Wattstor: On-site solar, batteries and managed electricity supply

Wattstor combines financed on-site energy systems, Podium optimisation and Price Protect electricity supply for commercial and industrial customers.

Summary

Best for
Commercial and industrial sites considering financed solar and batteries alongside their supply contract.
Less suited to
A software-only meter dashboard with no change to energy procurement or site equipment.
Deployment
Designed and financed on-site systems operated with Podium EMS and an agreed supply arrangement.
Data in
Generation, storage, site demand and electricity-market information used by the energy-management service.
Pricing
Price Protect has contract-specific commodity rates, fixed non-commodity charges and an agreed cap.

Overview

Wattstor combines renewable-energy equipment, software and electricity supply for commercial and industrial customers. Its starting point is the whole site's energy arrangement rather than a single battery or reporting application. The company designs and finances on-site systems, while its Podium energy-management platform decides when to use, store or trade electricity. That makes it relevant when a business wants solar and storage but also needs a commercial structure for installation and operation. The supply contract, generation assets and optimisation service are connected parts of the proposal rather than independent products.

Offering

Price Protect combines an electricity-supply agreement with a funded on-site energy system. Wattstor explains that it becomes the customer's electricity supplier for both grid and locally generated energy, producing a single supply relationship. The tariff separates variable commodity costs from fixed non-commodity costs, with a price cap agreed at the start of the contract. This is a different purchasing model from buying an inverter outright and retaining an unrelated electricity contract. The commercial details therefore need to be compared over the full supply term, including the treatment of the installed assets.

Technology

The Podium platform coordinates how on-site generation and storage serve demand and interact with electricity markets. The Price Protect explanation connects those decisions to tariff management: renewable output, battery flexibility and trading of excess energy form part of the way the service manages cost exposure. That is an energy-management function, not just the collection of meter readings. The public pages do not provide a model-by-model protocol list or an open API specification. Equipment interfaces and external supervisory access therefore need to be defined within the design for the customer's particular site.

Markets

Wattstor's current offering targets industrial and commercial organisations facing energy costs, grid constraints and decarbonisation requirements. Its homepage case material includes a South Oxfordshire biogas site combining solar, storage and Price Protect, illustrating a business with existing energy infrastructure rather than a standard domestic battery installation. The service is relevant where generation, load and storage can be coordinated commercially. It is less comparable to a fixed hardware package because the operating profile and supply agreement help determine the project. The contact directory provides offices in London, Munich and Brno.

Company

Wattstor's company history dates its founding to 2013 and describes Podium as the original energy-management platform. It identifies Ara Partners as the majority growth-equity investor from 2023, connecting that investment to expansion of operations, research and funded on-site systems. The privacy notice identifies Wattstor Ltd as the England and Wales company, number 08344409. The contact page separately lists the London office and Wattstor s.r.o. in Brno, alongside Munich. These distinguish the legal entities and operating offices within the group. Its official company information identifies London, United Kingdom as headquarters.
