“Black Start” is the process by which the National Electricity Transmission System (NETS) would be recovered following a total system collapse. This is a not uncommon occurrence in some regions of the world but thankfully) unheard of in the UK; that does not mean we should not plan for such an eventuality.

However, the current approach, which requires the constant availability of a thermal plant on hot standby, is costly in both environmental and financial terms (around £50 million annually).

Energy is becoming more distributed and localised. We’re seeing the emergence of local energy communities, Microgrids and a whole plethora of potentially disruptive business models. To some this represents a challenge to their core business, to others it promises exciting new opportunities.

Today’s Distribution System Operators may fear the threat of grid defection. Even if there remain substantial income generating assets, these may become under-utilised and incrementally less profitable as new entrants cherry-pick the more profitable parts.

As the UK transitions to a new energy paradigm, incumbent players in the existing value chain, including gas network operators, face significant challenges to their current business models, and at Delta-ee we’re excited to help these companies to address these challenges.  

There are any number of proposals for a long-term energy system aimed at addressing the energy trilemma.  However, even where there is consensus as to the final shape of the energy system post 2050, there remains significant difference of opinion as to the most practical means of transitioning from today’s system to a fully sustainable one.
