Kokonaiskestäviä ratkaisuja käytöstä poistuneille turvemaille Etelä-Savossa (KORTES) KC, Raghu; Luhas, Jukka; Shrestha, Pallav; Gyawali, Arun; Ranta, Tapio Tämä on tutkimusraportti Lappeenrannan-Lahden teknillisen yliopiston LUT ja Helsingin-yliopiston tuottamalle ryhmähankkeelle: Kokonaiskestäviä ratkaisuja käytöstä poistuneille turvemaille Etelä-Savossa (KORTES). Ryhmähankkeen to-teutusaika oli 1.9.2023–31.12.2025. Hankkeen tavoitteena oli arvioida käytöstä poistettujen turvemaiden uudelleen-käytön kokonaiskestävyyttä Etelä-Savossa. Turvemaiden jälkikäyttöön liittyy usein useita vaihtoehtoja, kuten uudelleenvetäminen, ekologinen ennallistami-nen, kosteikkoviljely, metsitys sekä muut passiiviset hoito- ja käyttömuodot. Näillä vaihtoehdoilla on omat vahvuutensa ja heikkoutensa, ja niiden kokonais-kestävyyden arviointi, erityisesti ympäristöllisten, taloudellisten ja sosiaalisten ulottuvuuksien näkökulmasta, on välttämätöntä. Tällöin käytöstä poistettuja tur-vemaita koskeva päätöksenteko voi perustua kokonaisvaltaiseen tietoon. Raportissa tarkastellaan sosiaalisesti ja ympäristöllisesti kestävää siirtymää pois turpeen käytöstä Etelä-Savossa. Siinä kartoitetaan entisiä turvetuotantoalueita, jotka edellyttävät maankäytön ja -hoidon suunnittelua, sekä arvioidaan mahdol-lisia jälkikäyttövaihtoehtoja ja niistä saatavia tuotteita, kuten ruokohelpeä eläin-kuivikkeena sekä pajupohjaista energian ja biohiilen tuotantoa. Lisäksi raportissa analysoidaan käytöstä poistuneilla turvemailla tuotettavien vaihtoehtoisten bio-massojen taloudellista kannattavuutta ekotehokkuusindeksin avulla sekä tarkas-tellaan niihin liittyviä sosioekonomisia vaikutuksia.; This is the research report for a group project ‘Overall sustainability assessment of after use solutions of cutaway peatlands in South Savo’ produced by Lappeenranta-Lahti University of Technology LUT and University of Helsinki. The implemen-tation period of the group project was 1.9.2023–31.12.2025. The project aimed to assess the overall sustainability of reuse of phased-out peat-lands in South-Savo. Often many alternatives such as rewetting, ecological resto-ration, wetland cultivation (paludiculture), reforestation and other passive manage-ment options. These options have pros and cons in their own accord and their over-all sustainability, i.e. environmental, economic and social dimensions of sustaina-bility, is necessary to determine the best decision making about the phased-out peatlands. The report evaluates a socially and environmentally sustainable transition away from peat in South Savo. It maps former peat production areas requiring land man-agement and reviews potential post-use options and products, such as reed canary grass for animal bedding and willow-based energy and biochar production. In ad-dition, the report assesses the economic feasibility of alternative biomass produc-tion on abandoned peatlands using eco-efficiency index and examines the associ-ated socio-economic impacts.

Analysis of Truck Electrification in the Port of Mussalo Saleem, Ahmed; Haakana, Juha; Aarniovuori, Lassi; Kauranen, Pertti This report presents an assessment of external truck traffic estimation associated with Mussalo Port and examines the implications of partial electrification of heavy-duty freight vehicles for charging infrastructure demand and electricity grid capacity. The study is based on traffic observations obtained from Fintraffic Traffic Measurement Stations (TMS) located along the logistics corridors that serve the port area. These stations provide raw data containing vehicle movement constraints. To address these data constraints, the analysis applies an inference-based framework to identify truck movements that are associated with port activity. The traffic dataset is first restricted to heavy vehicles, and passenger cars and light-duty vehicles are excluded. This filtering step aligns the dataset with the focus on freight transport and charging demand. Following this, truck movements are inferred through probabilistic matching between pairs of traffic measurement stations. Matching is performed statistically using constraints and feasible travel time windows derived from known distances between stations. Truck observations that satisfy these conditions across multiple stations are treated as matched movements along logistics corridors, while observations that do not satisfy these conditions are classified as unmatched traffic. The matched truck flows are further processed to identify vehicles that can be considered candidates for battery-electric operation. This screening is based on vehicle class, haul length, and duty cycle assumptions. Electrification scenarios are constructed using class-wise adoption assumptions rather than a single penetration rate applied across all vehicles. This approach allows electrification to be represented in terms of absolute truck counts rather than aggregated percentages. Charging demand is estimated for the electrified truck subset using assumptions related to battery capacity, state of charge at arrival, target state of charge after charging, charging efficiency, and charging frequency. Two charging cases are evaluated to represent different operational conditions. For each case, annual energy consumption and peak power demand are calculated at the site level. The results indicate that peak power demand, rather than total annual energy consumption, determines charging infrastructure requirements and grid connection constraints at Mussalo Port.

Teollisen energiayhteisön mahdollisuudet Mussalon satamassa Haapaniemi, Jouni; Haakana, Juha; Honkapuro, Samuli Tässä raportissa analysoidaan teollisen energiayhteisön muodostamista satamaympäristössä. Raportissa analysoidaan paikallisen aurinkosähkötuotannon yleistymisen vaikutuksia paikalliseen kuormitusprofiiliin ja sähkönjakeluverkon kustannuksiin. Yhtenä vaihtoehtona teollisen energiayhteisön muodostamiseksi analysoidaan suljetun jakeluverkon muodostamista satama-alueelle. Analyyseissa hyödynnettiin satama-alueen sähköverkko- ja sähkönkulutusaineistoja. Tutkimuksessa havaittiin, että satama-alueen sähkönkulutus painottuu voimakkaasti talviaikaan, minkä vuoksi aurinkosähkön positiiviset vaikutukset sähköverkon kustannuksiin jäävät vähäisiksi, häviöiden pienentyessä maltillisesti. Tutkimuksessa analysoitiin paikallisen sähkönjakeluverkon kustannuksia sekä sähkönkulutusaineistojen perusteella muodostuvia verkkopalvelumaksuja, minkä perusteella havaittiin alueellisen tason kustannusvastaavuuden olevan kunnossa. Tämä kuvastaa sitä, että paikallisen suljetun jakeluverkon muodostaminen ei todennäköisesti johtaisi nykyistä matalampiin verkkopalvelumaksuihin satama-alueen asiakkaille. Tarkastelemalla sähkönkulutusaineistojen perusteella aurinkosähköjärjestelmien omakäyttöastepotentiaalia havaittiin, että kuormien summaamisen hyödyt omakäyttöasteen näkökulmasta jäävät satama-alueella maltillisiksi. Satama-alueella osa sähkönkulutuksista pystyisi hyödyntämään aurinkosähköä paikallisesti hyvällä omakäyttöasteella, mutta satamaympäristössä aurinkosähkölle soveltuvat asennuspinta-alat eivät välttämättä sijaitse samassa paikassa kuin soveltuva sähkönkulutus.; This report analyses the formation of an industrial energy community in a port environment. The report examines the effects of increasing local solar power production on the local load profile and on the costs of the electricity distribution network. As one option for forming an industrial energy community, the report analyses the establishment of a closed distribution network in the port area. The analyses utilized electrical network and electricity consumption data from the port area. The study found that electricity consumption in the port area is strongly concentrated in the winter season, which limits the positive effects of solar power on the costs of the electricity network, as the reduction in losses remains moderate. The study examined the costs of the local electricity distribution network as well as the network service fees derived from electricity consumption data, and based on this, it was found that the cost-reflectiveness at the regional level is in order. This indicates that establishing a local closed distribution network is unlikely to result in lower network service fees for customers in the port area. By examining the self-consumption potential of solar power systems based on the electricity consumption data, it was observed that the benefits of aggregating loads, from the perspective of self-consumption, remain modest in the port area. Some electricity consumers in the port could utilize solar power locally with a good self-consumption rate, but in the port environment, suitable installation surfaces for solar panels do not necessarily coincide with the locations of suitable electricity consumption.

Fast Expert Teams : A new way to collaborate Blomqvist, Kirsimarja We humans have a tremendous amount of valuable knowledge through education, work, and life experiences. Each individual holds unique knowledge and expertise, shaped by their distinct learning paths. Despite the depth and breadth of human knowledge, many organizational and societal challenges remain unresolved, and opportunities slip by. Within organizations, knowledge and expertise are frequently underutilized, leaving valuable insights untapped. Moreover, many organizations tend to operate within their own boundaries, even when the knowledge needed to solve complex tasks is distributed among individuals working in different organizations. When diverse individuals collaborate to co-create new knowledge, they draw from their collective human knowledge, which becomes most valuable when solving complex tasks requiring diverse expertise and contextual understanding. Problems and untapped opportunities become solutions when people have the motivation to participate and are enthusiastic about working together. Sharing human knowledge and co-creating new solutions across boundaries requires supporting structures, processes, and leadership. FET collaboration creates value for individuals, organizations and society. In short term, it enables mutual learning and provides access to resources that might otherwise be difficult to obtain. In the longer term, it strengthens social and human capital by connecting previously unfamiliar parties and enabling them to collaborate on complex missions or tasks of shared Interest. This guidebook focuses on building temporary expert communities and teams to tackle complex societal and organizational challenges with human collective knowledge.
