Wind power can’t fill Sweden’s nuclear energy gap

Another example of the obvious inadequacy of part-time unpredictable wind power, and its consequencies for countries that insist on pursuing it. Relying on imports to avoid power shortages can’t be ideal for any country.

Sweden will have to import more electricity during winter as the country, a net power exporter to the rest of Europe, shifts from nuclear to wind, its grid operator said.

Last winter, the first since the closure of its Oskarshamn 1 reactor, stretched Sweden’s resources as peak consumption rose by 800 megawatt (MW), triggering start-up procedures in its reserve energy plants.

Sweden’s power balance will deteriorate further from next winter, the country will need imports and the situation will become worse with two more of its reactors closing by 2020, state-grid Svenska Kraftnat (SVK) said in a report on Monday.

“For next winter (if it’s a normal winter) we expect Sweden to (need to) import 400 MW more than it exports during the hour with the highest consumption,” SVK’s electricity system analyst Erik Hellstrom, and the author of the report, told Reuters.

Hellstrom said that if the coming winter is a “10-year winter” (colder than a normal winter), Sweden’s imports will rise by as much as 1,500 MW more than it exports in the hour with the highest consumption.

Of Sweden’s eight remaining nuclear reactors, two will close soon, Ringhals 2 in 2019 and Ringhals 1 the year after, cutting a combined production of 1,700 MW from its power system, 40 percent of which is nuclear output-dependent.

    Reblogged this on Climatism and commented:
    WESTERN climate-theory-obsessed governments continue to ramp up unreliables – wind and solar – that continue to fail dismally wherever they are installed. Energy poverty, sky rocketing power bills, grid instability and the destruction of pristine landscapes, flora and fauna among the many costs of low energy-density, weather dependent novelty ‘energy’ sources!

    EITHER, green propaganda is beyond successful or lucrative kickbacks for politicians who give the ‘green’ light are too good to refuse. A combination of both seems likely.

    ECO-insanity on stilts.

    The Russians will no doubt happily offer Sweden power when those wirlythings don’t turn, but the Swedes should make sure to read the fine print. Between the Greens and Putin, I know who I would prefer. Neither.

    Windfarms operate like a zero hours contractors who are paid well continuously but only works when they feel like it.

    Insanity is everywhere. In the U.S. northeast, climate zealots have blocked pipelines which would deliver low cost, readily available natural gas from nearby states. During the recent winter, shortages forced those states to buy high priced LNG delivered by tanker from Russia.

    The latest renewables moneypit…

    HVDC grids to facilitate cross-border energy exchange

    In the future, point-to-point offshore connections are expected to evolve into multi-terminal HVDC systems to increase power exchange between countries and strengthen the energy market of renewables
    . . .
    For example, experts are discussing building the so-called North Sea offshore grid, an interconnected network to replace the site-by-site link between the renewable sources and the mainland of 10 countries.

    “There is a perspective of creating an offshore DC-terminal in the North Sea to facilitate not only the integration of offshore resources but also the power exchange between countries,” D’Arco says. “Energy can be transferred from a country with an excess of production to a country lacking energy or, in general, from a country where the energy cost is lower to a country where this cost is higher.”

    – – –
    But in this (in)glorious future, if a country lacking energy is next door to all the others, the reason they lack it is likely to be lack of wind strength? In which case the others are going to be in much the same boat, as will be the proposed North Sea ‘power exchange’?

    The use of HVDC for point to point power transmission over long distances is a good solution for efficient energy transfers from grid to grid. They require a high degree of management on both ends for safe and effective operation. Best used for transfers between Base Power Generators. This is NOT a Throw the switch operation like in AC systems. The energy in a DC wire has mass/momentum. In HVDC, High mass/momentum that must be managed at both ends of the wire. This is not a good thing for power transfers from a erratic power supply…pg

  7. p.g.sharrow says:

    The largest fallacy in this entire Green agenda is the Idea that they ALL can dump excess power into the grid when they have it and take power out when they have a shortage. Somebody else will supply the base line storage and supply. Like all Socialists and Liberals, Somebody else will save them from their poor planning and bad judgement, Just like all the rest of this AGW Religion, their dogma is base on simple minded beliefs and wishes, not on real physical fact…pg
