KG was founded in the 2015 calendar year, also as a standard limited partnership (Einheits-KG) domiciled in Aachen, with the same business purpose as Trianel Onshore Windkraftwerke GmbH & Co. KG.Trianel Finanzdienste GmbH, domiciled in Aachen, is a wholly owned subsidiary of Trianel GmbH. The activities of the Trianel Group which require authorisation for the provision of financial services pursuant to Section 32, para. 1 of the German Banking Act (Kreditwesengesetz, KWG) are pooled in this company.The Dutch sales and distribution company Trianel Energie B.V. domiciled in Maastricht was forced to apply forinsolvency at the end of 2012 due to customer default. The insolvency proceedings are still ongoing.GESY Green Energy Systems GmbH is domiciled in Berlin, and was working together in direct marketing ofrenewable energy sources with Trianel in the 2017 reporting year. As part of the restructuring of direct marketing, the cooperation with Green Energy Systems GmbH was terminated by Trianel on 31 December 2017.The sale of the participating interests is currently subject to approval by the shareholders of Trianel.The strategic orientation of Trianel Service GmbH domiciled in Aachen is currently under review, as a resultof which business operations have been suspended.1.2 Business fieldsTrianel GmbH’s business activities aim to enhance the competitiveness and therefore independence of municipal utilities. As the largest European cooperation of municipal utilities, Trianel GmbH utilises the potential ofliberalised energy markets by pooling shared interests from the municipal environment. For example, thisopens up business fields which would not be economically viable for individual municipal utilities.Trianel GmbH operates in multiple sectors of the energy industry throughout the entire value chain. Its corebusiness is trading, procurement and supply of energy. The company purchases energy on wholesale marketsfor redistributors and municipal utilities on wholesale markets, providing easy market access for its customers.In this way, Trianel helps municipal utilities supply their end customers. In addition, Trianel optimises energyindustry management of conventional and renewable energy generation systems for municipal utilities andindustrial customers. For existing renewable energy projects and major electricity generation and gas storagesystems, Trianel takes on the energy business and commercial management and optimisation of thesystems.In addition, Trianel is active in project development (offshore wind, onshore wind, photovoltaic systems). Together with municipal utilities, it develops new projects or analyses and extends existing systems.As a third element, Trianel designs and supports the business activities of municipal utilities in end-customerfocused areas, such as smart metering, energy efficiency and expansion of electromobility.The further expansion of renewable energies, the increasing decentralisation and decarbonisation of the energy industry and the innovation potential due to digitalisation and automation are currently dominating allbusiness fields of Trianel.All activities of Trianel GmbH are developed in close coordination with the business aims of the shareholdercompanies and tailored for their needs and circumstances.10

Management ReportCompany situation1.3 Important products and services, business processes and projectsTrianel GmbH operates in all trading markets for electricity and gas products, both as a trading partner forbilateral transactions (OTC market) and as a member of the most important energy exchanges. Market accessfor electricity includes the German, Dutch, Belgian, Swiss and French market areas. In the gas sector, Trianelcovers the German market areas, for H-gas and L-gas, as well as the liquid TTF market. Diverse sales productsin the delivery sector are based on activities on the market. That allows Trianel customers to purchase tradeproducts directly.Energy business products and services:In 2017, the portfolio management on the procurement and generation side again formed a main pillar ofthe activities in the energy business sector. It consists of electricity and gas procurement, marketing and securing electricity from own generation plants and management of storage facilities for our customers.Trianel is developing a central interface for pooling trade and sales information for municipal utilities and industrial customers, the integrated, web-based monitoring and control platform Trianel DESK. In 2017, optimising the internal processes for developing the platform was the priority for the development of TrianelDESK, in addition to optimising the internal processes. To this end, the energy trading IT division was established, which creates the technical and organisational preconditions to develop digital processing of portfoliomanagement and energy trading. Digitalisation via Trianel DESK gives portfolio management and energy trading efficiency boosts and process excellence, creating more scope for a more individual customer care andmarket consulting. From forecasts to pricing, portfolio structuring, trading standard and non-standard products to balancing group accounting, customers are to be provided with all energy business procurement andsales functions for electricity and gas in a consistent, interactive, web-based customer interface on the TrianelDESK. Trianel DESK aims to optimise processes in interaction with customers and within the Trianelorganisation.Besides developing the applications of the Trianel DESK, customer and process integration of the former location of Leipzig into the system infrastructure in Aachen was the priority in procurement management. Inthis context, comprehensive handovers, process optimisations and strategy meetings were held in cooperationwith our customers.With a view to the targeted extension to the industrial customer segment, we must emphasise that a majorindustrial customer was attracted in 2017, beginning on 1 January 2018.In the ranking of the generation portfolio managers of shareholders in the Trianel coal-fired power station inLünen, Trianel Finanzdienste GmbH (TFD) once again topped the charts when comparing all companies involved in power station optimisation, generating a seven-figure revenue surplus for its customers. In additionto this, TFD expanded its role as a comprehensive service provider for optimised marketing of generationplants of all types.Via marketing activities in the spot, intraday and balancing energy markets, an additional 3.2 million wasearned in the management of Lünen coal-fired power station (TKL). In addition to this, 2.7 million was savedas part of shortfall management compared with the failure reserve contract. The shareholders in TKL benefitfrom both. Trianel also benefits as part of the contractually defined variable remuneration of these resultsachieved.11

Trianel GmbHAnnual Report 2017For Gaskraftwerk Hamm, the “warm reserve” agreed with the TGH shareholders generated a net income of 5.6 million. This value is approx. 0.9 million above the originally planned value. In addition, a block of thepower station was marketed to a market partner as part of an option transaction for 2018. Compared withleasing in 2017, the price for this has almost doubled. Trianel holds a one-third share in these earnings forthe above-mentioned period.In direct marketing, Trianel repositioned itself in 2017 and reviewed its portfolio of roughly 5,200 MW (as of1 January 2017). Trianel’s has many years of experience in direct marketing and continues to focus on thisbusiness field as long as it is economically attractive. Given the increasing margin pressure in direct marketing, Trianel consolidated and restructured its portfolio during 2017. To this end, the portfolio was reducedsignificantly to 3,200 MW as of 1 January 2018. Most of the direct marketing portfolio consist of windenergy.End-customer focused services and products:Trianel supports municipal utility in developing from mere suppliers to modern energy service providers andoffers a range of services to create synergies here too. In particular, this will focus on the challenges that municipal utilities must overcome due to the changing requirements of end customers. Trianel enables municipalutilities to look into the latest trends like digitalisation, sustainable mobility, energy efficiency and energy autonomy, and implement specific projects together. The goal is to support municipal utilities in a wide rangeof transformation processes.To meet the needs of municipal utilities in digitalisation, Trianel founded the first exclusively municipal DigitalLab in 2017 with 38 municipal utilities. The aim of the idea and innovation workshop for municipal utilitiesis to implement digital projects in municipal utilities in short periods and learn from experiences together. TheTrianel Digital Lab aims to analyse the opportunities of digitalisation and apply them specifically. This allowssynergies to be developed in applying digital solutions, and possibly also new business models to be developed jointly.In addition to founding the Trianel Digital Lab, another focus for the Municipal Utility Sales Solutions businessunit (now Digital Energy Solutions) was selling the sales platform for PV Contracting Models Trianel PED. Asearly as the end of 2016, initial talks were held on the sale of the Trianel PED platform, to focus activities inthe Municipal Utility Sales Solutions business unit to a greater extent. As business on the Trianel PED platformcontinued to develop well, a potential buyer was found in Vattenfall Smarter Living GmbH in early 2017. Theplatform was handed over to Vattenfall on 30 June 2017. At the same time, the ten employees required tooperate the platform also transferred to Vattenfall. The customers on the platform continue to run the business, with a few exceptions. Trianel supports Vattenfall with sales and support for the municipal utilities aspart of a service agreement.2017 was dominated by a reorientation in the energy efficiency sector, as the current legal general conditionsdeny municipal utilities the opportunity to remedy inefficiencies identified in audits of industrial customers.For reasons of neutrality, these measures must be implemented by third parties. For this reason, Trianel hasconcentrated significantly on consulting. A change in the regulatory framework conditions is expected for thenear future, which could facilitate more comprehensive activities in this area.Introduction of Smart Metering is a key precondition for digitalising energy industry processes. Since 2012,Trianel has been building the required expertise for the pending rollout and the technical preconditions forgateway administration.12

Management ReportCompany situationIn 2017, the first 14 municipal utilities chose Trianel as a service provider in gateway administration. This isless than originally expected, as the companies involved are slow to establish the technical general conditionsfor the start of the smart meter rollout and award decisions are being delayed. Other contract conclusionswith municipal utility customers and the start of the rollout are now expected in the first half of 2018.Trianel Academy has further consolidated its position in the market for training and consulting. With the newe-learning product, a second mainstay was developed, which has now already been implemented for the firstcustomers, and offers major potential for scaling.Project development and projects:The project development business of Trianel GmbH now focuses almost entirely on renewable energy projects.For example, the second expansion stage of the Borkum offshore wind farm (TWB II) was launched successfully in 2015. Together with 17 municipal utilities from the Trianel Group, as well as EWE Oldenburg andewz from Switzerland, Trianel GmbH will develop the next 200 MW. Trianel GmbH’soffshore segment is responsible for construction processing with EWE OSS. TrianelGmbH is also preparing the commercial and superordinate operational managementfor TWB II from 2020 on. 2017 was dominated by the tenders and award of the maw i l l b e d e v e l o p e d b y Tr i a n e l G m b Hjor subsections and conclusion of the equity and borrowed capital process. The decitogether with 17 municipal utilitiession to build for the offshore wind farm was passed by the shareholders on 7 Aprilf r o m t h e Tr i a n e l G r o u p , a s w e l l a s2017. The financial close was approved on 28 April 2017.EWE Oldenburg and ewz. 200 MWThe first asset company, Trianel Onshore Windkraftwerke GmbH & Co. KG (TOW), concluded its investmentactivities as planned, and now operates eight wind farms, with a total capacity of roughly 100 MW after thelatest turbines were commissioned. As a result, TOW is now focusing on operating the wind farms.When success of TOW was foreseeable, 38 municipal shareholders founded the successor company TrianelErneuerbare Energien GmbH & Co. KG (TEE) in 2015. TEE focuses on both wind farms and solar parks. In 2017,it succeeded in expanding to 260 MW. Another 300 MW are being processed in roughly 20 projects.Retaining the existing options was the priority in the conventional large-scale project sectors at the Krefeldand Karlsruhe locations.1.4 Management and controlIn addition to Sven Becker as Management Spokesman, Dr Oliver Runte has been appointed as ManagingDirector of Trianel GmbH since early 2017. The Trianel Shareholders’ Committee and the twelve-strong Supervisory Board are among the other corporate bodies.13
