Natural disaster response plan
Iceland’s electricity network is in many ways its lifeline. Response plans to any type of disaster must therefore be well defined. The objective is to ensure the secure operation of the electricity network which acts as the foundation for the working community and national economy.
Landsvirkjun’s emergency management team was activated on the 16th of August, 2014 when the Department of Civil Protection and Emergency Management, under the auspices of the National Commissioner of the Icelandic Police, declared the country to be at the ‘alert phase’ as a result of volcanic activity at Bárðarbunga. Regular meetings have been held since then to assess and disseminate information on the status of volcanic activity to the north of the Vatnajökull Glacier.
Landsvirkjun’s response plan for natural disasters includes seismic activity, ash fall and floods of various sizes. Response plans were updated as a result of the activity at Holuhraun and Bárðarbunga and preparation measures were undertaken for possible scenarios which could be realised as a result of the activity. A decision was made to improve flood protection at Hágöngur in order to prevent a dam break in a large-scale flood. Ventilation systems were checked at all power stations in the Þjórsá and Tungnaá river catchment areas in case of extensive ash fall and action plans for protecting the stations in case of flooding were also reviewed.
Powel Nimbus energy steering system
Landsvirkjun invested in a new production planning system, provided by the Norwegian company Powel at the end of 2012. The system was implemented this year and is called Nimbus. The main role of the new system is the development of planning/estimates for production steering based on client estimates, reservoir status, inflow forecasts and maintenance schedules. Nimbus also stores water and production data as well as facilitating the systematic analysis and forecasting of water management. The new system will improve water utilisation at the power stations and increase the effectiveness of production steering.
