PLEXOS® for Renewables

The world's most powerful energy market simulation engine providing analytics and decision-support to modelers, generators, and market analysts across the whole Renewables lifecycle.


empowering transformative energy decisions

Supporting decisions across the Renewables lifecycle

  1. Phase 1

    Market Analysis

    As renewable auctions become more competitive, developers are looking towards international expansion, and revenue streams with greater market exposure to finance projects.
  2. Phase 2

    Investment Decision

    Developers are faced with many potential projects, each with their own unique challenges and opportunities investment decisions are taken by comparing the relative risks and rewards.
  3. Phase 3

    Project Siting & Sizing

    While traditionally developers have focused 
    exclusively on weather profiles for siting and sizing projects, there is an increasing emphasis on market impacts, such as curtailment and price cannibalization.
  4. Phase 4

    Trading & Hedging

    Many options exist besides PPA. Developers explore the relative benefits of these instruments and revenue streams, both during project financing, and potentially ongoing trading activities.
  5. Phase 5

    Operate Assets

    As renewable market share increases, there is trend towards the operation of a more diverse portfolio, often via renewables and storage technologies, in order to provide round the clock availability and take advantage of peak time pricing.
  1. Phase 1

    Market Analysis

    Energy market price forecasting in PLEXOS is based upon a fundamental model in which both the supply side and demand sides are modelled. PLEXOS models in detail both the technical and commercial characteristics of both existing assets, as well as technology candidates for investment. Click here to read more.

    How does PLEXOS help?

    Models market participant behaviour across all time frames

    • Sub-hourly decisions

    PLEXOS models the energy market clearing process by optimizing the supply and demand for every market clearing period, providing energy price forecasts and renewable capture prices.

    • Mid-term operational decisions

    Accurately simulate markets where longer term operational considerations are key, such as hydro heavy markets, as well as the impact of other long duration storage options such as hydrogen.

    • Long-term expansion decisions

    Develop future energy market Scenarios through simulating investor behaviour by considering the capital costs of potential new entrants to the market in order to automaticity determine the forecasted capacity mix. 

    Simulation Ready Data
    Energy Exemplar provides simulation ready data sets for energy markets across the globe, to allow you to start analyzing the future energy markets on day 1.  

    Single unified engine for consistent decisions
    Integrate all of this analysis into a single engine, with all phases of simulation interacting seamlessly with one another.

  2. PHASE 2

    Investment Decision

    PLEXOS offers a convenient way to screen potential projects and understand the return on investment of those projects. Users can either
    evaluate a specific project or provide a number of candidate projects with capital and operating costs and have PLEXOS determine the optimal investment strategy. Click here to read more.

    How does PLEXOS help?

    Project Screening  
    Given a potential set of technology alternatives, PLEXOS determines the optimal selection of technologies and relative installed capacities to maximize project profitability. PLEXOS unique stochastic optimization methodology allows for consideration of uncertainty in climatic conditions. 

    Hydrogen & Emerging technology Analyze the investment opportunities associated with renewable & hydrogen

    Battery Investment Projects
    PLEXOS allows for the optimal schedule and dispatch of a mixed portfolio containing traditional assets, renewable assets, batteries and demand side management.

    Gross-margin capture 
    Provide detailed gross margin reporting of any asset, project or portfolio  considering the participation within all revenue streams such as day ahead, balancing and ancillary services markets.

  3. PHASE 3

    Project Siting & Sizing

    Given a set of project objectives, PLEXOS will automatically determine the optimal size and location of an asset or set of assets. Click here to read more.

    How does PLEXOS help?

    Optimal Project Sizing
    PLEXOS will determine the optimal size of an asset to meet a given objective, subject to any constraints. An example could be the optimal sizing of a renewable & storage project to meet availability requirements of a defined PPA. 

    Net Zero energy system design 
    PLEXOS can be used to determine the cost-optimal energy system design required to meet a given decarbonization objective for a heavy energy consumer. 

    Managing basis risk
    When siting a renewable project, the developer must consider both the generation potential at that site, as well as the basis risk., PLEXOS is able to consider grid location when making investment decisions, considering both hub-node differentials as well as congestion risk.

  4. PHASE 4

    Trading & Hedging

    PLEXOS supports market traders to value their portfolio and analyze risk associated with uncertain conditions in the market at market level and portfolio level. Click here to read more.

    How does PLEXOS help?

    Evaluate Marchant Risk
    PLEXOS risk analysis can be undertaken both at market level, providing a spread of possible market prices, as well as at portfolio level allowing computation of typical risk metrics such as VaR and PaR

    Evaluating Power Purchase Agreements
    PLEXOS enables renewable developers and operators to understand what a fair price for a Power Purchase Agreement (PPA) is or evaluate the relative merits of a PPA vs energy market participation. Further, PLEXOS can support the development of PPA tariffs during tendering process’.  

    Develop hedging strategies
    PLEXOS allows the user to provide determine the optimal hedge based upon a given Conditional Value at Risk (CVaR). The model can also consider subsidy mechanisms such as Contract For Differences or financial instruments.

  5. PHASE 5

    Asset Operation

    PLEXOS optimizes the dispatch of a portfolio to either minimize the cost of meeting an existing trade position or maximize the profitability of a
    portfolio under given market conditions. PLEXOS will fully co-optimize the renewable assets along with any storage and traditional generation assets. Click here to read more.

    How does PLEXOS help?

    Energy & Ancillary Services co-optimization
    For assets, such as batteries, which can provide both energy and system services, PLEXOS optimizes the use of the battery for energy provision vs provision of the ancillary services. PLEXOS co-optimizes against all AS products.

    SCADA integration 
    PLEXOS can be integrated directly to real time control system such as SCADA EMS. Here the current operating conditions are passed to PLEXOS as initial status, and PLEXOS runs an economic dispatch optimization over the coming hours/days.

    Second level resolution
    PLEXOS supports resolution as low as one second. While traditional generation is generally dispatched on an hourly basis, the
    intermittency associated with renewable generation calls for a lower level
    of dispatch resolution.
