Introduction The following report provides an introduction to the different procurement mechanisms and structures for Private Sector Participation (PSP) in the energy market. Chapter 2 provides an overview on some of the most important elements of private sector participation including the different project types and IPP models and bidding processes. In chapter 3 the Consultant suggests a suitable structure for such processes based on international best practices. The Annexes contain templates for a Power Pur- chase Agreement (PPA) Terms Sheet and Minimum Functional Specifications (MFS) for Wind Power, Solar Photovoltaic (PV) and Concentrating Solar Power (CSP). They provide an overview about the different legal and technological aspects that need to be covered in the actual project-specific context. 2. Private Sector Participation (PSP) The private and public sector can take different roles in the development of (renewable) energy pro- ject. Though there is large number of possible constellations, one typically distinguishes between the Equipment Procurement and Construction (EPC) model and the Independent Power Producer (IPP) scheme, the first one being the traditional concept, the latter growing since the 1990s. In an EPC scheme the typical role distribution is sketched below. Figure 1: Structure and Actors in EPC model The plant itself is on the balance sheet of the utility including the financing and Operation and Mainte- nance (O&M) risks. The technology risks are reduced for the utility through performance guarantees and warranties. The focus is typically on a cheap design allowing only a small range of technological optimization for the EPC. In an IPP scheme, the risks for financing, O&M and technology are shifted to the project company owning the plant, which is off the balance sheet of the utility. This model allows for more flexibility on the actual design optimization on the side of the IPP. Here, the IPP sells the electricity to the seller based on a PPA. There are a number of different IPP structures that share the concept of a privately owned energy production facility for some period along the project’s lifetime. They include: Libya: SPREL; Stage III PSP Transaction Documents LBY2560_TaskD_Stage III_PSP_Documents.docx  -3-  Build Operate Transfer (BOT): The facility is owned by the concessionaire/host. The investor pays for construction, concession, and is allowed to operate during concession period. After that the physical assets are being transferred to the state.  Build Own Operate Transfer (BOOT): The investor retains ownership, operating for a limited fran- chise period. After that the facility is transferred to the state.  Build Own Operate (BOO): Investor retains ownership, operating and open-ended franchise (rec- ommended, alternatively BOT).  Build Lease Transfer (BLT): Special Purpose Company (SPC) builds, leases and eventually trans- fers assets.  Build Lease Own (BLO): Same as above, but assets remain with project company. The IPP scheme focuses around the Special Purpose Vehicle (SPV) which is established only for the purpose of the renewable energy project. Its roles include entering into the contracts and financing, partnerships, joint ventures or other arrangements. Government agencies can hold shares of the SPV. As such the SPV will sign and administer the relevant agreements, such as PPA. See below the typi- cal framework for such an SPV structure. Figure 2: SPV Structure and Framework As a rather general rule the IPP contractual framework shall assign all risks of the project to the party best able to handle them. As such the PPA agreement defines the conditions for supply and selling of electricity from the SPV to the buyer (e.g. utility or industrial offtaker) including supply conditions, tar- iffs, guarantees and testing. The critical figure is the agreed tariff. For power projects it is typically split into a capacity payment for fixed O&M and capital cost recovery (debt service and shareholders’ r e- turn) and an energy payment for variable O&M recovery (fuel, spare parts, consumables and alike). For renewables fuel does not play a major role. For further detail on the typical elements of this central document please refer to the PPA Term Sheet in the annex. In addition to the PPA, the shareholder’s agreement rules the relationship of SPV’s shareholders and the nature of the SPV incl uding the distri- bution of liabilities and the scope of the SPV. The insurance agreement is supposed to protect the SPV from diverse losses due to events or natural disasters including coverage, deductibles, coverage period and extension. Aside from the legal agreements on selling the electricity, the management of the SPV and insurance, there are a few contractual arrangements required related to the access to grid, fuel, water and land. The grid connection agreement ensures the connection to the grid and transport of electricity defining Libya: SPREL; Stage III PSP Transaction Documents LBY2560_TaskD_Stage III_PSP_Documents.docx  -4- the connection point, technical restrictions and grid requirements. Fuel and/or water supply agree- ments guarantee the required fuel/water supply for the plant defining interfaces, quality specifications, prices and volumes. Regarding the three technologies in the focus of this report (solar PV, solar CSP, wind), this would only apply for CSP power plants. Finally, the actual construction and maintenance needs to be considered through O&M and EPC agreements. The latter guarantees that the construction of the plant through an EPC provider accord- ing to the specifications is on time. It includes the technical specifications, guarantee values, the turn- key price, payments, milestones and penalties. The O&M contract between the services provider and the SPV finally defines the rules for the proper and efficient operation of the plant including maintain- ing the availability and Key Performance Indicators (KPIs), the delivery of electricity and bonus/ malus payments. The EPC contract has a large influence on the final tariff and project costs (>80%). The contract can be turnkey lump-sum or lot-wise based on the risk assumptions of the SPV. In any case it is important that it is designed back-to-back with the PPA agreement. It should at least include the technical speci- fications, guarantee values, testing procedures and liquidated damages (LD). The O&M contract shall specify the guarantee values regarding availability, performance and consumption. Fees are perfor- mance-related and bonus/malus should cover the SPV’s operation risks. The O&M should be involved before Commercial Operation Date (COD). Developers and shareholders of SPV could take the role as an O&M service provider. 3. Procurement Process The procurement process for an IPP scheme is split into different phases. During a pre-qualification phase, the prospective bidders provide evidence for a set of qualification criteria typically divided into technical, financial and legal requirements. This Request for Prequalification (RfQ) takes place after a feasibility assessment and when a minimum development progress has been achieved including tech- no-economic analysis, verification of the availability of land and media, site accessibility, possible envi- ronmental impacts, grid connection and once no major issues with permitting and licensing were iden- tified. In short, a proper due diligence of requirements is necessary before going into procurement to avoid unnecessary delays and extra costs. Prior to the actual prequalification a simple Expression of Interest (EoI) may be used to sense the market interest in the project and the availability of potential bidders/consortia for a competitive pricing. This is recommended in the Libyan case. Libya: SPREL; Stage III PSP Transaction Documents LBY2560_TaskD_Stage III_PSP_Documents.docx  -5- Figure 3: Prequalification Process The main objective of the prequalification is to select only bidders/consortia with individual or added experience, capabilities and financial backing for developing and implementing the project (possible to include also EPCs and O&Ms), to provide the market with sufficient information about the project, to give confidence on its seriousness and to initiate the start of formation of associations/consortia. After the prequalification stage the shortlisted bidders get access to the bidding documents and re- quired studies/reports to prepare a competitive proposal (Request for Proposals, RfP). This should be a single set of documents for all bidders for fair, transparent and consistent evaluation and awarding. For IPP/PSP schemes complex legal, financial and technical requirements need to be engineered. Lo- cal and IFI’s regulations should be considered and national committees established to oversee bid process. Clear links and references throughout the documents are important to avoid duplication whenever possible. In the Libyan case only commercial/proven technology should be tendered and a developer chosen with sufficient financial capabilities, technical and regional experience (MENA). The bid strategy can be adapted to the market and technology. As stated above, the Expression of In- terest is optional for instance. Further, the bid procedure can be a single or a two stage process. The two-stage proposal is applied for a low level of certainty with regard to the specifications. In both cases the proposal can be based on one or two envelopes/packages for financial and technical offers. An IPP scheme is based on Minimum Functional Specifications (MFS) and the developer is free to opti- mize design and O&M for high availability as long as the output and operation conditions are fulfilled. Libya: SPREL; Stage III PSP Transaction Documents LBY2560_TaskD_Stage III_PSP_Documents.docx  -6- Figure 4: Example of CSP Bidding Process in Single Stage Bid Various aspects need to be considered in the bidding documents such as the track record of the cho- sen technology, the amount of local content, the involvement in the plant’s operation via an agency (GECOL, REAOL, REDEVCO, IPP Commission), minimum criteria for countries, manufacturers, sup- pliers or applicants, compensation structures (auction, fixed tariff...etc.), the evaluation scheme itself (points, major deviations) or how to deal with missing documents and clarifications during the process. The typical structure of the bidding documents is illustrated below. Figure 5: Bid Documents structure The Bid Evaluation itself should be based on the clarity for price optimization and plant’s optimization. Only substantially compliant bids will be considered for the evaluation according to price criteria (LCOE, tariff). The definition of criteria for substantial compliance should include:  Completeness of bid  References (already in RfQ, only if additional information is required) Libya: SPREL; Stage III PSP Transaction Documents LBY2560_TaskD_Stage III_PSP_Documents.docx  -7-  Financial standing (already in RfQ, only if additional information is required)  Technical: HSSE, performance, costs, operational, standards, perf. Model  Work schedule proposed is realistic  Exclusions or modifications to the draft agreements  Local requirements  Requirements on manufacturers and suppliers of MAIN equipment  Compliance of warranties, insurances Before the Notice to Proceed (NTP) there are a few final steps. First final clarifications and negotia- tions take place with the best-ranked bidder. If this does not succeed, this will be continued with the second best ranked bidder and so on. This is followed by the preparation of final contracts on all as- pects. In particular the PPA contract is prepared and final parts of the RfP migrate to PPA sections and annexes. Contracts are signed, financial close achieved and conditions precedent to NTP fulfilled. Eventually a provisional NTP could be issued to start engineering and wait for permitting and licensing to be finalized Finally, the plant’s acceptance is of foremost importance to guarantee expected production levels of the plant and cash flow. It includes three main stages, provisional acceptance, final acceptance and Full Commercial Operation. Typically the SPVs are penalized if they don’t sell the energy as specified in the PPA. For a PSP scheme minimum requirement for EPC and O&M would be required due to shared ownership, risk and responsibilities which should be back-to-back with the PPA contract as stated above. Most importantly guarantee values and payment structures need to be defined.

Power Purchase and Sale 26 Solar electricity  The base year (20XX) annual electricity generation is XX MWh per generation year] based on the mean (P50 probability) Solar Irradiation and other data compiled as “Typical Meteorological Year”.  Based on variability of solar resources, the generation of electricity during any individual year can vary by +/- 10% compared to the base year.  A degradation of output of the installed PV modules of [0.5% per year] shall reduce the base year electricity generation  The minimum solar electricity generation availability guaranty by SELLER in the base year is XX MWh (90% of annual mean solar PV generated electricity) based on a P99 probability of solar resource. The guaranteed electricity generation considers scheduled and un- scheduled outages of the PVPP.  The solar electricity generation refers to the potential production dur- ing a full year (365 days), not counting days where the BUYER does not consume electricity from the PVPP. 27 Liquidated Dam-  On annual basis, SELLER and BUYER shall review the electricity ages for SELLER generated by the PVPP.  In case the solar electricity generation is less compared to the mini- mum guaranteed electricity generation, Liquidated Damages apply for the undersupplied amount of generation, the generation deficit.  For this generation deficit, SELLER shall reimburse to BUYER the dif- ference between the average Name of Utility tariff (daytime) and the PV tariff (both applicable for the respective calendar year) for the un- dersupplied amount of kWh/a 28 Electricity off-take  BUYER shall guarantee to buy at least 90% of annual solar PV gen- erated electricity, independent from the actual consumption of the BUYER.  BUYER guarantees to take all electricity generated by the PVPP at all times according to the load of the BUYER.  the BUYER shall consume electricity from the PVPP with priority over electricity supply from other sources (i.e. Name of Utility) 29 Liquidated Dam-  BUYER shall reimburse SELLER for every kWh that could be pro- ages for BUYER duced by the PVPP but was not consumed from the BUYER at times where the load of the BUYER has been high enough to consume the Libya: SPREL; Stage III PSP Transaction Documents LBY2560_TaskD_Stage III_PPA_Term_Sheet.docx  -7- PVPP energy. 30 Deemed Electrici-  Deemed electricity is considered as delivered at times when the ty Amount PVPP is available to generate electricity, but the BUYER operations are shut down or at reduced load.  The amount of deemed electricity is calculated as the sum of reduced load over the applicable period of time against the capacity of the PVPP for the applicable period of time under given solar Irradiation conditions.  Payment of deemed electricity is only applicable in case actual elec- tricity-off-take from the BUYER is below the guaranteed Electricity off- take, and is applicable for the difference between actual and guaran- teed electricity off-take. 31 Price  The initial price shall be XXX Currency/MWh (base case) calculated for a start of operation in the year 2016. Due to uncertainties in several project parameters, the initial price is ad- justed accordingly: Base Case (XXX Currency/MWh) + upgrade of Name of Utility grid connection [XX million Currency] + additional effort to clean PV modules (based on the BUYER dust survey data) + additional effort to clear site (invader bush) = XX Currency/MWh Depending on the final results of a geotechnical analysis, the foundation technology and the corresponding PPA price is adjusted as following: a) Pile driving / ramming: XXX Currency/MWh b) Screw driving: XXX Currency/MWh c) Concrete foundation: XXX Currency/MWh The base case guaranteed electricity off-take is 90% of annual solar PV generated electricity. If the guaranteed amount is lowered, we pro- pose to step up the pricing as follows (assuming pile driving technol- ogy is feasible): 90% guaranteed off-take: XXX Currency/MWh 80% guaranteed off-take: XXX Currency/MWh for the first 80% per year, any additional electricity XXX Currency/MWh (weighted annual elec- tricity price XXX Currency/MWh) 70% guaranteed off-take: XXX Currency/MWh for the first 70% per year, any additional electricity XXX Currency/MWh (weighted electricity price XXX Currency/MWh) 60% guaranteed off-take: XXX Currency/MWh for the first 60% per year, any additional electricity XXX Currency/MWh (weighted electricity price XXX Currency/MWh) Optional: An extension of the PPA term can reduce the PPA price as fol- lows: 15 years PPA: XXX Currency/MWh (90% guaranteed off-take) 20 years PPA: XXX Currency/MWh (90% guaranteed off-take) 25 years PPA: XXX Currency/MWh (90% guaranteed off-take) Libya: SPREL; Stage III PSP Transaction Documents LBY2560_TaskD_Stage III_PPA_Term_Sheet.docx  -8-  Price excludes VAT or other applicable taxes in Country 31 Tariff and other  Early Operating energy payments charges  Energy Payments after contract period 32 Price Indexation  Escalation of PPA tariff in year 1 to 3 equivalent to Name of Utility tar- iff increase  Escalation of PPA tariff in year 4 to 15 the electricity price shall be in- creased according to the Consumer Price Index (CPI) minus 1% of Currency.  st The new price shall enter into force from 1 of July of each year, based on the official Currency CPI and Name of Utility tariff adjust- ments. 33 PPA term  The PPA shall be valid for a 15 year term, commencing with commer- cial operation date (COD).  An extension of the PPA after completion of the above period at re- vised prices shall be mutually agreed. 34 End of Term  At the end of the term, the BUYER has the right to choose one of the following options: a) Negotiate a new PPA contract with the SELLER b) The SELLER shall hand-over the PVPP at no costs c) Dismantle of PVPP and rehabilitation of area at its own costs. 35 Electricity sales to  SELLER aims to sell excess electricity not consumed by the BUYER Name of Utility to Name of Utility.
