ANDRITZ has received a new contract to modernize the first four units, B1–B4, at Rock Island Powerhouse 1.
ANDRITZ's proposed turbine design increases capacity, at lower heads, and boosts unit efficiency, providing incremental value to Chelan PUD. Another benefit of the new runners is the fish-friendly design, reducing the number of blades from six to four and reducing the risk of blade strike by a factor of 33%.

At the Lower Monumental Dam hydropower plant turbine unit #1 experienced a runner hub linkage failure. The rehabilitation work replaced internal hub linkage components requiring disassembly of the main unit and turbine runner. For unit#1 were also supplied new stator winding and a stator core.

Repairs also included cavitation repair to unit #1 blades, hub and discharge ring as well as repair of cavitation damage to the unit #2 runner. Following the repair, both runners will work as completely functional double-regulated Kaplan run­ners.

Atlanta has intensified its efforts to provide safe and stable supplies of potable water for its citizens. Bellwood quarry – northwest of Atlanta’s downtown district – is going to become one of the biggest water storage facilities in the country, ­storing some 2.4 billion US gallons of water (9.1 billion liters) as part of this program.
Converting a 300 ft (91.4 m) deep ­quarry into a water storage facility and recreation area includes blasting two circular pump station shafts near the quarry, one 35 ft (10.7 m) diameter and 200 ft (61 m) deep and the second with a 20 ft (10.6 m) diameter and 300 ft (91.4 m) deep. Five further 6.3 ft (1.9 m) diameter pump shafts are to be constructed, along with a new power substation and various improvements to existing infrastructure.
