On the model configuration page for MUIO V5.6, the modes of operation was changed to 2 for HO8(Battery Storage), going forward, I like to confirm if the modes of operation should be left as 2 or changed to 1, please also share your reason(s), thanks ---

**Keep the modes of operation set to 2 going forward.** Here is the simple reason why: - **Mode 1 is for Charging:** The battery takes power _in_. - **Mode 2 is for Discharging:** The battery sends power _out_. A battery needs to do **two opposite things** (fill up and empty out). In OSeMOSYS, one mode can only do **one** thing. If you change it to 1, the battery will only be able to charge _or_ discharge, but not both. Hope it clears your concern. ---

Hello everyone, I’ve been finding it difficult to get the exact type of graphs found in the hands-on manual. For HO9, I have attached what I got after running the model vs the expected result in the manual. I would really appreciate if someone clarify what I’m not doing correctly ![Screenshot (118)](https://europe1.discourse-cdn.com/loughborough/original/1X/a933cd7f19d3fa44ebe393f4c4af0f684b4d2014.png) ![Screenshot (119)](https://europe1.discourse-cdn.com/loughborough/original/1X/93f355474902368d4c085a74750fbe9e343f72ad.png) please advise ---

Dear @Chikason, They remain at 2, since the battery will continue to be part of the model for the rest of the hands-on exercises in the course. ---

Dear @Chikason, Could you please share the ZIP file of your model so it can be compared? There could be several possible reasons for the issue. ---

Hello, I have attached the zip file as advised. I have had some difficulties with my hands-on results, thus slowing down my progress. Many thanks for your support (Attachment OSeHO9.zip is missing) ---

I guess I may not able to share the ZIP file here, I got this response after I tried Details: OSeHO9.zip: Sorry, the file you are trying to upload is not authorized (authorized extensions: jpg, jpeg, png, gif, heic, heif, webp, avif). Please advise, thanks ---

Dear @Chikason, I have compared the input files using AI and the differences are the following: **MINBIO, the biomass supply, is missing from the first file.** Nothing produces BIO there, so PWRBIO can’t run in that model. The correct file adds: - **TotalTechnologyAnnualActivityUpperLimit:** MINBIO = 30 every year. - **CapitalCost:** MINBIO = 0.001. - **VariableCost:** MINBIO = 7.1 in mode 1. - **OutputActivityRatio:** MINBIO produces BIO at 1. - **OperationalLife:** MINBIO 1 → 100. **CapitalCost:** - **PWRWND is shifted one year.** The first file starts at 0 in 2021 and ends at 995. The correct file runs 1450 (2021) to 960 (2035). As it stands, wind is free in 2021. - **PWRBIO:** 0.001 → 2200. - **MINHYD:** the first file has the year numbers (2021, 2022, … 2035) pasted in as costs. The correct value is 0.001. Please adjust the values accordingly and rerun the model. ---

many thanks @Fernando_Plazas , I will make the adjustments and revert.
