Treehouse Energy ⚡️🔋 Electricity markets, EPEX, imbalance | DC fast charging EV’s, eTrux Energy 🚚 | V2G |
Born at 363 ppm CO₂
🇳🇱☀️ In NL daalt de PV profiel factor met ~2,1% per GWp extra capaciteit.
Sinds 2018 van 100% naar <50% in 2025.

📉 Lineair: 0% bij 52 GWp
📉 Exponentieel: 22% bij 55 GWp

➡️ Meer zon = minder waarde per kWh. Tijd voor opslag & flexibiliteit! ⚡🔋

Ik analyseerde de PV weighted price van Juni vs Juli 2025 in NL:
- flink slechter weer
- veel meer bewolking hebben we gehad
- veel meer regenachtige dagen (zoals ook vandaag weer)

Zie hier de Day-Ahead resultaten, bron: NED.nl

er was flink minder PV productie, 15% minder GWh opgewekt in Juli

Best veel zonne-energie. Des te opmerkelijker dat nihil en negatieve stroomprijzen vrijwel afwezig waren in juli. Dit blijkt ook uit de grafiek waarin ik het aandeel zon & wind uitzet tegen de gem. stroomprijs per dag. Immer sterke correlatie; deze maand niet.

En voor Airco gebruik

Op basis van NED.nl CO2 emissie op uurbasis

En met @knmi.nl temp data van De Bilt

En EPEX prijs data van Entsoe

Wat is de gewogen gemiddelde uitstoot van het verbruik van een warmtepomp op jaarbasis? 2024

Antwoord:
241 gCO_2 / kWh elektrisch

Daar produceert de warmtepomp gemiddeld 4.6 kWh_thermisch voor

Dus per kWh_th is dit 52 gCO_2/kWh_th

en is daarmee meer dan 4x schoner
dan warmte uit een CV ketel

Ik heb zelf de PV profiel gewogen waarde op Day-Ahead markt uitgerekend

dit voor de PV orientatie mix zoals die in NL aanwezig is, door data van NED.nl

gecombineerd met Day-Ahead prijs data van Entsoe

In een Plotly dashboard ziet dat er zo uit:

PV waarde per maand, sinds 1 jan 2022, t/m 20 juli 2025

1) PV productie in MWh/MWp per maand
2) PV waarde in €/MWp/mnd
3) gemiddelde waarde Day-Ahead versus PV gewogen DA waarde

How this software helps me code 👩‍💻

Using VS Code with Github Copilot and Gemini 2.0 Flash

my Github repository: github.com/MaykThewesse...

see my screen recording:

🚗 Gasoline car: 100 input → 30 useful (30% efficiency)
🚛 Diesel car: 100 input → 40 useful (40% efficiency)
⚡ Electric vehicle: ~47 input → 40 useful (85% efficiency)

🔋 EVs use less than half the energy compared to fossil cars for the same motion

Best is to transform trucking industry to electric

they only account for ~3% of vehicles on the road

but consume 28% of fuel for transport (!)

due to high number of operating hours per truck

-> Electric-truck with a 600kWh battery saves a lot of fuel and saves on costs!

🔥 Conventional heating (boilers):
- needs> 100 units of input energy to deliver 91% of useful heat

⚡ Heat pumps (COP 3.5):
-> needs only 17.1 units of input energy to deliver the same 60 units of heat.

~5.8x less input energy for the same comfort

Massive efficiency gain switching to heat pumps

if Electric vehicles replaced all gasoline vehicles ⛽️

Wind and solar could already displace global gasoline demand ☀️💨

How do Dutch electricity prices evolve?

Here the hourly prices from 2024

- Hourly average price
Big dip during day-time
High prices during breakfast and evening

- Histogram shows distrubtion and occurance

Gas sluipverbruik
- door CV-ketel
- of lekkage?

Kijken of we dit kunnen voorkomen

Gas verlies is 0.3 m3 per dag
- 3.0 kWh verloren gas per dag
- €0.42/d gas kosten = €150/jaar

Is dit de comfort-functie van de ketel die stand-by tapwater warm houdt?

Er is geen boilervat..

Europe should protect its own sovereignty for the long-term
Europe should set clear demands on a post war Russia. No heavy arms, no air force, no navies, militia style units only. No high tech production. All western harbors under control of peace keepers. Full financial compensation to Ukraine. Dechekististation. etc.

This is the right demand to Russia

with less demanding they will not give in - they do negotiation way different than ours

Russia doesn’t agree and settle for a win-win compromise

They will only reduce their demands, if we force them to by big demands
Europe should set clear demands on a post war Russia. No heavy arms, no air force, no navies, militia style units only. No high tech production. All western harbors under control of peace keepers. Full financial compensation to Ukraine. Dechekististation. etc.

Hey @dannyoosterveer.bsky.social

Bij Tibber
opslag kosten levering elektriciteit = €0,02178/kWh + EPEX

maar weet jij:
- hoeveel kosten worden er gerekend bij teruglevering PV energie?

is dat €0,000/kWh zoals bij Zonneplan?

of toch een afslag?
