What is dispatching?
Electricity cannot be stored. It is therefore necessary to continuously produce the quantity of energy required by all consumers (families and industries) and deliver it to the national transmission grid so that electricity supply and demand are always balanced, therefore guaranteeing continuity and safety of the service supplied. Management of this energy flow along the grid is known as dispatching.
Who owns the transmission grid?
Terna is the main owner of the National Electricity Transmission Grid; it owns over 72,900 km of high voltage lines throughout the national territory and 871 transforming and switching stations.
What is the activity carried out by National Control Center?
It ensures the operation of the national electricity system in conditions of utmost safety in order to guarantee continuity and quality in the electricity service. For this purpose, the National Control Center continuously acquires all the data and information on the situation of the electricity system and, in relation to the electricity demand trend, takes action to guarantee a good balance between demand and supply.
What is the National Transmission Grid Development Plan?
The National Transmission Grid Development Plan is a document that Terna draws up each year and which contains all the development activity undertaken, or to be undertaken in the ten-year period involved, on the Transmission Grid. For every region, activity is grouped on the basis of voltage levels and according to types (stations, joints and long-distance power lines). Once drawn up, the Plan is then submitted to the interested Regions and to the Ministry for Economic Development that verifies its compliance with existing laws, with its strategic and operative guidelines and with the objectives deriving from the Concession.
What is an interconnection?
Electricity exchanges among neighboring countries (interconnection) play a very important role in the European policies for establishing a single market. At present, the Italian electricity grid is “interconnected” with the grids of neighboring countries through 25 lines that connect it with France, Corsica, Switzerland, Austria, Slovenia, Greece and Montenegro.
When did the peak electricity demand occur?
60,400 MW is the new historical record for maximum power demand on the Italian electricity grid. The figure, registered on Wednesday, July 22, 2015, at 3 pm, in a day characterized by a very high temperature, is 3,578 megawatt higher than the former historical winter record (56,822 MW, December 18, 2007).
Which is the body in charge of preparing and distributing statistics on the national electricity system?
Terna’s Statistical Office, part of the Sistan (National Statistical System), has the statutory task of drafting the official statistics for the entire national electricity sector and is therefore also responsible for our country for disseminating official statistical information to international bodies such as Eurostat, IEA, OCSE, the UN.

- a New User, that holds no contract relations with Terna nor Connection requests to the NTG.
What does it mean to request a connection to Terna’s grid?
Requesting a connection to the National Electricity Transmission Grid means expecting to input/withdraw energy from the Italian HV or EHV electricity system. For all plants with a power exceeding 10,000 kW, connection requests must be submitted to Terna.
In which area of MyTerna portal can a connection request to the NTG be submitted?
In the portal section “My services” the area “Managing connection requests” is present. Within this area, the user can submit a connection request to the NTG by selecting “New connection request”: a specific form must then be filled out and the documents required must be attached.
How do I obtain grid connection?
The connection procedure starts with a request that must be filled out on My Terna portal, indicating the data of the applicant and of the plant to be connected to the NTG. Following this, Terna prepares an estimate that identifies the works on the NTG that are necessary for the connection, together with relative timeframes and costs. On the basis of this estimate, a project of the works to be implemented on the NTG must be drafted; this project will then have to be authorized by the authorities in charge, as well as the user’s plant. After having obtained the authorization, still through the portal, a Minimum Detailed Technical Solution is requested, that Terna drafts and sends to the user. Lastly, the connection contract can be entered into.
Is the entire connection procedure managed on MyTerna portal?
Yes, with the exception for the project and the contract that will be managed on hardcopies. All other obligations included in the file are made online through the portal functions (ex. Notices regarding progress of the authorization procedure, notices on work progress, acceptance of the estimate – SMTG – and of the detailed solution - STMD).
How are the works for connecting to the NTG authorized?
NTG works for connection of a plant to the NTG are authorized in two ways:
- for production plants from renewable sources, a single procedure is carried out for the production plant and the NTG connection, pursuant to Legislative Decree no. 387/03;
- for other types of plants, Terna may autonomously carry out the authorization procedure for the NTG works necessary for the connection, according to Law no. L. 239/04.
In which cases should the 30% connection fee be paid upon the acceptance of the connection estimate?
The payment of 30% of the connection fee upon the acceptance of the connection estimate should only and exclusively be paid for connection requests submitted after January 1, 2011, or any power variation in requests that were already submitted.

What is RAB?
RAB, Regulated Asset Base, is the net value of the invested capital of a regulated company, calculated based on the rules defined by the Regulatory Authority for Energy, Networks and the Environment (ARERA) in order to determine revenues. It is re-evaluated annually based on the ISTAT data on the deflator variation of the gross fixed capital and is updated based on investments and disposals.
What is WACC?
What does the concession agreement for transmission and dispatching say? Article 1 of the Bersani Decree (Legislative Decree 79/1999) establishes that, among other things, electricity transmission and dispatching activities are reserved for the State and granted in concession to Terna, who also owns the assets of the Italian National Transmission Grid. With the subsequent the Ministry of Production Activities Decree (20 April 2005), as amended with the Ministry of Economic Development Decree(15 December 2010), the transmission and dispatching of electricity throughout Italy was granted in concession to Terna until 2030.
WACC (Weighted Average Cost of Capital) is the weighted average cost of capital. The methods for determining and updating the WACC, which can also be defined as the rate of return on the invested capital, are established by a resolution specified by ARERA. For the 2016-2018 period, the regulatory WACC for electricity transmission service is fixed at 5.3%, pre-tax.
