這是我們在2017年為美國university of Florida的學弟學妹們寫的一篇金融投資financial investment類論文，首先在開頭的部分介紹了文章的主要信息，壓縮天然氣（CNG）加氣站項目，P3引入在賓夕法尼亞州周圍的公共交通機構開發更清潔的壓縮天然氣站，如果由私人公司處理，運營可能更具成本效益。在壓縮天然氣工業中，P3有望實現多個目標，包括提供可靠的CNG燃料，提升設施以適應CNG，降低長期運營成本，並建立新的收入來源作為其他基礎設施改進的支持項目。
As for the compressed natural gas (CNG) fueling stations project, the P3s are introduced to develop cleaner CNG stations at public transit agencies around Pennsylvania, and the operation could be more cost-efficient if it is handled by a private company. There are several goals that is expected to be achieved by P3s in the CNG industry, including providing reliable access to CNG fuel, upgrading facilities to accommodate CNG, reducing long-term operations costs and establishing a new revenue source as a support for other infrastructure improvement projects.
然後是body部分的寫作，給出自己的觀點並且給出論據，提出該行業的主要公眾參與者是政府機構，即負責管理交通和能源的機構。 在這種情況下，賓州州DOT是公共部門的參與者。 它有權制定計劃並選擇可參與項目的P3。另一個公共部門的參與者是當地的運輸公司，他們將從P3購買CNG，然後將其用於公共交通。
The major public participant in this industry is the government agency, namely the ones that are in charge of administrating transportation and energy. In this case, the Penn state DOT is the public sector participant. It has the sole authority to make plans and choose the P3s that can participate in the project.Another public sector actor is the local transit agencies, who would purchase the CNG from the P3s, and then use it for public transportation. It can be seen that the public participant is also a customer of the P3s, while another government agency that is one level higher servers as a partner at the P3s.
最後的部分用一個conclusion進行全文的總結，就Penn CNG站項目而言，Penn DOT預計將為銷售給客戶的每加侖燃料賺取15％的版稅。Penn DOT在項目期限內獲得了至少210萬美元的版稅保證。此外，地方運輸機構預計每年可節省1000多萬美元。預計這個項目將在10年內值得花費，總儲蓄超過1億美元。
Yes, there is definitely a good prospect for decent returns for the P3s in the CNG stations project.In the case of the Penn CNG station project, the Penn DOT is expected to earn 15% royalty for each gallon of fuel that is sold to the customers. And Penn DOT has been given a guarantee of at least $2.1 million in royalties over the term of the project. Besides, the local transit agencies are expected to save more than $10 million per year. The project is expected to be worth the cost in 10 years with over $100 million in total savings.One other reason I believe the CNG stations project will be profitable is that as we are running out of gasoline, the price of fuel would increase as well. So, the price for the CNG will also rise, which can further reduce the cost for the local transit agencies. Besides, in this case, Pennsylvania has an abundance of natural gas, utilizing the resources owned by the state could reduce the dependency of imports of fuel, at the same time avoiding the fluctuations of its cost.
