Times and technologies change, but our passion is always there. №33 / 2019 HYDRONEWS 3 Solving the challenges of the hydropower market Dear Business Friends, The energy market – and the hydropower indus- try especially – is facing many challenges with the growing demand for “base load renewables” and aging of much of the existing hydropower fleet. As a result, new strategies are needed for success- ful hydro asset management and operation. One solution to reduce costs and improve operations is maintenance optimization to increase revenues. The new Metris DiOMera Platform, developed by ANDRITZ, is addressing these topics. Among recent Wolfgang Semper Harald Heber project successes are the latest orders for Metris DiOMera, coming from the PresAGHO project in South America and Cerro del Águila in Peru. At a time when baseload power generation from fossil resources has to be replaced by a carbon-free renewable energy-based alternative, large-scale energy hybrid solutions offer a vital approach for the future. Hybrid solutions combine two or more power generation technologies with at least one renewable energy source, as well as a power and energy storage system. The Hatta project in Dubai is proof that ANDRITZ is a competent global partner for this evolving market. In addition to our large-scale hybrids, ANDRITZ has also developed a dedicated hybrid solution, which combines a battery with a hydropower unit – “HyBaTec”. It increases hydropower asset lifetime by reduc- ing mechanical stresses, triggers additional revenues by enabling participation in the short-term energy market, and opens up further opportunities to shift larger energy demands over the course of a day. Along with these new technical solutions, several large project contracts have been recently awarded or are actively under construction. Major developments such as Xayaburi in Lao PDR, Laúca in Angola, Murkraftwerk Graz in Austria, or Hoa Binh in Vietnam are some highlights. There are also many interest- ing opportunities emerging for our small and mini hydropower systems in this growing market. The energy industry is certainly facing many challenges, but with our technical abilities, the depth of our experience and our highly motivated staff, ANDRITZ is confidently looking forward to the future.

With a capacity of approximately mix to 7% by 2020, 25% by 2030, and 75% by 2050. To 200 m3/s and partially lined with steel, the tunnel is a key achieve this ambitious target the Dubai Energy and feature of the new Hatta Pumped Storage Power Plant. Water Authority (DEWA) decided to increase the power generation contribution from sources like photovoltaic solar and wind. But, in addition, to also create the nec- essary energy storage capacity required to balance these volatile renewable energy sources. Further investigation determined that in regions with hot ambient conditions, pumped storage technology is superior to battery technology. Batteries are sen- sitive to heat and, as a result, a utility-scale battery storage facility would require a tremendous amount of electricity for cooling purposes. ––– HATTA DUBAI, ––– THE CONCEPT Near the community of Hatta, approximately 140 km southeast of Dubai in the Hajar Mountains on the north- ern border with the Sultanate of Oman, there is an exist- ing reservoir created by the Sadd Hatta Al Awwal Dam. Together with the French consultant EDF (Électricité de NEW PROJECTS NEW France), DEWA developed a concept to create a new №33 / 2019 HYDRONEWS 7 HYDRO POWER FROM THE DESERT “One third of the Earth’s surface from the French consultant Artelia, the consortium is arid or semi-arid.

It will host two pump turbine and motor-generator units with a capacity of 125 MW each. Capable of producing a total net power of 250 MW over a six-hour generation cycle in turbine mode and a 7.4-hour storage cycle in pumping mode, the project provides an overall storage capacity of some 1,500 MWh. Due to the relatively limited reservoir capacities, the available head will vary significantly, changing between 175 and 125 m during the charge-discharge HATTA DUBAI, ––– cycle. To overcome this large head variation while keeping the units running at a high efficiency over the complete cycle, both pump turbine units are equipped with double-fed asynchronous motor-generators. They allow the units to operate at variable speed.
