Information Technology

Significant benefits were achieved in 2010 as a result of information and communication technology projects and innovation at Terna. The following objectives were achieved:

1. Benefits for business deriving from the completion of important initiatives

Enhancement of National Electricity System security – National Electricity System security was enhanced through a series of interventions to improve the effectiveness of the control and operation system as regards the observed grid perimeter (extended to around 2,000 distribution stations) and real-time output plants (with more
than 3,000 MW added).
Defence system effectiveness was also improved through the extension of disconnectable loads to distribution stations through the new emergency control panel (ECP) system, and extension of monitoring to additional events at hubs limited to the Calabro ring and the northeast-northwest backbone.

  • Dispatching incentives – Following AEEG Resolution no. 206/08, which encouraged Terna to reduce the volume of energy procured on the Ancillary Services Market, significant work was undertaken to improve IT support instruments used for real-time planning and dispatch operations. Specific tools have been consolidated for the optimised use of strategic storage and Optimal Power Flow tools in the process of the tertiary regulation of production plants. Additionally, NTC (Net Transfer Capacity) for 2010 has been redefined in order to improve the management of the interconnection, with specific reference to low load periods, and the basis for regulation services has been extended.
  • Regulatory adjustments - The application platform supporting the Ancillary Services Market, both during the programming stage and in real time, has been reviewed following Resolution ARG/elt 211/10. On 31 December 2010, the computer systems were adjusted at the time of instituting the new intra-day markets both of energy and dispatching services. The adaptation of the systems, giving rise to an Authority obligation, has made the new market rules operative, allowing operators to adjust their input programme and Terna to refine programming of services delivered at several stages throughout the flow day.

The application platform for market settlement has been reviewed following said resolution. The systems going towards invoicing the amounts of the Ancillary Services Market have been adapted in time for the first invoicing of the new market structure. Finally, the issue during the period of the GAUDÌ system is worthy of note: a consolidated record of plants in production of all sizes and on all voltage levels. As per the Authority guidelines, the system represents the consolidated record of the production system, allowing for its services to be supplied to the benefit of all sector operators.

2. Enhancement of the telecommunications infrastructure as a key asset for National Transmission Grid management

  • TLC infrastructure – In 2010, the optic fibre telecommunications grid infrastructure services owned by Terna have been consolidated. The services activated relate to the control and operation system and the video-surveillance of the power stations. The migration of the Defence Systems grid to the new owned infrastructure has also been completed, with significant benefits in terms of reliability and performance.
  • Perimeter security – The efficiency of the firewall security systems has been further improved, thanks to the completion of the installation of the firewall systems at the power stations. The redundancy of intrusion prevention tools on the management grid for the identification of potentially dangerous traffic.

Managerial information technology and services to people

In 2010, the technologies at the calculation rooms of the 8 territorial operative areas of the Parent, now obsolete, were consolidated and renewed. Again with a view to renewal, the new calculation room was created at the Pero (MI) Terna office, technology was introduced to monitor the technological infrastructures with a view to guaranteeing continued availability of the services supplied and there was proactive identification of failures to infrastructures.
