Energy Market Services

What Energy Market Services does

Energy Market Services (EMS) is a New Zealand-based energy market infrastructure provider, established in 1994 as a commercial business group within Transpower NZ Ltd, a State Owned Enterprise tasked with owning and operating New Zealand's National Grid. The company serves electricity retailers, renewable energy generators, energy traders, distribution networks, and industrial sites across New Zealand through a portfolio of mandated and commercial services spanning the em6 electricity data hub, the emsTradepoint commodity trading exchange, Financial Transmission Rights (FTR) auctions, International Renewable Energy Certificate (I-REC(E)) issuance, retail metering, gas allocation, and Grid Exit Point metering. EMS holds statutory roles appointed by the Electricity Authority as FTR Manager, contracted by the Gas Industry Company as Allocation Agent under the Gas (Downstream Reconciliation) Rules 2008, and is accredited by the I-TRACK Foundation as the sole I-REC(E) issuer for electricity produced in New Zealand.

The core technological asset is the em6 platform, which delivers real-time and historical New Zealand electricity market data through dashboards, widgets, and a comprehensive API suite. The platform covers regional and node-level pricing, generation by fuel type (hydro, wind, solar, geothermal, gas, coal), load and demand data, HVDC flows, carbon intensity metrics, reserves, residuals, and intermittent generation forecasts up to 36 hours out. The Dynamic Carbon Tracker module provides half-hourly carbon intensity calculations using generator-specific emissions factors, with methodology verified by Toitū Envirocare. emsTradepoint operates as a central counterparty exchange for natural gas and carbon credit spot and forward trading, while the FTR auction system at app.ftr.co.nz manages locational price risk across New Zealand's nodal electricity market. The platform integrates with the Evident Registry for I-REC(E) operations and Amazon Cognito for FTR user authentication.

EMS generates revenue through a mix of subscription fees, transaction-based fees, and contracted managed services. The em6 platform uses a tiered subscription model with Free, Basic, Pro Select, and Dynamic Carbon Tracker tiers, priced based on data feeds and user seats. I-REC(E) revenue combines one-time device registration (NZD 1,500), renewal fees (NZD 600 after 5 years), and per-MWh issuance fees (NZD 0.04–0.05), with Participant fees (trade account opening EUR 500, annual EUR 2,000, redemption EUR 0.06/MWh) invoiced by Evident Services B.V. The Gas Allocation Agent role is a contracted managed service under Gas Industry Company governance. Headquartered in Wellington with 11–50 employees, EMS distributes through self-serve digital channels (em6 app, emsTradepoint portal, FTR portal, Evident registry) supplemented by direct sales for enterprise subscriptions and onboarding support.

Broad incumbents

• Argus Media: Global energy and commodity price reporting agency with extensive market data, news, and analytics across power, gas, and carbon markets. Comparable to EMS's em6 and emsTradepoint in serving energy market participants with pricing intelligence, though at much larger scale and broader scope.
• EPEX SPOT: One of Europe's largest power exchanges, operating spot and day-ahead markets with extensive market data services and APIs. Comparable to EMS's emsTradepoint and market data offerings in the same energy trading infrastructure category, though at significantly larger scale and broader geographic scope.
• S&P Global Commodity Insights (formerly Platts): Global provider of energy commodity benchmarks, market data, and analytics — including power, gas, and carbon markets. Comparable to em6 as an energy market data subscription product and to emsTradepoint's carbon credit market, though at significantly larger global scale.
• European Energy Exchange (EEX): European energy exchange operator providing power, gas, and environmental market infrastructure with associated market data services. Comparable to EMS's exchange (emsTradepoint) and market data (em6) offerings, with overlap in environmental products and wholesale electricity market infrastructure.
• ICE (Intercontinental Exchange): Major global exchange operator with extensive power, natural gas, and environmental products markets and extensive market data services. Overlaps with EMS's emsTradepoint and em6 in trading infrastructure, market data, and environmental commodity services, though serving a much larger and more diverse customer base.

Direct peers

• Australian Energy Market Operator (AEMO): AEMO operates Australia's National Electricity Market and provides extensive market data, dashboards, and APIs (similar to em6). Comparable as a regulated national energy market operator delivering market data infrastructure, FTR-like settlement, and real-time market intelligence to retailers, generators, and traders.

Similar financial transmission rights / congestion product structure.
• Xpansiv (formerly APX): Xpansiv acquired Evident — EMS's I-REC(E) registry partner — in May 2026, making Xpansiv the underlying registry platform for EMS's I-REC issuance. Comparable as an environmental commodities infrastructure provider, with overlap in renewable energy certificate registries and carbon credit markets served through emsTradepoint.
• Energy Market Company (EMC) Singapore: EMC operates Singapore's National Electricity Market as a market operator and settlement system provider. Closely comparable to EMS's role as a commercial market services provider within a national grid operator (Transpower), with similar functions in market data, settlement, and participant services.

Emerging players
