Zonal Pricing Was Rejected. But Location Still Matters More Than Ever.
Government decided not to divide Great Britain into separate wholesale electricity price zones, confirming its Review of Electricity Market Arrangements would retain a single national wholesale market instead.
That avoided one enormous market reform. It didn't make every location equally attractive for generation, storage or demand. Electricity may retain a national wholesale price, but the network itself stubbornly remains geographical.
What zonal pricing would have done
The proposal would have introduced different wholesale prices in different regions, giving a much stronger locational signal to generation, demand and investment - broadly, cheaper prices where power is abundant relative to local demand, and higher prices where it's scarce or constrained.
Why it was controversial
Supporters argued it would drive more efficient dispatch, reduce the cost of managing network constraints, and encourage generation and demand to locate more sensibly. Opponents - including much of the renewables investment community - pointed to investment uncertainty, the risk of regional price disparities, real implementation complexity, financing risk for projects already committed under the existing structure, and a difficult transition. Government ultimately concluded the disruption and complexity outweighed the benefits, particularly given the risk to near-term investment.
What the rejection actually means
There's no imminent regional wholesale price revolution. But connection location, import and export capacity, network charging, curtailment exposure and flexibility opportunities all continue to vary significantly by location, national wholesale price notwithstanding.
Where location already shows up
DNO reinforcement requirements, available connection capacity, network charges, curtailment risk, local flexibility opportunities, private wire feasibility, and simple proximity between generation and demand all still depend heavily on where a site actually sits - none of that was ever determined by the wholesale pricing structure in the first place.
Practical implications
Assessing connection position, network constraints, export assumptions and site geography properly before choosing equipment and committing capital remains just as important as it always was. A national wholesale price was never the only thing that made one site's economics different from another's.
The policy question isn't finished
Network charging reform, connection queue management and investment signals continue to evolve independently of the zonal pricing decision. Location's commercial relevance isn't going away - it's simply being managed through different mechanisms than a fully zonal market would have used.
Zonal pricing may have been rejected, but the underlying lesson survived: where electricity is generated, stored and consumed increasingly matters commercially. The price is national. The opportunity isn't. If location-specific factors are shaping - or should be shaping - a project's economics, get in touch.
