Smart peak-shaving that turns the grid's daily imbalance into real savings — and real income — for households.
The Peak Problem
Between 5pm and 7pm, gas stations fire up to meet demand. Electricity hits up to £3/kWh in flexibility markets — ten times what households pay.
The Overnight Opportunity
Overnight, demand drops and the grid has surplus power. Clean electricity is available for as little as 5–7p per unit — a fraction of peak prices.
How It Works
Green Streets has developed a smart scheme that help with this daily imbalance — storing cheap, clean electricity when it is abundant, then deploying it precisely when the grid is under pressure.
Clear Benefits for Everyone
Grid Relief
Reduces costs for the grid by lowering peak demand at the most critical hours.
Lower Carbon
Cuts emissions by avoiding the need to fire up gas generation during peak periods.
Household Income
Pays households for participating in balancing the system and supporting the grid.
Lower Bills
Reduces electricity costs for the household by using stored cheap overnight energy.
No Solar Required
This model works purely through intelligent storage and timing — making it accessible to far more households at a fraction of the cost.
A Smarter Entry Point
While solar can enhance the system by providing free energy, the iBillShaver scheme does not depend on solar panels. The upfront cost is significantly lower — around a quarter of a typical solar installation — because the value comes from intelligent storage and timing, not generation.
This opens the scheme to the vast majority of UK households who have not yet invested in solar, making grid-balancing participation genuinely mainstream.
The Economics at a Glance
Electricity bought overnight at ~7p/unit
Worth £1/unit at peak within the scheme
Displaces home energy typically costing ~30p/unit
The Value Stack
Buy Cheap Overnight
Charge the battery at off-peak rates of around 5–7p per kWh when the grid has surplus clean electricity and prices are at their lowest.
Export at Peak Value
Households exporting stored energy to the grid during peak hours earn high-rate payments — up to £1 per unit within the scheme's flexibility market.
Displace Home Usage
Energy used within the home from stored overnight electricity displaces grid electricity that would otherwise cost around 30p per unit on a standard tariff.
Solar can enhance the system further — but the scheme is fully viable and profitable without it. Intelligent timing is the engine.
Three Levels of Participation
The scheme is structured in three tiers, allowing households to earn and actively support grid stability and decarbonisation based on their battery capacity.

1
Entry Level
~£30 per month
2
Core Level
~£60 per month
3
Top Level
Up to £100+ per month
Estimated Annual Earnings by Level
Based on monthly earnings of £30, £60, and £100+ respectively, households can earn between £360 and over £1,200 per year simply by allowing their battery to respond intelligently to grid signals.
Turning homes into active energy assets: storing when energy is cheap and clean, and providing it when it is valuable and needed.
For the Household
Steady monthly income, lower electricity bills, and a smarter home energy system — all without solar panels.
For the Grid
Distributed, flexible storage that reduces peak demand, cuts carbon, and supports a more resilient energy system.
For the Planet
Every household that participates helps displace gas generation and accelerates the transition to clean, affordable energy.
Join the Green Streets Movement
The iBillShaver scheme is open now. Whether you start at Entry Level or go straight to Top Level, every household that joins makes the grid cleaner, smarter, and more resilient — while earning real money every month.
Start Earning Immediately
Once your battery is connected and enrolled, the system manages everything automatically — responding to grid signals around the clock, every day.
Low Risk, High Reward
With upfront costs around a quarter of a solar installation, the payback period is short and the ongoing income is consistent and predictable.
Part of Something Bigger
Every participating home becomes a node in a smarter, greener grid — collectively reducing the UK's reliance on fossil fuel peaking plants.
The grid needs help. Households can profit from providing it. Green Streets iBillShaver makes both possible — today.
