Achieving a primary frequency response with CCGT steam turbines
05 November, 2002
Genelba power plant has been offering primary frequency regulation (PFR) to the highly competitive Argentina electricity market without sacrificing gas turbine capacity. During two years of operation this innovative approach, entirely realised by plant staff, has proved effective and lucrative. Benjamín Guzmán and Jorge Vugdelija, PECOM Energía S.A, Argentina

Air cooling in a dry state

Does competition rule out CO2 capture?
05 November, 2002
The Kyoto protocol demands major reductions in emissions of greenhouse gases such as CO2, and the technology exists to achieve full compliance, but electricity generators and traders protest that competition has already driven prices too low for them survive even without the additional costs of separation and sequestration.

The record-breaking Italy-Greece HVDC link
05 October, 2002
The new Italy-Greece HVDC link is at 1000m the deepest submarine link in existence, and includes one of the longest underground sections in the world. Proving it involved an exhaustive series of factory and site tests which could be compared to main performance criteria reported during the commissioning stage, a process described in a paper delivered to Cigré Session 2002, Paris, in August this year.
