C, D and E). Depending on the individual bundles, our customers have a choice of storage products ranging from fast churn storage (type A) to seasonal storage (type E). The map shows the types of bundle available at each storage facility. Details of the bundles are given in the table below, in which the same colour coding is used. Storage bundles offered and regional distribution Storage bundle Withdrawal rate per bundle (MWh/h) A B C D E 10.00 10.00 10.00 10.00 10.00 Working gas per bundle (GWh) 5.00 7.50 10.00 15.00 20.00 Injection rate per bundle (MWh/h) 2.50 3.00 3.33 4.55 5.56 Ratio of working gas to withdrawal rate per bundle (days)* 29 44 59 89 118 Ratio of working gas to injection rate per bundle (days)* 95 119 143 157 171 2.94 2.24 1.81 1.48 1.26 Churn rate (p.a.)* * based on standard characteristic curve Market access. As a result of the wide variety of storage locations, our natural gas storage facilities provide access to all relevant trading points in Germany (NCG and Gaspool), the Netherlands (TTF) and Austria (CEGH). As a general principle, we offer our storage capacities directly at the appropriate storage connection point. This means that transport is not automatically included in the services. As a result, each customer has the opportunity to make bookings for transport in line with its own requirements. If the customer so wishes, we are prepared to provide support for the steps required for transport bookings. The advantage for our customers is that they can select the product best-suited for their needs from the storage capacities and transport rights available. 17 Energy storage E.ON Gas Storage already plays a major role in innovative storage solutions. The expansion of fluctuating power generation from renewable sources such as wind and solar power and variations in consumption will make it essential to store energy in the future. 18 The energy industry has developed over many decades in line with demand. In the complex market structures that have evolved over this period, the cornerstones of supply security are lignite, hard coal, uranium, oil and gas. Without adequate supplies of energy, the levels of prosperity experienced nowadays in the form of heating, light, mechanical work, communications and mobility would not be possible. However, this tried and tested system is subject to considerable influences which call for significant changes. The status quo. The raw materials needed for energy supplies are taken from deposits which are not evenly distributed around the world and are, in many cases, located in regions affected by political instability. Globalization is leading to higher economic growth in successful emerging countries but also to more competition for fossil fuels. These developments are combined with growing concerns with respect to global climate change, leading to higher temperatures and dramatic environmental and economic consequences. The emission of carbon dioxide from combustion processes is considered to be the main cause. For this reason, energy companies have invested billions of euros in the expansion of power supply from renewable sources such as wind, water, solar, biomass and geothermal energy over the past few years. Power plants are normally built at sites which are conveniently located with reference to centers of demand, with a view to keeping distances as short as possible. However, the dramatic expansion of power from renewable sources poses a major new challenge. Like fossil fuels, renewable energy sources are mainly available in certain areas. However, unlike fossil fuels, these energy sources are initially not linked to specific materials and cannot be simply transported and stored until they are required. On the contrary, energy from renewable sources is available when and where the wind blows or the sun shines, often at remote locations or times of low demand. Energy demand has always been subject to fluctuation, but this means that energy generation will also fluctuate and take place at considerable distances. As a result, we already face temporary network overloading resulting in the forced shut-down of generating facilities and preventing optimum use of the system. At a later stage, shortages may also occur. Attempts are being made to avoid these problems by expanding power grids but this assumes that power will always be generated somewhere and required somewhere at the same time. This assumption does not necessarily apply and the solution adopted can be ideally supplemented by the storage of energy. Energy storage solutions. There are various possibilities of storing energy. Depending on technical requirements, small, distributed, short-term storage facilities or larger, more centralized solutions for seasonal storage are available. These include: • electrical storage (e.g. batteries) • storage in the form of gas (e.g. conversion of power into hydrogen, the so-called “Power to Gas” technology or compressed air storage) • heat storage (e.g. for cogeneration plants) 19 Dr. Klaus Peter Röttgen, Head of Technology and Innovation at E.ON Gas Storage and the E.ON Innovation Center Energy Storage Energy storage – the key to the energy transition Interview with Dr. Klaus Peter Röttgen, Head of Technology and Innovation at E.ON Gas Storage and the E.ON Innovation Center Energy Storage What precisely is the ”E.ON Innovation Center Energy Storage“? E.ON has a number of innovation centers throughout the Group. Each of them is concerned with a specific technology and coordinates the development of this technology for the entire Group. E.ON Gas Storage heads the E.ON Innovation Center Energy Storage. Depending on technical requirements, the Center works on a number of different technologies for the storage of electric power and the later use of electricity, gas or heat. Why are energy storage facilities so important now and why will they be so important in the future? Storage is essential for energy supplies on the basis of renewable resources. Storage facilities cannot replace network expansion but they add to the system the possibility of using energy, which has been generated, at a later date. This may be necessary, for example, in order to improve on-site utilization of power from photovoltaic systems or to make the supply of power to the grid compatible with network conditions. Storage is also important in the event of unfavourable wind situations in large geographic areas or a lack of sunlight, as well as for seasonal balancing purposes. Are energy storage facilities already available and what storage systems are currently being developed? In addition to the major natural gas storage facilities which have been successfully operated by E.ON Gas Storage for decades, it is also possible to expand existing pumped storage facilities. Apart from these possibilities, the main areas of special interest are as follows: Firstly, battery storage. With batteries, container-sized domestic or regional units can be installed in a distributed configuration. A network of a large number of batteries offers considerable storage potential. This would also apply if the batteries of electric vehicles could be used for the energy system. 20 A second significant area is Power to Gas. When excess electric power is available, it is used for producing hydrogen by electrolysis. This hydrogen can then be made available for the heat energy market, industry or power generation. The fact that the existing natural gas infrastructure can be used means that considerable storage potential is available. Methanization, the combination of hydrogen with carbon dioxide and conversion into methane, even produces gas of natural gas quality from renewable sources which can be fed to existing natural gas systems without any chemical limits. Power to Gas can also boost progress with environmentally compatible hydrogen technology. The third area is heat storage, for example in the cogeneration sector in connection with solar thermal power stations or energy storage in the form of compressed air. E.ON also has many years of experience in this field. What projects are being implemented? We intend to make an active contribution to the integration of renewable energy sources by developing new, advanced, environmentally compatible technologies. However, new types of energy storage can only be developed on the basis of creative ideas for new systems and the willingness to try these systems out in practice. E.ON is therefore implementing various pilot projects. For example, the Power to Gas pilot plant at Falkenhagen in Brandenburg is being constructed by E.ON Gas Storage and operated in cooperation with E.ON edis. In future, this plant will allow the storage of wind power in the natural gas network. This is the first pilot plant of its type in the world, with an electrical capacity of 2 MW, covering the entire process from the receipt of wind power through to the injection of hydrogen into the natural gas network. Through this project, we intend to demonstrate that the process functions properly, to collect operational experience and to work intensively on improving the efficiency of plants of this type. Another example is the “SmartRegion Pellworm” project which is being implemented in cooperation with E.ON Hanse. The North Sea island of Pellworm is to become a model region for smart power networks and the local storage of electricity generated from renewable sources. The objective is to link power consumers with renewable generating facilities in such a way that the generation and use of electric power are harmonized more effectively. When large quantities of power are generated on the island as a result of good wind conditions and sunlight, the power will, in future, be stored directly in high-performance stationary batteries and in domestic heating systems. Where possible, excess electric power will not be wasted. In the event of electric power deficits, imports are also to be avoided to the greatest extent possible. For us, technology and innovation are top priorities, especially in view of the challenges posed by the energy transition, not only in Germany. Do you expect large-scale energy storage projects to be realized? With our ideas and projects, we are committed to making a significant contribution to the integration of renewable energy sources. The primary objective is to ensure an efficient balance between the expansion of renewable energies and electric power systems on the one hand and the flexibility provided by storage facilities and consumption control on the other hand. However, the way in which the configuration of international energy markets develops will define the energy storage facilities to be provided. In general, an energy transition will not be possible without energy storage facilities. Furthermore, the energy transition will be considerably more costeffective with storage, as storage will make the system more efficient and will reduce the volume of conventional reserves which will need to be kept available. 21 ”Power to Gas“ pilot plant Falkenhagen The wind blows when it wants to – sometimes more and sometimes less than you need. That’s why we are transferring wind power to the network. How can you store wind and solar power in an environmentally compatible way for later use? One highly promising solution is “chemical storage”, which involves the conversion of excess wind power into hydrogen – Power to Gas. Our new pilot plant at Falkenhagen in Brandenburg makes sure that the electricity generated when there is too much wind and the network is overloaded is no longer wasted. The electricity is used for an electrolysis process, producing hydrogen and oxygen. We then feed the hydrogen at a certain blending ratio into the existing natural gas system, a very large transport and storage system that is already available. With an electrical capacity of 2 MW and a hydrogen production rate of 360 m³/hour, we will be demonstrating the entire chemical storage process chain at Falkenhagen from 2013. The gas produced using renewable energy sources can be used effectively at any time and any place – for heating, mobility or power generation. Although electrolysis is already a proven technology, the plant will allow us to collect essential operating experience and optimize the operating concept for the market. This process means that electricity generated from renewable sources no longer needs to be used when and where it is generated. Power from renewable sources can then be made available at any time.
