Strategic aspects of cooperation between

telecommunication and the energy sector –

perspectives from a DSO

Update from the Radio Spectrum of the

European Utility Telecom Council (EUTC)



Why electricity is so important in today’s society

Many national services and infrastructures rely on electricity: Industrial processes

Public transport

-one day private transport



A critical need for communications

Therefore utilities (especially DSOs) need telecommunications services that are :

Reliable Secure

Cost effective

Resilient Storm

Efficient SCADA/RTUs(data) and


Use of commercial networks vs. private networks

When utility requirements are close to the target audience of the telcos, it’s an easy choice

But when additional requirements are added for mission critical services, e.g.:

Coverage (important RTUs even in remote areas) Latency (for safety reasons)

Security (physical separation of critical data)

Resilience (to escape the vicious circle “no electricity/no telecommunications”)



Why spectrum? And what has to be done?

EUTC is working with the Commercial Communication providers, the

European Commission, National and Regional Agencies and projects such as ENERGISE to ensure an understanding of the needs and communication requirements of Utilities such that the most efficient commercial and

technical use of private and commercial solutions can be delivered for utility use.

Even if some utilities can deploy fibre networks, the cost-effectiveness and coverage requirements tip the scales in favour of wireless communications. Spectrum is needed.

Utilities are not recognised users of spectrum by the World Radio Council, a situation EUTC and its global family (UTC, AUTC, UTCC, UTCLA) are trying to rectify.


First steps in the recognition of utilities as

spectrum user

We currently have a Technical Report draft in the ETSI standardization

process, hosted by ERM-TGDMR : DTR/ERM-TGDMR-340 Smart Grid

Systems suitable for Utility Operations, and spectrum requirements.

The TR highlights:

Systems suitable for Smart Grids, e.g. to include at least the following essential criteria:

very high link availability >30km link lengths

priority access, stringent end-to-end latency requirements coverage to remote / unpopulated areas

licensed self-managed spectrum in a variety of bands (e.g. 400 MHz [including the FIXED / MOBILE sub-bands that have a European Common Allocation for Mobile systems and] 1400 / 1500 MHz)

ability for Best Practice resilient operation.

The essential requirements for systems suitable for other Utility Operations radio systems.


Enedis’ approach for cooperation towards



Enedis in a few figures

1.3 million km of lines

MV: 700 000 km

LV: 600 000 km

35 million customers

39 000 employees



Wired communications

For wired communications, Enedis rely on commercial operators services

A few exceptions :

Linky smart meters communicate between customer homes and MV/LV substations in PLC

In Paris, a copper/FO networks is operated by Enedis No plan (even long term) to deploy a FO network

But we can facilitate the deployment of fibre optics by offering to use our poles and ducts

THD project


Wireless communication

We operate a private 70 MHZ radio network in addition to the mobile phones used by our technicians on the field

Today, it is the key to escape the no “electricity/no telecommunications” vicious circle

It also supports the control/command of 20 000+ legacy RTUs But it can’t accommodate the new devices/RTUs

IP based protocols More verbose

Possible cyber-attacks: remote administration is required New smart grid operations



Wireless communication

The default choice will be operated M2M services

But how can we make it more reliable and more cost-effective ? We are now studying the benefits of eUICC

If the SIM card is not owned by the operator, we can lower the costs of reversibility (costs we may have to pay each time we sign a new contract)

It should allow a dynamic MNO switching when the main MNO is down


Cooperation with telcos in crisis management


The dialogue can take place at different levels

Between “vitally important industries”, in state-led processes In advance, to prepare strategic plans (e.g. river Seine flooding in Paris)

In emergency, to get the job done

Between large nationwide network operators To exchange best practices

Of course we already share some radio sites Between client and supplier



Food for thoughts for the “Co-operation in critical

operation status” working group

Can an operator (with its commercial network) and a utility (with its private network) be partners in the creation of a ‘sovereign’ PPDR network?

Can win-win procedures be established for a quicker resolution of crisis situations?

Installation of mobile generators for the most useful BTS

Deployment of mobile BTS where needed to restore the grid Can a utility negotiate a ‘premium’ service?

Warranty for no SPOF between normal and backup communication for most critical sites

Priority for utility critical communications
