| MESSAGE models the time horizon 1990 to 2110 in 5- and 10 year time steps where the first 5 periods (1990, 1995, 2000, 2005, 2010) are 5-year periods and the remaining 10 periods are 10-year periods (2020, 2030, 2040, 2050, 2060, 2070, 2080, 2090, 2100, 2110). The first four periods up to 2005 are fully calibrated, i.e. the model has no flexibility to change in these five periods. The 2010 period is partly calibrated so far, some recent trends are included in this time period, but some flexibility remains. In scenario applications the 2010 period is typically fixed to its baseline development so that future climate and energy policy cannot induce changes in the past. The reporting years are the final years of periods which implies that investments that lead to the capacities in the reporting year are the average annual investments over the entire period the reporting year belongs to. | |||

| MESSAGE can both operate perfect foresight over the entire time horizon, limited foresight (e.g., two or three periods into the future) or myopically, optimizing one period at a time (Keppo and Strubegger, 2010 :cite:`keppo_short_2010`). Most frequently MESSAGE is run with perfect foresight, but for specific applications such as delayed participation in a global climate regime without anticipation (Krey and Riahi, 2009 :cite:`krey_implications_2009`; O'Neill et al., 2010 :cite:`oneill_mitigation_2010`) limited foresight is used. | |||

Could be useful to add links to the respective parts of the MESSAGEix documentation where foresight is discussed.

Thanks @volker-krey for this, I added a link to the mathematical formulation.

| The global MESSAGE model includes a single annual time period within each modeling year characterized by average annual load and 11 geographic regions. | ||
| Seasonal and diurnal load curves and spatial issues such as transmission constraints or renewable resource heterogeneity are treated in a stylized way in the model. | ||
| The mechanism to represent power system reliability in MESSAGE is based on (Sullivan et al., 2013 :cite:`sullivan_electric_2013`). This method elevates the stylization of temporal resolution by introducing two concepts, | ||
| peak reserve capacity and general-timescale flexibility (for mathematical representation see this 'Section <https://message.iiasa.ac.at/en/stable/model/MESSAGE/model_core.html#system-reliability-and-flexibility-requirements>`_). To represent capacity reserves in MESSAGE, a requirement is defined that each region build sufficient firm generating capacity to maintain reliability through reasonable load and contingency events. As a proxy for complex system reliability metrics, a reserve margin-based metric was used, setting the capacity requirement at a multiple of average load, based on electric-system parameters. While many of the same issues apply to both electricity from wind and solar energy, the description below focuses on wind. |

In the web page, the link appears as it is written in the code: 'Section https://message.iiasa.ac.at/en/stable/model/MESSAGE/model_core.html#system-reliability-and-flexibility-requirements`_).

Thanks @GamzeUnlu95, the typo is corrected now.

The link for the database can not be clicked and the reference appears with the 'cite' command but not as a number.

Thanks for noticing this @GamzeUnlu95. The link to database corrected. Can you please mention which reference is not working?

It was ''rogner_chapter_2012''. But it seems to be working now.
