Flexitricity is a UK energy flexibility, demand-response and asset-optimisation company. Instead of simply selling gas or electricity at a unit rate, it helps businesses, generators and battery owners earn revenue from flexible energy assets.
Its customers can make batteries, standby generators, combined heat and power systems, industrial equipment, refrigeration, heating systems and electric vehicle chargers available to support the electricity system. Flexitricity then trades or dispatches that flexibility through markets operated by the National Energy System Operator, electricity networks and wholesale trading platforms.
Flexitricity’s services are therefore most relevant to organisations with controllable electricity demand, generation or storage. A small business looking only for a fixed electricity tariff is unlikely to be its target customer.
The company operates a virtual power plant exceeding 1GW and says its platform can optimise individual assets ranging from 7kW to more than 50MW. Drax completed its acquisition of Flexitricity on 1 April 2026, having valued the business at £36 million before closing adjustments.
Our review finds that Flexitricity offers one of the UK’s most comprehensive routes into flexibility markets. Its strengths include broad market access, 24-hour asset control and substantial battery-optimisation experience. Its principal limitation is commercial transparency: prices, revenue-sharing arrangements and projected returns are calculated individually and are not published as standard tariffs.

Flexitricity Limited is an active Scottish company whose principal registered activity is the trade of electricity. It was originally incorporated as Martin Energy Limited before changing its name to Flexitricity in 2008.
Is Flexitricity an energy supplier?
Flexitricity holds a different position in the market from suppliers such as British Gas, EDF, E.ON or Octopus Energy.
Ofgem granted Flexitricity a non-domestic electricity supply licence in March 2018. This allowed the company to combine electricity supply with access to markets such as the Balancing Mechanism. Flexitricity subsequently launched a commercial gas and electricity supply service later that year.
However, its current public proposition is predominantly focused on:
- Flexible-asset optimisation
- Demand-side response
- Battery storage
- Energy trading
- Grid-balancing services
- Market access
- Control systems
- Revenue generation from energy assets
Flexitricity does not currently publish a range of conventional fixed, variable or renewable business tariffs with pence-per-kWh prices and daily standing charges.
A business seeking a straightforward supply contract should therefore compare conventional commercial energy suppliers. Flexitricity becomes relevant when the organisation has an asset or process that can be turned up, turned down, charged, discharged or rescheduled.
EnergyCosts.co.uk rating
| Review category | Rating |
|---|---|
| Flexibility market access | 4.9 out of 5 |
| Battery optimisation | 4.8 out of 5 |
| Demand-response experience | 4.8 out of 5 |
| Technology and control | 4.7 out of 5 |
| Revenue transparency | 3.4 out of 5 |
| Suitability for small businesses | 3.0 out of 5 |
| Suitability for large energy users | 4.8 out of 5 |
| Overall rating | 4.4 out of 5 |
Flexitricity scores highly because it provides access to an unusually broad selection of electricity markets through one operating platform.
Its lower score for revenue transparency reflects the absence of public fees, revenue shares or guaranteed returns. This is understandable because every asset has different technical and operational characteristics, but it makes it difficult for a business to assess value without completing a detailed evaluation.
How Flexitricity works
Flexitricity connects energy assets at different sites into a virtual power plant. This aggregated portfolio can then operate in electricity markets in a similar way to a conventional generating station.
For example, Flexitricity might:
- Discharge a battery when electricity prices are high
- Charge a battery during lower-priced periods
- Temporarily reduce refrigeration demand
- Increase or reduce industrial production
- Start a standby generator
- Alter the output from a combined heat and power unit
- Reschedule an electric vehicle charging fleet
- Change the operation of a heat pump
- Provide additional generation during a grid shortfall
- Increase demand when excess electricity is available
Flexitricity uses automated controls, predictive modelling, trading systems and a continuously staffed control room. Its demand-response service covers initial asset surveys, integration, market scheduling, dispatch, reporting, billing and account management.
The core business operation remains the customer’s priority. Availability windows and operating limits are agreed so that the asset should not be dispatched when it is required for its primary purpose.
Flexitricity services
Flexitricity’s current service range can be divided into four broad categories.
| Service category | What Flexitricity provides |
|---|---|
| Asset optimisation | Automated and human-led management of generation, storage and flexible consumption |
| Demand-side response | Revenue from changing electricity demand or generation |
| Market access | Entry into wholesale, balancing, reserve, capacity and network markets |
| Infrastructure and control | Hardware, communications, metering, testing and automated dispatch |
FlexGO
FlexGO is Flexitricity’s newer flexibility service for industrial, commercial and aggregated domestic assets.
It is designed to reduce the cost and complexity of connecting smaller or distributed assets to electricity markets. Assets can be integrated through an application programming interface, a connected device or an on-site control outstation.
Flexitricity identifies suitable assets, handles their connection and manages subsequent market participation. It says FlexGO could allow businesses to earn tens of thousands of pounds per megawatt each year, although actual returns depend on the asset, location, availability and prevailing market prices.
Suitable technologies can include:
- Refrigeration systems
- Heat pumps
- Electric vehicle charging points
- Batteries
- Industrial equipment
- Backup generators
- Aggregated domestic devices
- Controllable heating or cooling
- Electrolysers
FlexGO is particularly significant for businesses with behind-the-meter assets that may previously have been too small or complex to participate individually.
Demand-side response
Demand-side response allows a business to earn revenue by changing how much electricity it consumes or generates when requested.
Flexitricity can optimise industrial processes, refrigeration, HVAC equipment, heat pumps, charge points and standby generation. It manages assets in real time while observing operating restrictions specified by the customer.
Demand response can involve either direction:
| Flexibility action | Example |
|---|---|
| Reduce demand | Temporarily turn down refrigeration compressors |
| Increase demand | Charge a battery when excess electricity is available |
| Increase generation | Start a CHP unit or standby generator |
| Reduce generation | Lower export when the network is constrained |
| Shift demand | Move an industrial process to a different period |
| Export stored electricity | Discharge a battery during a high-value period |
Payments can come from making capacity available, responding to a dispatch instruction, trading electricity or avoiding high-cost periods.
Battery energy storage optimisation
Battery energy storage is now one of Flexitricity’s most important services.
Its battery platform moves assets between different markets and revenue opportunities rather than relying on one fixed service. The available revenue stack can include:
- Wholesale electricity markets
- The Balancing Mechanism
- Frequency response
- Reserve services
- NIV chasing
- Distribution network services
- Restoration services
- The Capacity Market
Flexitricity’s models account for battery characteristics such as cycle limits, depth of discharge, temperature and degradation costs. Trading recommendations are produced using machine-learning models, executed by its trading desk and monitored continuously by its control room.
The service also covers:
- Interface design
- Asset onboarding
- Market prequalification
- Dispatch integration
- Performance reporting
- Settlement
- Billing
- Supply requirements
This end-to-end approach is valuable because maximum gross trading revenue is not necessarily the same as maximum investor return. Excessive cycling can accelerate degradation, reduce available capacity and shorten the useful life of a battery.
Flexitricity revenue streams
A connected asset can potentially earn money through several overlapping routes.
| Revenue stream | How value is created |
|---|---|
| Wholesale arbitrage | Buying or consuming at low prices and selling or reducing use at high prices |
| Balancing Mechanism | Changing generation or demand at the request of NESO |
| Frequency response | Responding rapidly to changes in system frequency |
| Reserve services | Holding capacity available for system shortfalls |
| Capacity Market | Receiving payments for dependable capacity |
| Local network flexibility | Responding to constraints on a distribution network |
| Cost avoidance | Reducing demand during expensive charging periods |
| NIV chasing | Managing exposure to system imbalance prices |
| Renewable co-optimisation | Combining generation and storage to improve market value |
| Demand Flexibility Service | Reducing demand during specified periods where eligible |
The best combination depends on response speed, minimum operating level, asset duration, efficiency, grid connection, location and permitted operating hours.
Balancing Mechanism
The Balancing Mechanism is one of the principal tools used by NESO to balance electricity supply and demand close to real time.
Participants submit offers and bids indicating the price at which they can increase or decrease electricity generation or consumption. Flexible assets can earn revenue when NESO accepts one of these actions.
Flexitricity provides:
- Asset preparation
- Market registration
- Bid and offer submission
- Automated dispatch
- Real-time monitoring
- Performance reporting
- Financial settlement
- Trading optimisation
A battery might be instructed to discharge when the electricity system is short of power. An industrial site could instead reduce consumption, producing a similar balancing effect.
Flexitricity became the first company to complete a Balancing Mechanism transaction as a Virtual Lead Party using behind-the-meter batteries in 2020.
Frequency response
The GB electricity system operates at a nominal frequency of 50Hz. Frequency falls when demand exceeds generation and rises when generation exceeds demand.
Frequency-response assets automatically alter their output or consumption to counter these movements. Batteries are particularly suitable because they can respond rapidly and operate in both directions.
Flexitricity provides access to frequency-response markets and monitors asset performance to ensure contracted response requirements are met.
Factors affecting eligibility include:
- Response speed
- Metering accuracy
- Minimum capacity
- Communication reliability
- Duration
- State-of-charge management
- Ability to respond automatically
- Availability during contracted periods
Frequency response can provide recurring income, but prices are determined competitively and can fall as more batteries enter the market.
Reserve services
Reserve services provide additional capacity when demand is higher than expected or generation is lost.
An asset may provide positive reserve by increasing generation or reducing consumption. Negative reserve can be delivered by reducing generation or increasing electricity use.
Flexitricity’s control room receives instructions, automatically dispatches assets and monitors the delivered response. It also optimises the prices submitted for reserve participation.
Potential reserve assets include:
- Battery storage
- Fast-start generators
- CHP engines
- Industrial loads
- Refrigeration
- Electric vehicle charging
- Heat pumps
- Electrolysers
Capacity Market
The Capacity Market pays generators, storage operators and eligible demand-response providers for being available during periods of system stress.
Payments are primarily linked to available capacity rather than ordinary electricity generation. Participants must meet testing and delivery requirements, and failure to perform can result in penalties or lost revenue.
Flexitricity handles processes including:
- Asset assessment
- Prequalification
- Auction participation
- Metering requirements
- Testing
- Performance reporting
- Capacity Market settlement
- Stress-event response
Flexitricity was the first aggregator to obtain a Capacity Market contract in 2014. Its company history also records the first hydrogen electrolyser to receive a 15-year demand-side response Capacity Market agreement in 2025.
DNO flexibility services
Distribution Network Operators purchase local flexibility to manage constraints on regional electricity networks.
Instead of immediately reinforcing cables, transformers or substations, a DNO may pay local assets to reduce demand, increase generation or alter exports during constrained periods.
Flexitricity can identify eligible locations, enter assets into procurement exercises and manage dispatch. Requirements differ considerably by distribution region and can be highly location-specific.
A business in one postcode may therefore have access to a valuable local service that is unavailable to an otherwise identical site elsewhere.
Cost avoidance
Some flexibility value comes from avoiding costs rather than receiving a direct market payment.
Flexitricity can help businesses reduce consumption during expensive periods. This may lower exposure to time-sensitive network charges, peak import prices or capacity-related costs.
Potential savings depend on the customer’s:
- Supply contract
- Metering arrangement
- Network charging band
- Maximum demand
- Consumption profile
- Ability to reschedule operations
- Local distribution network
- Electricity price structure
Cost avoidance can sometimes be combined with market revenue, although participation in one service may restrict availability for another.
Flexitricity prices and fees
Flexitricity does not publish standard fees.
There is no public tariff table showing:
- A fixed monthly platform charge
- Connection costs
- Revenue-share percentages
- Trading fees
- Management fees
- Capacity Market commission
- Minimum annual payments
- Settlement charges
Each proposal is likely to depend on the asset and commercial structure.
Possible contract structures in the flexibility market include:
| Commercial structure | How it normally works |
|---|---|
| Revenue share | The customer and optimiser divide market income |
| Fixed management fee | The customer pays a regular service charge |
| Fee per megawatt | Charges are linked to connected capacity |
| Floor arrangement | The optimiser provides a minimum income level |
| Tolling structure | The optimiser obtains defined dispatch or trading rights |
| Gain share | The optimiser receives part of the value above an agreed baseline |
| Hybrid model | Fixed fees and performance-linked payments are combined |
These structures are examples of how asset optimisation may be contracted across the industry. Businesses must confirm Flexitricity’s actual proposal in their individual commercial offer.
How much could a business earn?
Flexitricity says FlexGO could earn participating businesses tens of thousands of pounds per megawatt per year. It does not provide one universal revenue forecast because the result depends on market prices and technical availability.
The following table illustrates what different annual revenue levels would mean. These are hypothetical calculations rather than Flexitricity quotations.
| Flexible capacity | £10,000 per MW a year | £25,000 per MW a year | £40,000 per MW a year |
|---|---|---|---|
| 250kW | £2,500 | £6,250 | £10,000 |
| 500kW | £5,000 | £12,500 | £20,000 |
| 1MW | £10,000 | £25,000 | £40,000 |
| 2MW | £20,000 | £50,000 | £80,000 |
| 5MW | £50,000 | £125,000 | £200,000 |
| 10MW | £100,000 | £250,000 | £400,000 |
The amount retained by the business could be lower after Flexitricity’s fees, revenue share, operating costs, fuel, battery degradation and taxation.
Flexitricity revenue examples
Flexitricity has published several customer case studies containing historical revenue and savings figures.
| Customer | Flexible asset | Capacity | Published revenue or saving | Approximate value per MW |
|---|---|---|---|---|
| Rotherham Metropolitan Borough Council | Standby generator | 800kW | More than £30,000 a year | More than £37,500 per MW |
| University of Edinburgh | CHP assets | 5.73MW | £71,000 annual average | About £12,390 per MW |
| Aberdeen Heat & Power | CHP and district heating | 3.4MW | £28,560–£76,500 a year | £8,400–£22,500 per MW |
Rotherham Council’s case study reported more than £30,000 of annual revenue from 800kW of standby generation participating in STOR, the Capacity Market and historic triad management.
The University of Edinburgh reported average annual revenue and savings of £71,000 from 5.73MW of CHP capacity, including historic triad rebates.
Aberdeen Heat & Power’s published Capacity Market estimate ranged from £28,560 to £76,500 annually for 3.4MW, depending on auction prices.
These figures should not be treated as current quotations. The case studies describe arrangements established under earlier market conditions, and some associated charging arrangements have since changed. They demonstrate the scale of potential value rather than the revenue a new customer would necessarily receive in 2026.
Which assets can Flexitricity optimise?
Flexitricity says it can manage assets ranging from approximately 7kW to more than 50MW.
| Asset | Possible flexibility |
|---|---|
| Battery storage | Charge, discharge or reserve capacity |
| Standby generator | Generate during a system requirement |
| CHP engine | Change generation around heat and electricity needs |
| Refrigeration | Temporarily reduce compressor demand |
| Cold storage | Use stored thermal capacity to shift consumption |
| HVAC system | Alter heating, ventilation or cooling demand |
| Heat pump | Move heating demand between periods |
| EV chargers | Delay, accelerate or reduce charging |
| Industrial process | Reschedule or temporarily reduce a load |
| Electrolyser | Adjust hydrogen-production demand |
| Solar-plus-storage | Optimise export and battery operation |
| Renewable generator | Manage output, imbalance and co-located storage |
| District heating | Alter CHP, boiler or storage operation |
| Data centre | Use backup or controllable infrastructure within strict limits |
The minimum technically connectable asset is not necessarily the minimum commercially viable project. Smaller devices may need to be aggregated with many similar assets to justify communications, metering and market-registration costs.
Industries suited to Flexitricity
Flexitricity is potentially suitable for:
- Food production
- Cold storage
- Supermarkets
- Warehousing
- Manufacturing
- Data centres
- Hospitals
- Universities
- Local authorities
- Water companies
- District heating operators
- Commercial property portfolios
- Logistics fleets
- Battery developers
- Renewable generators
- Electric vehicle charging platforms
- Infrastructure funds
- Energy-intensive industrial sites
Businesses with continuous, inflexible consumption and no storage or generation may have little capacity to monetise.
Battery investors and developers
Flexitricity is particularly relevant to owners and developers of grid-scale battery projects.
A battery optimiser must decide how to allocate the asset across competing opportunities. Committing capacity to one frequency-response service may prevent the battery from using that capacity in the wholesale market or Balancing Mechanism.
Important optimisation considerations include:
- Day-ahead electricity prices
- Intraday prices
- Balancing Mechanism spreads
- Reserve auction results
- Frequency-response prices
- State of charge
- Round-trip efficiency
- Connection constraints
- Battery warranty conditions
- Maximum annual cycles
- Depth-of-discharge limits
- Degradation value
- Capacity Market obligations
- Planned maintenance
- Availability guarantees
Flexitricity combines machine-led forecasting with human trading and control-room oversight. This can be preferable to a purely automated optimiser where unusual market or operational events require manual intervention.
The Drax acquisition
Drax announced an agreement to buy Flexitricity in January 2026 and completed the transaction on 1 April 2026.
The transaction valued Flexitricity at £36 million before customary adjustments. At completion, Drax said Flexitricity provided optimisation and route-to-market services to more than 900MW of operational assets, principally batteries, gas peaking plants, renewable generation and demand-side response.
Drax expects the Flexitricity platform to support a gigawatt-scale battery pipeline and provide:
- Third-party asset optimisation
- Route-to-market services
- Floor arrangements
- Tolling structures
- Battery trading
- Demand-side response
- Balancing and ancillary services
The acquisition could strengthen Flexitricity’s access to Drax’s trading, supply and generation capabilities. This is an inference based on the complementary activities described by Drax rather than a guarantee that every existing customer will receive different terms or higher revenue.
Potential customers should establish whether the acquisition affects:
- Contract counterparties
- Credit support
- Trading arrangements
- Data sharing
- Existing revenue shares
- Access to Drax supply products
- Independence of optimisation decisions
- Conflicts between Drax-owned and third-party assets
Flexitricity technology
Flexitricity operates a proprietary controls and optimisation platform supported by predictive modelling and automated dispatch.
For batteries, its models evaluate technical variables such as:
- Cycle count
- Depth of discharge
- Temperature
- Efficiency
- Degradation cost
- Energy prices
- Expected system conditions
- Contracted service requirements
Recommended schedules are reviewed and executed through a human-in-the-loop trading process. Automated systems then dispatch the asset under continuous control-room supervision.
For industrial and commercial demand response, on-site systems can communicate operating availability and receive dispatch instructions.
The precise installation may involve:
- A control outstation
- Secure communications
- Asset telemetry
- Revenue-grade metering
- An API integration
- Connection to a building management system
- Connection to a battery management system
- Generator controls
- Safety interlocks
- Local override functions
How onboarding works
The exact process depends on the asset, but a Flexitricity project will typically involve the following stages.
| Stage | Likely activity |
|---|---|
| Initial assessment | Review assets, meters, electricity use and operating restrictions |
| Data analysis | Examine historical load, generation and availability |
| Revenue modelling | Identify accessible markets and estimate income |
| Commercial proposal | Agree fees, revenue sharing and contract duration |
| Technical design | Specify metering, controls and communications |
| Installation | Connect the asset to the operating platform |
| Prequalification | Complete tests and market-registration requirements |
| Operational testing | Demonstrate response speed and reliability |
| Go-live | Begin trading, dispatch or availability provision |
| Settlement | Calculate delivered flexibility and customer payments |
| Ongoing optimisation | Move the asset between markets as opportunities change |
Flexitricity says it manages surveys, integration, schedule execution, reporting, billing and account management for demand-response customers.

Customer service and complaints
Flexitricity provides standard commercial contact facilities and a separate 24-hour technical support service for operational customers. Its operational support team can be contacted at any time when connected assets or control systems require attention.
Its published complaints process states that complaints should be acknowledged within two working days. Customers should normally receive a proposed resolution within five working days.
Flexitricity is also a member of Flex Assure, a voluntary industry code intended to establish standards for business-facing flexibility providers. Flexitricity was the first accredited member to complete the scheme’s periodic audit process.
We did not find a substantial dedicated Trustpilot profile for Flexitricity at the time of this review. Its public case studies contain positive customer feedback, but these have been selected and published by Flexitricity itself and should not be treated as equivalent to a large independent review sample.
Flexitricity advantages and disadvantages
Advantages
Extensive market access: Flexitricity can place assets into wholesale, balancing, frequency, reserve, capacity and local network markets.
Long operating history: The company has operated in British demand response since 2004 and records several industry firsts.
Broad asset range: It works with batteries, generators, industrial demand, refrigeration, heat pumps, EV charging and other technologies.
24-hour control: Connected assets are monitored and dispatched from a continuously staffed control room.
Battery expertise: Flexitricity considers trading income alongside efficiency, cycling and degradation.
End-to-end management: Surveys, integration, prequalification, operation, reporting and settlement can be managed through one provider.
FlexGO access: The newer platform may make smaller and more distributed assets commercially viable.
Flex Assure membership: Independent scheme membership provides additional confidence around operating standards.
Drax ownership: The acquisition gives Flexitricity the backing of a much larger energy group.
Disadvantages
No public pricing: Businesses cannot see fees or revenue-sharing percentages before requesting a proposal.
No guaranteed universal return: Earnings vary with market prices, asset availability, competition and regulation.
Complex contracts: Market access, baseline, penalty and exclusivity provisions require careful review.
Limited relevance to ordinary small businesses: Companies without flexible assets are unlikely to benefit.
Potential equipment costs: Metering, communications and control installations may be required.
Operational risk: Dispatch must be coordinated carefully to avoid interfering with core business requirements.
Battery degradation: Higher trading revenue can be offset by additional cycling and reduced asset life.
Markets can become saturated: Increased competition can reduce frequency-response and other service prices.
Limited independent reviews: There is little public customer-review data compared with conventional business suppliers.
Is Flexitricity a good choice?
Flexitricity is a strong option for businesses and investors that own meaningful flexible energy assets.
Its most compelling proposition is not an electricity tariff but a route into markets that are normally difficult for individual businesses to access. The combination of automation, human trading, 24-hour control and numerous revenue streams is particularly valuable for batteries and large industrial sites.
Flexitricity may be suitable where a business has:
- At least one controllable energy asset
- A predictable operating profile
- Reliable metering and communications
- Capacity that can be made available without disrupting operations
- A battery, generator, CHP unit or flexible load
- Sufficient scale to cover connection and management costs
- A willingness to enter a multi-year commercial arrangement
It is less suitable for a small office, shop or hospitality company that simply wants cheaper gas and electricity. Such a business should compare conventional supply tariffs unless it also operates a meaningful battery, EV charging portfolio, refrigeration system or other controllable load.
Drax’s 2026 acquisition gives Flexitricity greater financial and commercial backing. It could also broaden the structures available to battery owners, including route-to-market, floor and tolling agreements.
Overall, Flexitricity earns a rating of 4.4 out of 5. It is one of the strongest UK flexibility providers on technology, market coverage and operating experience, but businesses must obtain a bespoke proposal and scrutinise the revenue assumptions, fees, operational limits and risk allocation.
FAQ
Flexitricity has held non-domestic energy supply licences, but its current main proposition is flexibility and asset optimisation. It does not publish conventional fixed or variable business tariff prices.
Flexitricity connects flexible energy assets to wholesale, balancing, frequency, reserve, capacity and local network markets. It controls and trades the assets to generate revenue or reduce energy costs.
Flexitricity says FlexGO could produce tens of thousands of pounds per megawatt annually. Actual earnings depend on the asset, location, availability, operating limits, market prices, fees and revenue share.
Suitable assets include batteries, CHP engines, standby generators, refrigeration, HVAC systems, heat pumps, EV chargers, industrial equipment, renewable generation and hydrogen electrolysers.
Only some small businesses will qualify. A company normally needs controllable electricity demand, generation or storage. An ordinary small premises without flexible assets is unlikely to benefit.
Yes. Battery optimisation is a core service. Flexitricity trades batteries through wholesale and balancing markets while considering state of charge, efficiency, cycling, temperature and degradation.
Flexitricity does not currently publish standard fixed business tariffs. Businesses seeking a fixed unit rate and standing charge should compare conventional commercial suppliers.
Drax Group completed its acquisition of Flexitricity on 1 April 2026. The transaction valued Flexitricity at £36 million before customary closing adjustments.
FlexGO is a flexibility service for industrial, commercial and aggregated domestic assets. It connects assets through APIs, devices or control outstations and manages their participation in electricity markets.
Demand-side response involves changing electricity consumption or generation in return for financial value. A business might reduce refrigeration demand, start a generator or reschedule EV charging.
Yes, subject to the agreed arrangement. Flexitricity can remotely dispatch connected equipment, while customer-defined availability and operating restrictions are intended to protect core operations.
Flexitricity operates a 24-hour control room and provides round-the-clock operational support for connected assets and systems.
Not ordinarily. Revenue depends on market conditions and asset performance unless the individual agreement includes a floor, guarantee or other structured payment mechanism.
Yes. Flexitricity is a Flex Assure member and was the first accredited provider to complete the scheme’s periodic audit process.
Yes. It is particularly relevant to battery owners needing market access, automated dispatch, trading, revenue stacking, settlement and ongoing optimisation.
