The European Network Codes and Guidelines entered into force about ten years ago. As markets and power system needs have evolved since then, the time has come for updating them.
There were no previous grid code requirements for grid energy storage, and it has become necessary to specify some requirements as storage technology has developed and the number of grid energy storage facilities has increased.
Fingrid’s customer organisations are working to implement the requirements of the EU network code on electricity emergency and restoration. The 24-hour operability requirement and automatic under-frequency load shedding system must be implemented by December 2022.
Fingrid is working with Leppäkosken Sähkö to test a fuel cell solution that can charge the substation’s batteries, thereby safeguarding its critical functions in the event of a disturbance. Fuel cells generate energy from a mixture of water and methanol.
The President of the Republic of Finland bestowed the title of Professor on Ritva Hirvonen, Fingrid’s Planning Manager, on 19 December 2019. The honorary title of Professor is awarded by the state in recognition of talented practitioners of the sciences and arts.
The Network Code for Emergency and Restoration (NC ER) specifies the common requirements for handling emergency, blackout and restoration states in the power system. NC ER harmonises the operation of power systems throughout the EU and with Third Countries.
“Fingrid collects customer feedback via several channels. A good meter and trend indicator is the customer feedback survey conducted every year; respondents comprise around 200 customers. Continuous feedback recorded in the customer information system is collected from routine customer encounters,” says Jussi Jyrinsalo, Fingrid’s Senior Vice President responsible for customer relationships.
The Specifications for the Operational Performance of Power-generating Facilities (VJV) will be updated next year. The EU’s network code for the connection of generators (NC RfG) will become part of Fingrid’s requirements.
The Network Code for Emergency and Restoration harmonises the actions of transmission system operators during an electricity system disturbance.
Fingrid’s general connection terms will be renewed this year. There is a need to update the current connection terms to respond to today’s requirements.
