The Annual Garrad Hassan Lecture 2016: Energy Storage, Renewables and National Electricity Systems

The 2016 Annual Garrad Hassan Lecture on Energy Storage, Renewable and National Electricity Systems with talk to be given by Paul Gardner, is to be hosted at the University of Bristol on 3rd November from 5:15-6:15pm at the Pugsley Lecture Theatre, Queen's Building.


Energy storage has become a hot topic, especially for the variable renewables, and especially using batteries: the casual observer could get the impression that battery options alone are both necessary and sufficient for economic integration of very large quantities of wind and solar generation in national electricity systems.

This lecture will consider the pros and cons of competing energy storage technologies for renewables-integration issues, but will also consider more broadly the other functions or services that can be provided by energy storage, and also the other available ‘flexibility’ options which compete with energy storage to provide these services. What cost reductions and technical advances can we expect, and how will these affect the use of energy storage technologies?

The presentation will also cover the ‘new’ problems associated with very deep decarbonisation of energy systems, in particular the options for energy storage on seasonal timescales.


Paul Gardner trained as an electrical engineer and has worked in renewables since 1984. He led the electrical engineering group at Garrad Hassan, the world’s largest independent technical consultancy for renewables, now part of DNV GL. His experience included wind turbine electrical systems, network connections, and grid integration issues. Subsequently he joined the Strategy and Policy Studies Group at DNV GL, providing strategic and market advice to government bodies, NGOs, established companies in the renewables industries, and new entrants.

He is now global Segment Leader for Energy Storage, responsible for co-ordinating DNV GL's activities in Energy Storage, including integration of renewable energies, electricity grid applications, distributed and isolated energy supply, heat, electric vehicles, and electric marine propulsion.
