Speedwell expertise, modern analytical tools
Powerup combines Speedwell's 20+ years of weather-index expertise with modern high-resolution generation modeling and portfolio analytics.
The Speedwell name carries significant weight in the renewable energy risk community: its wind and solar power generation indices are established instruments used in hedging and risk transfer globally.
Analytics for every stage of the PPA lifecycle
Powerup serves developers, corporate buyers, operators, utilities, investors, and fund managers at different points in the renewable energy value chain.
PPA pricing and negotiation
PPA pricing and negotiation
A developer or corporate buyer models wind and solar generation at farm and portfolio levels to quantify volume, shape, and cannibalization risks before signing a PPA.
Powerup enables scenario testing across different contract structures, weather assumptions, and market conditions, helping both sides of a negotiation understand what they are agreeing to.
Better preparation leads to stronger positions and more sustainable long-term outcomes.

Revenue stabilization
Revenue stabilization and hedging
A wind farm operator or utility designs customizable weather-risk hedges to stabilize income from existing PPAs.
When actual production falls short of contracted volumes due to adverse weather, hedging instruments offset the shortfall.
Powerup helps operators structure these instruments using indices, test their effectiveness across historical weather scenarios, and monitor positions against real-time conditions.

Portfolio risk assessment
Portfolio risk assessment
An investor or fund manager evaluates risk-adjusted returns across a renewable portfolio, comparing asset performance across geographies and technologies using long-term modeled production data.
Powerup provides the visibility needed to identify concentration risk, evaluate diversification benefits, and make acquisition or divestment decisions based on weather-driven performance patterns rather than assumptions.
