Pohjoismaat joutuvat tuomaan sähköä jo 2025?

The Nordic region’s shrinking power surplus means it could switch from being a net exporter to a net importer between 2025-2027 in certain weather conditions, said Swedish TSO Svenska Kraftnat (SvK).

The TSO’s report, published late on Tuesday, showed the region’s annual power surplus would drop from 38 TWh in 2023 to 13 TWh in 2027.

In the case of a very wet and mild year, the Nordic region could produce 20-30 TWh more power than in a very dry and cold year and these variables mean the region could become a net importer, said the TSO.

SvK expected the power demand in Finland, Denmark, Sweden and Norway to rise from 410 TWh in 2023 to 517 TWh in 2027, mostly due to more electrolysis needed for the green transition. Meanwhile, new power production capacity was likely to grow at a much slower rate, it said. [EMP]

St1: Otaniemen geolämpölaitos epäonnistui

Fortum irrottautuu hankkeesta. Fortum ei pidä 6,4 kilometrin syvyistä lämpökaivoa taloudellisesti kannattavana, koska lämpökaivosta ei saatukaan pumpattua ylös riittävän lämmintä vettä. Alun perin tarkoituksena oli syöttää vesi suoraan kaukolämpöverkkoon, mutta kokeissa osoittautui, että ylös tulee vain kädenlämpöistä vettä. Ja Investointi tekniikkaan on moninkertainen suhteessa vaihtoehtoisiin tapoihin, kuten teollisuuden hukkalämpöön.

USA: PUURAKENTEINEN 122 HUONEEN HOTELLI PALOI

The fire that consumed the 122-room hotel project occurred the evening of April 12, when no construction workers were on site. A fast-developing blaze consumed a hotel under construction in Camarillo, Calif. The fire, which was reported shortly after 7 p.m., is believed to have started on the third floor of an uncompleted four-story hotel.

AFRIKAN SUURIN VESIVOIMALAITOS AVATTU ETIOPIASSA

Ethiopia has begun generating electricity at its new 5,000 MW roller-compacted concrete gravity-type dam on the Nile River. The first 375 MW went to the national grid on Feb. 20. Prime Minister Abiy Ahmed switched on the first of the 13 installed turbines at the $4.8-billion hydropower plant—also known as Grand Ethiopian Renaissance Dam, ታላቁ የኢትዮጵያ ሕዳሴ ግድብ in Amharic—as he sought to allay fears the facility could impact the Nile’s flow to downriver countries Sudan and Egypt.

This is the largest hydroelectric power plant in Africa. The 145-m-high, 1,780-m-long dam with 74 billion m3 reservoir could take up to seven years to fill. [ENR]
