Drax Energy — Supplier Profile

(formerly Haven Power)

About Drax Energy

Drax Energy is the business electricity supply arm of Drax Group plc — the UK’s largest renewable electricity generator by output. Drax Group is headquartered in Selby, North Yorkshire, adjacent to the famous Drax Power Station, which the company has progressively converted from coal to sustainable biomass over the past decade.

The Haven Power story: In 2006, Haven Power launched in Ipswich as an independent commercial energy specialist. Drax Group acquired Haven Power in 2009, marking the Group’s first move into direct business energy supply. Haven Power traded successfully for over a decade under that brand, becoming well-known in the broker market for its renewable energy credentials and Ipswich-based customer service team. Haven Power no longer operates as a separate supplier. All former Haven Power customers are now managed through Drax Energy. The brand consolidation is complete; customers contacting Haven Power are redirected to Drax Energy channels.

Drax Energy supplies renewable electricity to approximately 9,000 businesses and organisations across the UK. The supplier is positioned firmly in the large commercial and industrial (I&C) segment — since April 2022, Drax has not quoted for businesses using fewer than 30,000 kWh annually. This is not a supplier for micro-businesses or small SMEs; it is a specialist renewable electricity supplier for medium to large commercial, industrial, and corporate customers.

Generation credentials: This is where Drax is genuinely distinctive. Unlike most suppliers that purchase renewable energy from third parties (or buy REGOs on the open market), Drax generates its own renewable electricity from:

• Drax Power Station, Selby, North Yorkshire — converted biomass generation
• Cruachan pumped hydro storage station — one of only four pumped hydro facilities in the UK, located in the Scottish Highlands
• Lanark and Galloway run-of-river hydro schemes, Scotland
• Biomass production facilities in North America

The result is that Drax’s fuel mix contains 93.1% renewable electricity — more than double the UK supplier average — with CO₂ emissions of just 34g/kWh compared to the UK average of approximately 154g/kWh.

Drax Group aims to be carbon negative by 2030 — removing more CO₂ from the atmosphere than it emits. This is supported by investment in Bioenergy Carbon Capture and Storage (BECCS) technology at the Selby site.

What to Expect as a Business Customer

Security — Fixed Pricing

Drax Energy offers both fixed and flexible tariff structures, all delivered through a bespoke tendering process — there are no published standard rates. Pricing is created around your specific consumption profile and prevailing market rates on the day of tender.

Fixed tariffs (for businesses using over 30MWh annually):

• Fixed Complete: Fixes most third-party costs alongside the commodity rate — high certainty, closest to an all-in fixed price
• Fixed Clarity: Fixes the commodity unit rate; most third-party costs pass through at actual rates — more market transparency
• Fixed Threshold: Fixes third-party costs up to a set threshold; costs beyond the threshold pass through

Fixed tariffs are available for 1–3 years with a 90-day notice period required for renewal or switching.

Flexible tariffs (for higher-consumption users, typically over 2GWh annually):

• Flex Complete: Fixes most third-party costs; gives high-consumption users control over energy purchasing in response to market conditions
• Flex Clarity: Passes through most third-party costs; provides the clearest view of trading activities for sophisticated buyers

No termination notice needed to switch after fixed period: Per Drax’s own variable rates page, businesses do not need to send a termination notice to switch supplier — though any outstanding balance must be settled before transfer. Outstanding debt may result in Drax objecting to the switch.

Variable rates: Businesses that do not renew at contract end move to Drax’s variable (out-of-contract) rates, which are published on the Drax website and updated for January 2026. These are significantly higher than fixed contract rates.

Demand Side Response (DSR): Available for eligible businesses — financial incentive for reducing electricity consumption at peak times. Drax manages the DSR system on behalf of participating customers.

Transparency — Account Management

• My Drax Energy portal: Online account management available from any device; submit meter readings, view account balances by site, monitor energy usage
• Dedicated account manager: Each business customer is assigned a UK-based account manager — a key differentiator from automated or shared service models
• Energy Optimisation programme: A tiered structure from energy efficiency audit through to recommendation and implementation — Drax goes beyond the meter to help businesses reduce consumption
• Corporate PPAs: Direct Power Purchase Agreements linking specific businesses to Drax’s renewable generation assets; strengthens Scope 2 reporting credentials

Convenience — Payments and Account Management

• Online portal (My Drax Energy): Full account management, usage monitoring, balance tracking
• Dedicated account manager: Named contact for each business account
• Smart meters and half-hourly meters: Provided and maintained by Drax; enables real-time usage data
• VAT: 20% standard (business rates); Climate Change Levy (CCL) applicable unless business holds a CCL exemption certificate
• Change of tenancy: Requires proactive notification to Drax with correct transfer dates and forwarding address — failure to notify promptly results in continued billing

Services

• Corporate PPAs: Drax’s strongest value-add for large businesses — direct contractual links to UK renewable generation
• Energy management tools and consultancy
• Carbon offset options
• BECCS (Bioenergy Carbon Capture and Storage): Drax is developing this technology at scale at the Selby site — businesses contracting with Drax may eventually be able to attribute carbon removal credits
• Multi-site management: Drax has experience managing energy supply across multiple business locations
• New connections: Drax provides new electricity connections for eligible sites

Environmental

• Fuel mix (April 2024–March 2025): 93.1% renewable electricity — predominantly biomass (~70%), hydroelectric (~15%), pumped storage (~8%)
• CO₂ intensity: 34g/kWh — among the lowest of any major UK supplier; less than a quarter of the UK average of ~154g/kWh
• REGO-backed: Renewable Energy Guarantees of Origin certificates provided for Scope 2 reporting
• Sustainability controversy: Drax’s biomass credentials have been challenged by environmental groups. Drax burns compressed wood pellets sourced from working forests, primarily in North America and the Baltic states. Critics argue that burning whole trees (including primary forest material) releases carbon that takes decades to re-absorb, and that international carbon accounting rules that exclude the CO₂ at point of combustion are misleading. Drax receives substantial government subsidies for this generation. This is a live and contested environmental debate — businesses with stringent sustainability policies should review Drax’s sourcing evidence before committing to a biomass-backed green tariff claim.

Sector Fit Assessment

Sector	Fit	Notes
Hospitality	★★☆☆☆	Below 30,000 kWh threshold for many hospitality sites; not Drax’s target market
Manufacturing	★★★★★	High-consumption manufacturing with carbon reduction commitments is the ideal Drax customer profile
Retail (large)	★★★★☆	Multi-site large retailers with meaningful electricity consumption can benefit from portfolio management and CPPAs
Education (large)	★★★★☆	Universities and academy chains with high consumption and net zero targets suit Drax’s offering
Healthcare (large)	★★★★☆	NHS trusts and large private healthcare operators fit the consumption profile
Logistics	★★★★★	Energy-intensive warehousing and cold chain operations — high consumption, renewable credentials increasingly important
Corporate/office campuses	★★★★★	Large offices with Scope 2 reporting requirements and net zero commitments
SMEs (general)	★☆☆☆☆	Below minimum threshold — Drax is not the right supplier for typical SMEs

Telnergy’s Take

What we like:

• 93.1% renewable electricity from own generation assets — this is genuinely differentiated from suppliers that merely purchase REGOs. Drax’s renewable credentials come from real generation infrastructure
• Dedicated account manager for every business — not a call centre queue; a named contact who understands your account
• Carbon negative ambition by 2030 — one of the most ambitious decarbonisation targets in the UK energy sector
• Bespoke tendering process — pricing is built around your specific consumption profile rather than a generic tariff; for high-consumption businesses, this typically delivers better value
• Corporate PPAs available — for businesses wanting contractual links to specific renewable generation rather than pooled certificates
• 90-day notice period — longer than some suppliers, but known in advance and standard for I&C contracts

Watch points:

• Trustpilot score of 1.5/5 from 34 reviews requires significant context. The small review count (only 34) is typical of a business-only supplier that doesn’t serve domestic customers and doesn’t actively encourage public reviews. The negative reviews predominantly relate to out-of-contract billing disputes, change of tenancy situations, and the 2021–22 energy crisis period when rates rose sharply. These are real experiences but not necessarily representative of contracted customer relationships
• 30,000 kWh minimum consumption — a hard threshold. Many SMEs, micro-businesses, and smaller commercial properties simply don’t meet it. If you’re below this threshold, Drax will not quote for you
• Electricity only by default — Drax’s core proposition is electricity; gas is available but is not a strength of the offering. Businesses needing gas supply may need a separate gas supplier
• Biomass sustainability controversy — serious environmental organisations raise substantive concerns about Drax’s wood pellet sourcing and the carbon accounting framework. Businesses with robust ESG commitments should review this evidence before presenting Drax as their green energy credential

Is Drax Right For You?

Consider Drax Energy if:

• Your business uses over 30,000 kWh of electricity annually
• You have Scope 2 emissions reporting obligations and want the strongest possible renewable generation credentials — not just REGO certificates
• You want a dedicated account manager and bespoke pricing rather than an off-the-shelf tariff
• Your business has corporate net zero commitments and you want a supplier whose carbon ambition matches your own
• You want a Corporate PPA directly linking your business to specific UK renewable generation

Consider alternatives if:

• Your consumption is below 30,000 kWh (Drax will not quote for you — consider Valda, SmartestEnergy, or Octopus Energy for Business)
• You need a gas supply as your primary energy requirement (SEFE Energy, TotalEnergies, or Crown Gas & Power are better positioned)
• Your sustainability team has concerns about biomass sustainability claims (Good Energy’s direct PPA model or Ecotricity’s wind-and-solar focus may be more defensible)
• You need a supplier with a high volume of positive public reviews for stakeholder assurance purposes
