The article also explained the increasing focus on
environmental concerns and methods for achieving
a strong eco-design approach.
✔✔ highly digitized equipment (compliance with low-

✔✔ Use of large battery energy storage for grid purposes: A

power instrument transformers and the IEC 61850
protocol for the use of sensors to perform monitoring)
✔✔ easy maintenance.
RTE began the Innovation Partnership to pursue longterm research, development, and performance tests and
acquire pilot sites for applying new concepts and products.
Industrial partners will be selected according to their innovative technologies and abilities to maintain a research and
sustainable development effort in the HV-extra-HV substation-equipment domain. The research phase will last for
a maximum of two years. The development and pilot-test
phase will take no more than three years.

pilot project will be conducted to validate the use of largesize batteries that manage intermittent congestion resulting from renewable-energy sources. These batteries, located in appropriate substations of the grid, will be charged to
accommodate the peak generation from renewables. The
technical challenge is to implement a control system able
to automatically optimize each battery's state of charge to
avoid congestion in preventive and curative modes without
any action from the power-system operators.
✔✔ SF6-free substations: Widely used for 40 years as the
best and least expensive insulator gas for GISs and
circuit breakers, SF6 is now recognized for its impact
on GW when leaks occur in aging components. RTE
commissioned its first 63-kV alternative GIS in 2019
and launched a European innovation-partnership purchasing procedure to design and test other SF6-free
solutions for substations from 63 through 400 kV.

Summary
This article presented a series of innovations at RTE,
explaining why they were developed, how they were implemented, and possible further work to be done. It described
case study solutions where taking advantage of existing grid
capabilities when building new lines proved premature in
some cases, expensive in others, and always difficult. The
article also explained the increasing focus on environmental concerns and methods for achieving a strong eco-design
approach. The lessons learned are as follows:
✔✔ DLR: These technologies are not new, but to be successfully implemented, their introduction requires
caution and a thorough analysis of conditions. Accurately measuring wind speeds and temperatures along
critical spans in real time enables potential increases of
the maximum permissible capacity for OLs. The same
idea can be applied to underground cable circuits.
✔✔ Digitizing OLs and underground cables: By incorporating power electronics, sensors, telecommunication
equipment (such as optical fibers and Global System
for Mobile Communications standards), and centralized computation, equipment can be operated in the
most efficient way. This is particularly useful when
grid flows are highly variable, possibly because of intermittent renewable-energy sources.
✔✔ SmartModules: These devices, when installed on
OHLs, hold the promise of increasing the overall
grid's power-flow capabilities in a smart, flexible, and
economic manner. SmartModules may provide an efficient way to solve congestion issues on particular
circuits by controlling the flow through a mix of grid
and telecom technology. Their first demonstration
was successful and found to be of great value.
