Orders were up clearly year-over-year, due mainly to higher orders in the new-unit business. Volume from large orders increased significantly year-over-year; among the contract wins was a € 0.4 billion order for a combined-cycle power plant, including service in France; a HVDC order worth € 0.4 billion in Germany; a € 0.3 billion order for a large offshore grid connection project in the U. K.; and a € 0.3 billion order in the solutions business in Brazil. Order intake increased in all three reporting regions, with the Americas posting double-digit growth. Gas and Power ’s revenue decreased moderately year-over-year in a continuing difficult market environment as the new-unit businesses recorded lower revenue compared to fiscal 2018 following weak order entry in prior years. On a geographic basis, revenue decreased in the regions Europe, C. I. S., Africa, Middle East and Asia, Australia, partly offset by growth in the Americas. Despite a continuing strong contribution from the service business and positive effects from project execution and completion, Adjusted EBITA was down year-over-year on lower revenue, price declines and reduced capacity utilization. In addition, Adjusted EBITA in fiscal 2018 benefited from gains totaling € 166 million from two divestments. Severance charges were € 242 million in fiscal 2019 compared to € 374 million in fiscal 2018. Gas and Power ’s order backlog was € 51 billion at the end of the fiscal year, of which € 13 billion are expected to be converted into revenue in fiscal 2020. These results reflected a highly competitive market environment. We expect the power generation market overall to remain challenging with market volume stabilizing at the current level. After years of continuous decline, the volume of the gas turbine market in fiscal 2019 remained on the prior-year level, again being impacted by customer delays of large projects in Asia, Australia, particularly in China, and strong price pressure resulting from intense competition. Customers also showed restraint due to ongoing weak growth in demand for power, combined with uncertainty regarding regulatory developments. The gas turbine market is experiencing overcapacity among OEMs and EPC contractors, which is fostering market consolidation. In the market for large steam turbines for power generation, volume shrank further year-over-year from an already low basis of comparison due to an ongoing shift from coal-fired to gas-fired and renewable power generation, as well as to carbon emission regulation. We expect these developments to continue in fiscal 2020. In contrast, markets for industrial steam turbines were stable in fiscal 2019, and the market segment is expected to be flat in fiscal 2020. Oil and gas markets developed positively in fiscal 2019, driven by a recovery in liquefied natural gas. They are expected to grow again in fiscal 2020, driven by the liquefied natural gas and upstream markets. Both markets for offshore and onshore exploration are anticipated to recover further based on a growing number of expected project approvals. Pipelines, downstream, and oil and gas-related markets are expected to remain stable in fiscal 2020.
