據(jù)油價網(wǎng)12月23日消息稱，一位知名能源專家警告稱，英國將竭力進口價格高昂的天然氣，以滿足今年冬季的能源需求，以避免無風時的停電。

盛寶銀行（Saxo Bank）大宗商品策略主管Ole Hansen告訴City A.M. ，國內(nèi)可再生能源斷斷續(xù)續(xù)的表現(xiàn)讓西方國家付出了高昂的代價。

他認為，除了非常昂貴的天然氣之外，該國缺乏可靠的替代基本電力負荷。

他說:“歐洲和英國的基本負荷供應不足，這可以在無風的日子里降低價格的飆升。尤其是在英國，可再生能源發(fā)電一直非常不穩(wěn)定，從高產(chǎn)到低產(chǎn)的變化相當于打開和關(guān)閉15座核電站，每座核電站的發(fā)電量為1吉瓦。

“展望未來，它凸顯了在沒有風的情況下，電力供應成本非常高昂的風險，因為核能投入低于正常水平，供應必須由天然氣來彌補。”

風力發(fā)電一直在英國能源結(jié)構(gòu)中占重要的少數(shù)，目前占英國電力的45%。

然而，最近幾周，當國家電網(wǎng)在本月早些時候要求英國的三個備用煤電機組預熱時，這一要求下降到8%以下，然后在需求緩解時終止了這一要求。

相反，英國一直依賴美國和卡塔爾等海外供應商的大量液化天然氣流入，以滿足本國和歐洲大陸的能源需求。

Saxo Bank: UK Will Scramble For Gas When Wind Isn’t Blowing

The UK will be scrambling for highly expensive gas imports to meet its energy needs this winter to stave off blackouts whenever the wind doesn’t blow, warned a leading energy expert.

Ole Hansen, head of commodity strategy at Saxo Bank, told City A.M. that the intermittent performance of domestic renewable power is proving costly for the West.

He argued the country lacks a reliable alternative base load of power aside from highly expensive natural gas.

He said: “Europe and the UK are in short supply of base-load which can reduce the spikes seen in prices on days the wind does not blow. Not least in the UK, where the power generation from renewables has been so volatile that the change from high production to low has been the equivalent of turning on and off 15 nuclear power plants, each producing 1GW.

“Going forward, it highlights the risk of very expensive power days when the wind doesn’t blow and where supply has to be made up from gas as nuclear input is lower than normal.”

Wind power has consistently made up a significant minority of the UK’s energy mix, and is currently generating 45 percent of the UK’s power.

However, in recent weeks, this dropped to below eight percent, when National Grid called for the UK’s three standby coal power units to warm up earlier this month, before terminating the request when demand eased.

The UK has instead relied on vast inflows of liquefied natural gas from overseas vendors such as the US and Qatar to meet both its energy needs and demand on the continent.
