Create visibility
Show load profiles, self-consumption, export and peaks.
Energy optimisation
Optimise the whole energy flow, not isolated devices.
PHT combines metering, tariffs, PV forecasts, battery status, heat demand and flexible loads in a transparent operating strategy.

Quick answer
Energy optimisation means choosing the right time and end use for each kilowatt-hour. The energy price, network charges, levies, peaks, efficiency, comfort and equipment wear all matter.
Energy optimisation
Use dynamic prices correctly
Assess all tariff components
Use the full bill and any demand-based charges.
Use forecasts
Include solar production, temperature, heat demand and vehicle availability.
Respond automatically
Control storage, heat pump, hot water and flexible loads within safe limits.
Process
From the first photograph to a working installation.
Data baseline
Clarify metering points, resolution, quality and tariff.
Objective
Define cost, self-consumption, autonomy, peaks or carbon priority.
Rules and automation
Implement logic with minimum run times and safety limits.
Continuous improvement
Review the result monthly and seasonally.
Energy optimisation
Use dynamic prices correctly
All-in price, not spot alone
Wholesale energy is only one component; network and tariff rules remain.
Avoid simultaneous peaks
The battery, EV and heat pump should not all increase import together.
Quantify flexibility
Only genuinely shiftable energy can be optimised.

Local SEO should not consist of copied town pages. A real project depends on the grid connection, current tariffs, shading, building services, permissions and measured demand. PHT combines these local facts with an integrated system design.

Frequently asked questions
Frequently asked questions
Does a dynamic tariff always save money?
No. It is most useful where controllable loads exist and all-in price differences are large enough.
Can a battery charge from the grid?
Often technically yes; suitability depends on the system, contract and full cost.
How are peaks limited?
A central controller sets a total import limit and allocates available power by priority.
What data is required?
Time-series consumption and generation, tariff data, device states and clear operating limits.
