Sometimes the big batts (in particular) mention W's not Wh's as they may be able to deliver all energy in less than one hour, so their Wh rating may actually be lower than their W rating, though normally it would be the other way round.
On this occasion the article mentions (as you spotted) the sum calculation of the batts being deployed, and those ratings relate to Wh's, as you concluded.

The article simply covered storage trials on two levels of deployment scale, domestic & grid, and in both cases the variability issues resulting from demand changes and renewable technology generation is addressed. This can only be seen as a positive move, whether you have a bias for or against particular renewable technologies, or even have no particular viewpoint at all ....

I am surprised Z hasn't sent you a PM so you could correct the post
As you are such a stickler for the correct terminology I was referring to the fact that there were 7 batteries.
It is not 'sloppy journalism' at all! In that context kW and MW is the correct terminology. Also where did Exiled Tyke conclude it was Wh's(sic).
Suggest you read up on Flow batteries!0 -

With what are you agreeing?

That did cross my mind, but I assumed (clearly wrongly) that even you wouldn't be that petty.
Batteries are typically quoted as the sum of their parts, rather than the individual packs or cells. In this case I've clearly combined a number of batteries into the sum of their deployment. I do not believe I have committed a crime, nor given any advice that could potentially cause significant financial loss to readers.
If my stating the sum, so offends you, then I apologise. But also thank you sincerely for raising the issue, and giving me a good laugh.

Done some reading as you suggest, but it's not good news for you I'm afraid. The batteries are actually called 15kW-240kWh, giving a power rating of 105kW and a storage sum of 1.68MWh (7x240kWh).
So, as I said, sloppy journalism. Anything else I should read up on?

Edit: BTW, my assumption that ET had spotted it was MWh not MW was just a loose assumption. I wasn't going to leave it in, but thought I'd see if 'anyone' would get upset and complain again. M.Mart.

UK solar eclipses coal power over month for first timeSolar power in the UK produced more electricity than coal across the whole of May, the first ever month to pass the milestone, according to research by analysts at Carbon Brief. Solar panels generated 50% more electricity than the fossil fuel across the month, as days lengthened and coal use fell. Solar generated an estimated 1,336 gigawatt hours (GWh) of electricity in May, compared to 893GWh output from coal.
Not sure how June will compare. I think some of the coal fleet had problems during May. Coal seems closer to 3GW these days, so it will take 72GWh PV days to top that, with PV so far in June varying from as low as 16GWh to 62GWh per day.

HiWho would ever argue against the development of battery storage?
Undoubtedly, at some time you'll find a way to bring unnecessary negativity and disruptive pettiness to storage related threads and discussions (such as the case in hand) as that's what you increasingly tend to do whenever distributed generation technologies are involved .... ..... other's will simply discuss the pros and cons of the various battery technologies, wait for affordability conditions to be met, make a sourcing decision and buy ...
Daytime PV + battery storage + offpeak grid top-up = grid smoothing .... who'd have thought it, a workable solution to the evening peak which exposes smart-metering to be an utterly outdated concept, but the best part is that we'll not need to hear the same-old regurgitated rubbish about renewables and demand peaks ... bliss, can't wait!

China has put a cap limit on PV rollout for 2016 ........ at 18.1GWp :eek:

Momentum in the US is still building fast:
GTM: Solar accounts for 64% of all new electricity online in US for Q1 2016*In the first quarter of 2016, the US installed 1,665MW of solar PV, with 14.5GW of installations forecast by GTM Research and the Solar Energy Industries Association (SEIA) for 2016 – down by 1.5GW than was previously predicted.
Nevertheless, solar beat out coal, natural gas and nuclear installation figures combined; accounting for 64% of all new electric generating capacity online for Q1 2016.
* Note, that's capacity, not generation.
