Energy storage systems (ESS) can increase renewable power integration. • We consider ESS investment risks and options to offset these risks. • The real option analysis (ROA) values the waiting for a reduction of risks. • The implementation of the ROA increases the economic performance of ESS. •
In addition, the value and the uncertain level of incentives would have a major impact on the profitability of the energy storage. Other important risks affecting the NPV of storage systems are the construction delay and cost overrun. These two risks have a very high impact on the profitability and high probability to occur.
While a comparable asset class in 2009 was a corporate bond of an established and listed company, today it is a low-risk infrastructure investment. The overall decline of risk premiums and the technology difference in that decline (stronger in solar PV than onshore wind) are consistent with other findings for Germany.
[With solar PV, in contrast,] replacing one or two modules only leads to a row of modules not producing electricity”. In sum, risk premiums – measured with different indicators – and investment risk decreased substantially for solar PV and onshore wind in Germany, Italy and the UK between 2009 and 2017.
Onshore wind and solar PV investment risk is studied in Germany, Italy and the UK. Investment risk and risk premiums have declined between 2009 and 2017. Policy and technology risks have become relatively less important. Curtailment and price risks have become relatively more important.
The empirical literature on RET investment risk can be divided into two streams. The first aims to develop a better understanding of investor behaviour by shedding light on trade-offs, decision metrics (including risk) and biases.
As investors typically did not have experience with RET projects in the early years, they assembled skilled teams with the capability to assess the technological risks of onshore wind and solar PV. In turn, risk assessments became more precise and risk margins decreased.
