The regulatory cycle, modelled end to end.

PolicyBox® is a simulation and data platform for regulated electricity markets. Allowed returns, price controls and market dynamics, built the way each regulator builds them, across 28+ European markets plus Singapore.

Platform

One model per market, not one model for all markets.

Regulated returns are set by formula, and every regulator's formula is different. PolicyBox implements each covered market's own methodology: its risk-free rate convention, its approach to beta and gearing, its indexation, its control period structure.

Simulation, not just data. The platform goes beyond reporting published determinations. It reconstructs the mechanics behind them, so you can stress assumptions, run counterfactuals and see how allowed returns respond as market inputs move.

The platform draws on live data feeds: government bond yields, market data, regulatory publications and meteorological inputs, refreshed continuously and stored with full history.

Capabilities

From determination to distribution.

Each module reflects how regulators and markets actually work, then extends it with the analysis published documents cannot give you.

Cost of capital

Methodology-faithful WACC for every covered market. Risk-free rates, betas, gearing and allowances assembled under each regulator's own framework.

Price control simulation

Revenue building blocks and control mechanics simulated across periods, with scenario and sensitivity analysis on the inputs that matter.

RAB roll-forward

Regulatory asset base evolution: additions, depreciation and indexation projected forward under alternative assumptions.

Monte Carlo analysis

Stochastic simulation of returns and revenues under uncertainty. Full distributions and confidence bands rather than point estimates.

Balancing and weather

Balancing price analytics with integrated meteorological data, linking system conditions to market outcomes.

Market intelligence

Per-market briefs covering the regulatory framework, current determinations and the outlook for the next reset.

IN DEVELOPMENT · Cross-market reset forecasting. Authenticated API access for quantitative workflows is available to portal clients.

Coverage

Built for cross-market work.

The same questions, answered consistently across jurisdictions, on each jurisdiction's own terms.

Who it serves

For every side of the regulatory process.

Networks and utilities

Benchmark your allowed returns against peers and prepare for the next control period with the regulator's own mechanics.

Investors and infrastructure funds

Assess regulated cash flows and return frameworks consistently across markets before capital is committed.

Regulators and policymakers

Compare methodologies internationally and test how alternative choices flow through to bills and returns.

Advisers and expert witnesses

Ground submissions and testimony in reproducible, methodology-faithful analysis.

Access

See it on your markets.
