Assuming US LNG as marginal supplier in the winter and min summer price since 2010 over summer, the spread would be 3.1 EUR/MWh.
->
Если предположить, что американские поставщики СПГ обеспечивают маржинальное предложение в зимний период, а также допустить, что [этим?] летом цены на СПГ/газ будут минимальными с 2010 года, разброс цен на СПГ/газ [по всему миру] будет составлять 3,1 евро на мегаватт-час.

Надеюсь, смысл я уловил правильно. Может, кто-нибудь подкорректирует терминологию?

BP: U.S. will be world marginal supplier of LNG

BP reached similar conclusions in its Energy Outlook 2017. BP predicts that LNG supply in the US will grow by 19 BCFPD in the next 20 years, making the US the world’s largest LNG exporter. While LNG currently makes up about 32% of all globally traded gas, this share will grow to half by 2035. This shipping infrastructure will allow gas markets to increasingly become integrated. Instead of the current significant spread in global gas prices, prices will be much more uniform.

According to BP, the U.S.’s geographical position will also contribute to its potential role as the marginal supplier for the world. While Australian LNG is expected to be almost entirely to Asia, U.S. LNG will likely go to Europe, Asia and South & Central America.

Marginal suppliers

In consequential LCA modelling, long-term market trends and constraints play key roles for the identification of the long-term marginal suppliers of each product, that is, the suppliers that will change their production capacity in response to an accumulated change in demand for the product.

Важная поправка!

<...> разброс цен на СПГ/газ [по всему миру] будет составлять 3,1 евро на мегаватт-час.
->
<...> разница между максимальной и минимальной ценами на [СПГ, газ, электроэнергию — не знаю] в течение года составит 3,1 евро на мегаватт-час.

Если что, все претензии прошу предъявлять Роснефти. :)

Похоже, цена (3,1 евро на мегаватт-час) относится к СПГ/газу:

== BEGIN QUOTE ==

Компания рассматривает возможность дополнительных партий объемов 125 тыс. куб. м каждая против обычных в 75 тыс. куб. м. Тем не менее, цена на СПГ выросла с начала года с 31 евро за МВт/ч до 38 евро за МВт/ч.

Правда, они там пишут «МВт/ч» вместо «МВт·ч», ну да какие проблемы. (рука-лицо)

Can the U.S. Crack the $90 Billion LNG Market? - Bloomberg
https://www.bloomberg.com/news/articles/2017-11-02/can-the-u...

== BEGIN QUOTE ==

The $90 billion global market for liquefied natural gas will be reshaped in 2018 as a number of large, long-term contracts start to expire. Growing supplies from the U.S., higher demand in Europe and Asia, and geopolitical tension surrounding Russia and Qatar, the world’s two biggest gas suppliers, promise to shift long-established trading patterns.

For decades the majority of LNG bought and sold around the world has been governed by long-term contracts of up to 20 years. A fifth of those will expire from 2018 to 2020. Over the next decade, contracts governing 80 percent of all global LNG trade will be rewritten. For now, the LNG market is in the midst of an enormous supply glut, in part because of the advent of U.S. exports in the past two years. That glut is likely to persist until at least 2020, keeping prices low.

<...>

Europe’s need for more LNG could offer an opening for U.S. exporters. Yet in the current low-price environment, they can’t win new business just by undercutting competitors. “U.S. LNG continues to be promoted as an attractive diversification away from Russian gas but currently lacks the economic justification to secure a sizable market,” says Claudio Steuer, director of SyEnergy Ltd., a U.K.-based energy consultant. And the world’s top LNG exporter, the tiny Gulf nation of Qatar, is looking to expand market share in Europe. It recently announced plans to boost LNG production by 30 percent over the next several years. Nigeria and other LNG exporters also face a battle over expiring LNG contracts, and Algeria says it’s preparing a strategy on how to export its gas amid oversupply.

<...>

U.S. LNG companies hope to sign big deals in 2018. That would please the Trump administration. Selling more LNG to Asia could shave billions of dollars off the U.S. trade deficit with Japan, South Korea, and China. “LNG contract roll-off is a huge opportunity,” says Kathleen Eisbrenner, CEO of NextDecade Corp., which is seeking to build an export terminal in Texas and install an offshore import facility in Ireland. Next year “is going to be a pivotal year.”
