Something to bare in mind when you're looking at both of those is the price is highly dependent on a number of factors;

- Type of generation, looking at the NY data they have a huge hydro generation, obviously the UK grid has much less of that

- Time of day, the Elexon graph is showing you the system price per 30 minute settlement period. You can see that some of those periods weren't anywhere near what you're quoting (there was literally a period where the system price was 0£ in the last 24h). https://www.bmreports.com/bmrs/?q=balancing/systemsellbuypri... makes the volatility much more obvious.

- The weather, it plays a big part in the system price due to price disparity of renewables (commonly wind in the UK grid) compared to oil based and gas generation.

- The interconnect, the UK grid has interconnectors to the EU grid so there's some price impact from that
