examples to quantify non-market benefits and costs

benefits

  • time savings (=value of users' time * number of users withing a defined time period)
  •  

cost:

  • installation to avoid a e.g. noise problem
  • Willingness-to-pay (WTP)
  • Willingness-to-accept (WTA)

    • Methods for determining WTP and WTA

      • Travel cost method

      • Contingent valuation

      • Conjoint analysis

describe main challenges of utilities in Europe

  • increasing competition
  • transition to RE
  • Need to invest in grids and power plants
  • pressure to innovate

--> highest challenge is brought by the low energy wholesale prices (--> no technology without cost coverage)

Falling revenues and market values for large Utilities and for regional, smaller utilites falling cost of electricity on EU wholesale market

Which are the business model patterns and added values most suitable for Decentralized Energy Systems?

The Solution Approach:

  • identify Business Model Ideas suitable to DES
  • Verify suitability through simulations and feedbacks from DES stakeholders
  • dentify success factors
  • Define guidelines

Storage benefit to industry:

energy savings

waste heat recovery

Storage benefit to industry:

investment cost savings

downsized process equipment (new plants only)

Storage benefit to industry:

other fixed cost savings

reduced peak energy demand and connection fees (e.g. gas network)

Storage benefit to industry:

incresed availability and reliability

reserve capacity in case of interrupted energy supply or process failure

Storage benefit to industry:

operational flexibility

temporary capacity increase (de-bottle necking) or faster demand response

Storage benefit to industry:

energy load shifting

buy cheap - use when expensive (power to heat applications)

Storage benefit to industry:

power market revenues

offer services in power reserve market (power to heat applications)
