Battery energy storage will be the key to energy transition – find out how

The market for battery energy storage is estimated to grow to $10.84bn in 2026. The fall in battery technology prices and the increasing need for grid stability are just two reasons GlobalData have predicted for this growth, with the integration of renewable power holding significant sway over the power market. Over the last decade, various new digital and smart technologies have been integrated, with countries aggressively promoting the modernization of grids, enhancing the grids’ capability to meet present and future requirements. As part of the effort, batteries are being deployed for a wide range of uses. A few such uses include aiding smart grids, integrating renewables, and creating responsive electricity markets.

Deriner Dam is the highest dam in Turkey, with a height of 249m. The double-curvature concrete arch dam is located on the Coruh River near Artvin province in the north-eastern part of Turkey.

The underground powerhouse near the dam houses four units, with an overall capacity of 670MW. Commissioned in 2013, the powerhouse annually generates 2.118GWh of electricity.

“The project is owned by Turkey’s State Hydraulics Works (DSI) and was constructed by a consortium led by ERG.”

The project is owned by Turkey’s State Hydraulics Works (DSI). The power plant was constructed by a consortium led by ERG, and required an estimated investment of $1.39m.

Construction on the dam began in 1998. The project work involved constructing the dam’s body, rock excavation, diversion tunnel, underground powerhouse, overflow spillways, access roads and internal roads.

The concreting work began in 2005 after the completion of excavation process, but was stopped between 2007 and 2008 due to lack of funding. However, the work was resumed in the last quarter of 2008 and completed in February 2012.

The hydroelectric power plant (HEPP)

The HEPP is located on the right bank of the river near the dam. The completely underground powerhouse features four vertical Francis turbines and generates 2.118GWh of electrical energy annually.

“The electrical energy generated by the plant amounts to 1.1% of the total energy production in Turkey.”

The electrical energy generated by the plant amounts to 1.1% of the total energy production in Turkey.

The powerhouse is 20m-wide, 126m-long and 45m-high. The turbines in the plant are fed with water through a 9m-diameter penstock. Water from the turbines is then exited through 74m-long tunnels.

The Deriner double-curvature concrete arch dam

The Deriner dam is a double-curvature concrete arch dam. It is 249m high from the foundation and 202m from the river bed and has a crest elevation of about 397m. The dam has a concrete volume of 3.5 million cubic metres.

The diversion tunnel is 898.14m-long and has a capacity of 1.804 cubic metres a second (cusec).

The overflow spillway has a capacity of 2.25cusec while the orifice spillway has a capacity of 7cusec.

Key players in the Deriner dam project

Turkey’s State Hydraulics Works (DSI) owns the project. A consortium comprising ERG Construction, Technopromexport, Stucky, ALSTOM, Sulzer Hydro and Hydro Vevey was responsible for the construction of the project.

The consortium of Poyry (formerly Electrowatt Engineering) and Dolsar Engineering designed the dam and the powerhouse under an approximately $24m contract. The consortium was also responsible for providing quality assurance throughout the project.

Construction work and components of the project

The funding for the project was attained in 1997 and construction began in 1998.

The excavation and construction of the dam’s foundation necessitated a diversion of Coruh River, which was completed in 2005. The diversion was done through a horseshoe cross-section tunnel on the right bank.

Future Power Technology Magazine: Water Power Edition

With a host of new technologies riding the wave of innovation and investment, marine and hydro power are catching up with the major renewables.


The Deriner site consists mainly of granodiorite rock with a certain amount of diabase dykes. The decompressed and heavily jointed rocks existent in the upper layer necessitated a huge amount of excavation to be undertaken.

The excavation work was carried out by drilling and blasting using the pre-splitting method. The initial sections of the foundation were, however, excavated using a controlled blasting method. Pre-stressed anchors were used in some cases.

Natural slopes totalling 430m in height from the right bank, 480m in height from the uppermost part of the left bank, 29 berms at the right bank and 33 berms at the left bank were excavated.

Associated infrastructure such as roads, tunnels and bridges were also constructed as part of the project.
