    I thought it might be a good idea to have a thread for posting general news items that may be of interest.

    PV and the 'Solar in the news' thread attract a lot of interest, so here's a thread for all the other goings on.

    Good news:

    CO2 emissions stay same for third year in row – despite global economy growing
    Carbon dioxide emissions from energy have not increased for three years in a row even as the global economy grew, the International Energy Agency (IEA) said.

    Global emissions from the energy sector were 32.1bn tonnes in 2016, the same as the previous two years, while the economy grew 3.1%, the organisation said.

    Bad news, the proverbial supertanker is still going in the wrong direction, and too fast, but we've stopped accelerating.

    The pause in emissions growth was welcomed by the IEA, but it warned it was not enough to meet globally-agreed targets to limit temperature rises to below 2C above pre-industrial levels – considered to be the threshold for dangerous climate change.

    Energy transition to generate US$10 trillion in benefits by 2050 – IEA/IRENA

    The route to decarbonisation in the energy sector will create benefits of US$10 trillion every year by 2050, while requiring only US$1.8 trillion to implement, according to a new joint report from the International Energy Agency (IAE) and the International Renewable Energy Agency (IRENA).
    Costs of the energy transition up to 2050 are projected to reach US$29 trillion by 2050, roughly 0.4% of global GDP, but these costs are expected to then boost global GDP by 0.8% in the same period.

    What a load of Sh!t
    Nappy power plant converts tonnes of waste into energy

    http://www.bbc.co.uk/news/uk-england-birmingham-39333446

    A multi-million pound plant has opened in West Bromwich to convert tonnes of used nappies, sanitary protection and incontinence pads into fuel for power stations.
    On a similar note, I followed a tanker carrying human waste on my way to work this morning. It put a huge smile on my face for two reasons. Firstly, the number plate was P200 P00 , Secondly it had a sign on the back saying "This vehicle is carrying political promises".

    So good to see a company with a real sense of humour.

    Tory voters like PV and on-shore wind too, so it's hard to work out exactly who the government is trying to please by virtually destroying these two, cheap, industries?

    Tories favour solar and call on government to encourage further renewables deployment

    The report also concluded that the majority of Tory voters were proud of the UK’s historic support of climate and environmental initiatives, and 85% wanted the country to maintain renewable energy and energy efficiency targets post-Brexit, as these are currently set at EU level.

    This extended to a majority of those surveyed wanting the current government to afford further support to the deployment of renewables despite the raft of cuts enacted shortly after the party’s election victory in May 2015.

    Since then solar and onshore wind – the two cheapest renewable generation technologies according to the government’s advisory body, the Committee on Climate Change – have been subjected to various cuts in subsidies which have significantly stymied deployment.

    Update on this month's long anticipated (no? Just me then) CfD auction. Off-shore wind is still expected to join PV and on-shore wind by going cheaper than new nuclear, but 9 years sooner than expected:

    UK’s bet on offshore wind pays off as costs plunge

    “I wouldn’t be surprised if we saw a dramatic reduction in costs to below the £85/MWh target set by Government for 2026,” he said.
    Just for info, I believe the £85 figure is in 2012 monies not 2017 nor 2026 monies, and therefore compares to HPC's original strike price of £92.50, not today's inflationary linked price of about £100.

    Yes, it's confusing, or at the very least I am.

    Thought some might be interested in a Nov 2016 report on UK electricity generation costs.

    I thought page 30 table 7 was very interesting as it gives estimates for PV and wind costs in 2016, 2020 and 2030, but compares the 2013 estimates to the 2016 estimates - *spoiler alert* estimated costs dropped massively during that 3 year period.

    As Z points out, the predictions have not been very good. So it could be that costs have fallen rapidly, or also that the earlier estimates were too pessimistic, possibly deliberately given that HPC was being contracted at that point in time.

    I would also say that even the lower future estimates look a little questionable already. This month we should find out the latest off-shore wind contracts, with commissioning dates around 2021. Predictions are for £85(ish) in 2012 monies, which would be around £92 today (I think) v's the £106 in the chart for 2020.

    There have been £50/MWh off-shore contracts for Dutch farms, but these are shallow coastal waters, and exclude the electricity infrastructure costs, but still interesting.

    Also, for on-shore wind and PV the report suggests £60/MWh costs for 2030, but recent German (PV) and Italian (on-shore wind) contracts have been approx £60/MWh this year for pre-2020 commissioning, so 10yrs ahead of this report - but perhaps I'm splitting hairs on that one v's the £63-£67 for 2020 UK estimates.

    All criticisms aside, still very positive news, just a shame that the government has taken so long to get closer to the costs, and has pretty much ended most of the support for PV and on-shore wind before they were fully mature ....... so close, so close!

    ... The way that changes related to capital investment tax handling for technologies with a high investment to operating cost ratio have been stirred into the mix is extremely interesting too ... very much so when HinckleyC would be included in this subset ....

    Anyway, to the above-referenced .... what's the odds on news of UK support for domestic-scale battery storage leaking out over the summer ... something along the lines of (say) £500/kWh of usable storage capped at (say) 50% of fully installed cost, payable in quarterly instalments over (say) 7 years ?? ... it'd certainly fit in with the basic structure of (say) RHI etc and could possibly launched under the name (say) RSI (no, not that RSI, a different one !!) and would certainly leverage the potential of existing microgeneration to address peak demand within a reasonable timescale and at a reasonable cost, which at an estimated £3billion(max) even at current costs would have far more immediate grid-balancing impact than the £12billion smart-meter debacle due to there being no co-reliance on consumerisation or uptake of smart-products and/or home automation ...

    Just speculation, of course ....

    Would it only be for those with micro generation or would you be able to package it with e7 and it would again be a way for home owners with a bit of capital to make a nice profit?

    Hi

    Can't see how anyone could make a profit out of a scheme with that kind of structure considering that there'd be a cap specifically to prevent it and individuals would provide the initial capital funding - for example ....

    A (say) 13.5kWh system installed for £6350 would attract a potential £6750(500*13.5) of support, but the cap would limit this to £3175(6350/2) to be paid quarterly over 7 years ....

    ... However, someone purchasing their system from an opportunist rip-off supplier may be offered a smaller system with just 2kWh of storage for the same kind of price, in which case the support would be £1000(500*2) over 7 years, the cap wouldn't apply and therefore the integrity of the funding would be maintained ...

    Of course, such a domestic scale funding scheme would be confined by various other criteria, maybe these would link the scheme's maximum storage capacity directly to the microgeneration capacity, maybe in the case of grid-tied pv this could logically be around 4kWh of usable storage per kWp of installed pv capacity ...

    Regarding the E7/E10 overnight tariffs .... of course, utilising overnight 'cheap' tariff supply to charge the batteries in the winter would supplement lower pv generation and therefore maintain the ability to reduce peak demand - it's completely down to the capability of the unit's management system and how it's set-up ... it could even be a further condition of scheme access ...

    Hi

    True, but more than that it's a relatively inexpensive prospect. The £3billion(max) scheme mentioned earlier would result from almost all of the current pv installation base joining the scheme with 13.5kWh systems each capable of providing a peak output of 5kW. Essentially that would provide a potential to temporarily provide a maximum peak output of just under 5GW, so not insignificant considering that it's higher than HinckleyC ...

    In reality, take-up would initially still be pretty slow ... I'd be surprised if take-up was over 20% of those with installed pv systems within 5 years and average capacity was over 5kWh, which would likely result in a scheme cost of <£500million giving a reasonable daily peak power demand reduction ranging from 200MW to 500MW ...

    As mentioned earlier, all speculation, but speculation based on carefully reading between the lines of various reports such as the BEIS one referenced by Mart, taking special regard to the referenced sources as they often prove to be more interesting than the reports themselves ...

    Looking on the bright side, storage, especially if targeted towards the evening peak, would reduce the average price of leccy for everyone by peak lopping.

    The NG does (or should?) choose cheaper leccy first, so any reduction in demand at any given time removes (or prevents) supply from higher priced sources.

    Subsidies for storage might not be true subsidies at all, but rather a pre-payment by govt/leccy bodies based on future national savings.

    I am literally sitting here waiting for a suitable battery solution within price to come along and I would bite your hand off to get it. I am still quite tempted by the Growatt SP2000.

    I like the fact it is DC side, so just plug and play and you don't loose any FIT payments with it, because what doesn't get to the meter during the day , will as the battery feeds the inverter after dark.
