Rheora ETRM · Energy & Utilities · Trading & Risk Management Operate

Demand-to-hedge for UK power & gas — on one MHHS-ready system.

Rheora ETRM turns half-hourly forecast error into a managed P&L line — before MHHS makes it a daily cash-out bill. Forecast half-hourly demand and price, hedge the shape, trade it, settle it, and prove the imbalance cost you avoided, on one governed platform built for the UK power-and-gas supply market.

The problem

Under MHHS, every settlement period shows you exactly how wrong your forecast was.

From October 2026, Market-wide Half-Hourly Settlement (MHHS) settles every meter on its actual reading. Forecast error stops being socialised across load-profile classes and becomes each supplier's own daily, sometimes violent, cash-out line.

01
Forecast error becomes a cash-out billA quiet £30/MWh half-hour can cash out near £3,000/MWh when wind drops — and most desks have no system that sees it coming, period by period, before it lands.
02
Demand, hedging, trading & settlement live in separate toolsThe plan can't see the live position. Desks re-key between forecasting spreadsheets, a broker blotter and a settlement reconciliation — so exposure is always stale.
03
Generic ETRMs don't speak UK48-period shape, EFA blocks, GSP groups, ECVN notifications, MHHS migration and REMIT obligations get bolted onto a commodity-agnostic core, slowly and brittly.
04
Forecasts without provenance or confidencePoint forecasts with no saved forecast-vs-actual history, no per-period or per-segment error decomposition and no honest confidence bands are exactly what the regulator — and the desk — can't trust.
How Rheora works

One closed loop, from half-hourly demand to settled P&L.

The same disciplined Amplinth loop, tuned to UK energy trading and risk — every forecast is persisted and reconciled, so the next call is sharper.

01

Connect

Metered volumes, Elexon system & imbalance prices (BMRS), gas, market prices (streaming), weather & REMIT/news; broker import & tenant connectors.

02

Reason

Six production ML models blended by a learned stacking ensemble, retrained nightly by a walk-forward harness; a 3-agent market-intelligence pipeline. No black box.

03

Recommend

Hedge ratio, open exposure & shape risk per settlement period; price-trigger alerts; imbalance-cost forecasts; VaR/sensitivity; risk-limit-bounded suggestions.

04

Act

Trade capture, OMS & paper trading execute or dry-run hedges; settlement, ECVN & exception queues drive the middle office — human-in-the-loop, permissioned.

05

Prove

Every forecast reconciled against actuals; P&L and imbalance attributed per period — imbalance cost avoided in EVA terms.

Capabilities

~45 capability modules across the full trade lifecycle.

Forecast → hedge → trade → confirm → settle → report — UK market structure (48 half-hourly periods, EFA blocks, GSP groups, Elexon cash-out, MHHS migration, REMIT) is a first-class concept, not a configuration afterthought.

Demand-to-hedge & positions

Per-segment half-hourly demand forecasting (domestic, SME, EV-heavy, heat-pump, legacy NHH) with P10/P50/P90 bands; live hedge positions, unhedged exposure, hedge ratio and shape/baseload mismatch per settlement period — the demand forecast and live position share one book.

Half-hourly settlement (MHHS)

Daily metered-volume and Elexon system-price ingestion; MHHS migration tracking by MPAN measurement class (A–G) and GSP group; ECVN notification flows; load profiling and seeding for new tenants and segments.

ML price forecasting & backtesting

An XGBoost day-ahead price model, an LSTM base forecaster and quantile-regression confidence bands, fused by a learned ElasticNetCV stacking ensemble. A walk-forward backtest harness retrains nightly across ~4 years and is judged on the worst slice — season, day-of-week, period, segment — not the headline MAPE.

Imbalance & P&L

Daily P&L attribution and expected imbalance cash-out cost or benefit per period, from forecast-vs-actual and Elexon imbalance prices; system buy/sell (SBP/SSP) imbalance forecasting; configurable price-trigger and exposure rules that raise hedge-timing and volume alerts.

Risk analytics

Value at Risk on open positions; price and fundamental sensitivities (gas, carbon, generation mix, cross-border) feeding both the risk view and the sensitivity-baseline forecaster; collateral and counterparty exposure; a master-agreement (GTMA/EFET-style) registry tied to counterparties and trades.

REMIT compliance & surveillance

Hourly REMIT inside-information and market-abuse analysis; trade surveillance over abusive or anomalous patterns; a compliance-obligations workflow; periodic access reviews (SoD/recertification); and a centralised operational exception queue with triage.

Trading, OMS & gas

Forward, day-ahead and intraday power trade capture and blotter; order management with venue-routing concepts; a full paper-trading simulation to dry-run strategy without market impact; and a separate gas demand-and-price stack with its own models, positions and analytics.

Market data, intelligence & AI Copilot

Live and historic market data with a streaming channel, forward-curve construction and weather feature engineering; a 3-agent market-intelligence pipeline that turns outages, news and weather into quantified price-impact scenarios; and an AI Trading Copilot for natural-language Q&A grounded in your trading and market data.

Outcomes

Deployed and running in the cloud — MHHS-ready by design.

The breadth is genuinely in production: ~45 capability modules wired, ~25 UI pages and six ML models retrained nightly, multi-tenant. Every number below carries a maturity label and a source.

Maturity matters here. Capability breadth and forecast-vs-actual provenance are realized — every forecast is persisted at generation and reconciled against actuals back-filled from BMRS, gas and metered tables. Forecast-accuracy and imbalance-saving figures are modelled (walk-forward backtest over ~4 years) or target outcomes in EVA terms, to be validated against each customer's baseline. Energy-company names are market context, not customers; any reference logos are illustrative.

How it works

Connect → Customize → Operate.

Connect Rheora to your meter, Elexon/BMRS, gas, market-data, weather and broker feeds. Customize the segments, hedge rules, risk limits and REMIT obligations to your portfolio — the shape is reusable; the market logic is what we tailor. Operate the closed loop in production, where every forecast is reconciled and every hedge is human-gated.

Why Amplinth

Not a generic ETRM — a UK-native demand-to-hedge loop.

Industry-deep

UK-native and MHHS-ready by design — 48-period shape, EFA blocks, GSP groups, ECVN, MHHS migration, Elexon cash-out and REMIT are first-class, not bolted onto a commodity-agnostic core.

Governed & explainable

Honest, retraining-backtested forecasting: six split models, a learned stacking ensemble, quantile confidence bands, every forecast persisted and reconciled. The AI copilot and intelligence pipeline stay advisory — human-in-the-loop on every hedge.

Proven & accountable

One system for demand, hedging, trading, settlement and imbalance/P&L — so exposure-per-period is live, not re-keyed. Value framed in EVA: imbalance cost avoided vs the un-hedged baseline.
