The average turnkey price of a typical 7 kWp household #rooftop#solar system in #Finland has dropped to 7.700 €, as demand slowed down and there are no more shortages in component supply or skilled installation personnel.
Households can also apply for a 40% tax rebate on the installation work, which probably brings the total cost to below 1 €/Wp.
Demand for batteries and DSM automation exceeds expectations. There is no feed-in tariff so consumers try to avoid feed-in. https://yle.fi/a/74-20079845
@osma@burger_jaap The compensation for micro feed-in electricity is specified by the seller, and companies can compete on this. Spot price minus 0,2 or 0,3 cent/kWh seems typical. In addition, the local distribution company is allowed to charge 0,07 cent/kWh.
Are there studies showing that solar feed in prices are lower than average spot? Daytime prices are higher than night, which benefits solar power. But winter is also costlier than summer...
Solar share is still too low to affect market
@osma@burger_jaap Your claim was that the most likely times of excess solar energy are those with lowest spot prices. I was expecting more empirical data to support that claim.
@BM_Visser Quite a fascinating list. What explains Hungary's leadership on this list, almost 20% of electricity from solar?
Neighbors like Czechia are Romania are nowhere near that level, and last one is the solar thermal pioneer Austria, with even lower PV share than Finland?
Is it policy, culture or perhaps a exceptionally enabling environment for PV installers?
This new 11 MW(th) Air-Water #HeatPump in Vermo, Espoo is the largest of it's kind in #Finland and a first step to 100MW Air-Source HPs on the #Fortum#DistrictHeating network in Espoo, Kauniainen and Kirkkonummi.
It was built last year next to a 160 MW oil-fired peak boiler. This week temperatures plunge below the design temperature -15°C of the #ASHP, so the peak boiler takes over. Luckily only for few days annually, and using bio-oil. #SectorCoupling#Wärmewende
BTW, does somebody know of a bigger #ASHP anywhere? The only multi-MW heat pumps I found are using wastewater or seawater as heat source. A few ground source exist in Finland but I believe at only about 4MW.
@nemobis I have also wondered why Fortum is unwilling to build large ground source heat pumps for #districtHeating. Perhaps they are still experimenting, and air-source HPs are both cheaper to procure and easier to relocate if necessary. #Lippulaiva shopping mall already has 4MW GSHP, so perhaps they consider it to be more potent competition to their district heat and generally oppose such development.
Also, Fortum is not building seasonal heat storage like Helen and Vantaan Energia #VECTES.
@nemobis On the other hand, Fortum does have some bad experience with the failed 6km #DeepHeat borehole in Otaniemi. And they do recover heat from wastewater in Blominmäki and Suomenoja treatment plants, so that source seems exhausted.
@jon Local newspapers often get significant revenue from automobile industry advertising, and it would be naive to believe that this didn't have an effect on the journalistic content of these papers. Automobile marketing promotes freedom, to which parking restrictions are in direct conflict.
Is there a central government ombudsman available that can be contacted when local Ordnungsamt fails to enforce parking laws?
@jon The Ordnungsamt would no doubt respond to the Ombudsman that they don't have resources for more enforcement. But depending on where the fines are paid, more enforcement would probably pay for itself. So the Ordnungsamt could also be accused of wasting public money by failing to collect due payments. Also, they are distorting the market and violating the commercial rights of private parking facility operators by competing with publicly funded and illegal roadside parking.
There are some good items in the programme:
-utilities must provide customers with demand response automation
-citizen's participation in small scale generation increases, including through Energy Communities
-end double taxation when charging/discharging electricity storage
-support long and short term heat storage
-support pumped hydro
-R&D increase to 4% of GDP with focus on energy transition
-independence of Russian imports
-fossil fuels phased out in heat and power generation by 2030
But there are some silly entries, particularly on wind and nuclear energy. There is an unsubstantiated claim that Finland needs more nuclear energy. Despite repeated calls for competitiveness and technology neutrality, nukes will benefit from public financing and capacity markets.
Wind power will be penalised by distance minimums and the requirement to include dispatchable capacity. This is precisely the nonsense that the industry feared.
