Anyone still weathering it out with Agile?

Toodles · 2025-08-14T15:24:43Z

Being curious, I have continued to monitor the daily rates with OE’s. Agile; I rarely see any substantial number of HH’s. below 15 pence per KWh. Much of the time Agile exceeds 15 pence for the cheapest HH’s day to day. I am wondering if any readers have stuck it out and weathered this storm and if the future for Agile is on an upward trend for prices. The cynic in me makes me think that Agile has become a loss maker that is now intolerable to OE. Comments would be welcomed please (I’m still on Cosy which seems to be a winner over Agile at present and for perhaps the last year) Regards, Toodles.

@jamespetts I agree it's extremely hard to calculate ROI on batteries as it will also see changes in usage patterns as well as opening up tariff options.

Factors include

EV? Usage? Charger?
Solar panels? Size?
Inverter charge/discharge rates?
Batteries? Size?
ASHP? size? Usage?
Automation options including HA, WonderWatt Homely etc?

In my case

EV? Yes Usage? Around 2000kWh/pa. Charger - zappi
Solar panels yes Size 8.5kw
Inverter charge/discharge rates? Only 2.6kWh
Batteries? Size 24.6kWh
ASHP yes size? 16kw Usage: 6000kWh/pa. Weather compensation controls
Automation options including HA, WonderWatt Homely etc? Yes. WonderWatt

I crank up heating of house and hot water at night on cheap rates
Solar probably produces around 6500kWh/pa (not optimal orientation etc). Endeavour to export majority

Usage: say 6k ashp, 2k ev, 2k all other usage Inc lighting, cooking.

Import: say 3k kWh/pa at cheap rate overnight for later force export as well as filling batteries for own usage + charge ev + run ashp

Expected TOTAL imports 13000kWh @ 8p Intelligent Go = £1040

Expected TOTAL exports 6500kWh @ 15p = £975

Expected Net cost £65 for 1 year usage in 2025

So I conclude the batteries are a no brainer for me. But I could not have assumed that in advance. Charge/discharge rate is a significant barrier to maximising but newer installations are likely to be better especially if part of a setup such as Tesla, GivEnergy All-in-one etc

@tim441 As you say Tim, very difficult to quantify any savings or ROI even, for a battery; I have often wondered about the savings I make from my solar PV - the figures might be very different with or without a battery. Without a battery, I might quantify my solar ‘gain’ at 25 pence per kW/h as I would not likely be using a TOU tariff but a fixed one. As I do have a battery (Tesla 27kW/h Powerwall), I opted for Cosy and pay ~ 13 pence per kW/h and let the battery take the strain. But wait! I am only showing a solar ‘gain’ of ~13 pence per kW/h now!?😉. In fact, my exported energy realises 15 pence per kW/h with Octopus Outgoing Fixed (at the moment anyway!) Oh, now my brain hurts!
