Energy Performance Modernization: Turning Energy Consumption into Energy Efficiency

Voith has won an order from Slovenské elektrárne a.s., Slovakia’s largest electricity producer, to modernize two units at the Čierny Váh pumped-storage power plant. The contract was signed on October 27, 2026; GE Energy Power Conversion GmbH (GE Vernova) is participating as an additional technology partner.

With the next generation of Sinamics G drives, Siemens introduces a unified drive portfolio for continuous-motion applications. It comprises the new Sinamics G200, G210C, G210 and G210X as well as the Sinamics G220, first introduced in 2023, and offers a consistent approach to engineering and operation.

When it comes to purchasing industrial equipment, few principles appear more straightforward than getting the best price. Yet when applied to pumping systems, an excessive focus on initial purchase cost can ultimately prove to be a false economy.

At its San Cesario sul Panaro plant, Zenit Italia S.r.l. is implementing a new energy efficiency and ecological transition plan.

Seven pump selection errors that stay invisible at quote time – from NPSH margins to viscosity correction. The free VSX whitepaper “Best Practices for Avoiding Hydraulic Pump Selection Errors” shows engineering and sales teams how to spot them early, what they cost and which standards apply. Includes an 8-point pre-selection checklist.

In a contributed article, Adrian van Wyk, Managing Director of Referro Systems, explains why purchase price, motor power and flow curves are losing weight in pump selection. He points to lifecycle cost, efficiency across the actual operating range and the limits of predictive maintenance without matching maintenance processes.
