Technical regulations: Allowable voltage, frequency, THD variations Protective relays – 1-line diagrams for all cases: Induction Synchronous Inverters Single/multiple Connecting at different voltage levels (LV or MV) Communication channels Commercial regulations: Definitions of renewable energy, and efficient cogeneration Cost allocation Principle of standardized tariff determination Invoicing and payment arrangements Arbitration $ + Standardized Power Purchase Agreement (PPA)

Evolution of Thai VSPP regulations 2002 – VSPP regulations drafted, approved by Cabinet – Up to 1 MW export, renewables only – Tariffs set at utilitys avoided cost

Evolution of Thai VSPP regulations 2002 – VSPP regulations drafted, approved by Cabinet – Up to 1 MW export, renewables only – Tariffs set at avoided cost (bulk supply tariff + FT) 2006 – Up to 10 MW export, renewables + cogeneration – Feed-in tariff adder (premium payment) Paid by ratepayers – If > 1 MW then utility only pays for 98% of energy (utility incentive to facilitate VSPPs)

Jun 2009 Thailand VSPP Status

Dec 2009 Thailand VSPP Status

Mar 2010 Thailand VSPP Status

July 2010 Thailand VSPP Status 847 MW online PPAs signed for additional 4283 MW

Current VSPP challenges & responses ChallengeResponse 1. PPA speculatorsBid bond (200 baht/kWh) ($6/kW). No adder if >1 yr past Scheduled Commercial Operations Date. Solar online: 16 MW online Solar PPAs: 1784 MW

ChallengeResponse 2. Little diversity (generators online mostly >1 MW biomass owned by sugar, rice mills) 4% interest loans up to 50 million baht ($1.6 million) per project. Government loaned 4 billion baht ($133 million) to 13 banks at 0.5% interest.

ChallengeResponse 3. VSPP not well integrated into Power Development Planning (PDP) process Not much yet, but Thai NGOs have developed/advocate alternative PDP GWh Fuel mix in power generation Power Development Plan

Reflections -- Thai VSPP Low-key, local approach kept utilities from being threatened Thailands path to full generation-cost FIT started successfully with tariffs based on avoided cost Initial trickle of applications gave utility time to build capacity to implement program Feed-in adder very successful in attracting projects Incentivize utility (utility pays for only 98% of energy from projects >1 MW) Challenges arising as program grows, largely being addressed

Tanzania

Evolution of Tanzania SPP regulations Approved by regulator August 2009 Up to 10 MW export, renewables & cogeneration SPP Tariffs at average of long run marginal costs (LRMC) and short run (SRMC) – Grid-connected SPP tariff (2010): TZS ($0.074)/kWh TZS ($0.088)/kWh dry-season Aug-Nov TZS ($0.0663)/kWh wet-season Jan-Jul, December – In rural mini-grid areas offsetting diesel (2010): TZS ($0.24.6)/kWh 4 PPAs signed by November for English versions of regulations, and model PPAs

Tanzania SPP Legislative Framework National Energy Policy, 2003 Rural electrification policy statement Energy and Water Utilities Regulatory Authority Act – Establishing EWURA Rural Energy Act (2005) – Establishing REA & REF The Electricity Act, 2008

Legislative Framework, cont Energy Policy Statement No. 36 Establish norms, codes of practice, guidelines and standards for renewable energy technologies, to facilitate the creation of an enabling environment for sustainable development of renewable energy sources

Legislative Framework, cont The Electricity Act (2008) provides for SPPA and SPPT Definitions Standardized Small Power Purchase Agreement (SPPA): Means agreement between utility entity and a developer entered for pursposes of selling power to the grid not exceeding 10 MW but not less than 100 kW. Standardized Small Power Purchase Tariff (SPPT): Means the tariff agreed on in the SPPA License exemption for projects less than 1 MW (generation or distribution)

A goal: Light-handed regulation 1.Minimize amount of information that is required. 2.Minimize the number of separate regulatory requirements and decisions. 3.Use standardized documents, and make use of documents used by other agencies, to the maximum extent possible (reduce need for case- by-case negotiation)

Standardized Tariff Methodology for the Sale of Electricity to the Mini-grids Under the Standardized Small Power Purchase Agreements Tariff calculations for year 2009 Detailed Tariff Calculations under the SPPA for the Main Grid for year 2010 Detailed Tariff Calculations under the SPPA for the Mini-grids for year 2010 = Approved and available at: = Awaiting final approval and gazetting (public consultation completed)

Tariffs determined by SPP type 39 Connected to main grid Connected to isolated mini-grid Selling wholesale (to DNO*) Case 1Case 2 Selling retail (directly to final customers) Case 3Case 4 * DNO: Distribution Network Operator (currently TANESCO)

Tariff Case 1: Selling Wholesale to Main grid 40 Where C lrmc is the long run marginal cost as defined by Tanescos long-term power plan; and C srmc is the budgeted cost of thermal generation in the next year. Note: the actual calculations are somewhat more complicated, taking into account: Transmission losses Seasonality Price floor & cap They are available in: Standardized Tariff Methodology Under the Standardized Small Power Purchase Agreements available from EWURA. Order on Dec Tariff – case 1: Main Grid Tariff 2009 (TZS/kWh Tariff 2010 (TZS/kWh) Annual Average Dry season (Aug – Nov) Wet season (Jan-Jul and Dec) Note: $1 US = 1497 TZS (November 2010)

Tariff Case 2: selling wholesale to a mini- grid 41 Mini-grid SPP receives the average of Tanescos main grid and mini-grid avoided costs. C LmrcGrid = long run marginal cost for grid-power (adjusted for losses) C AveMini = average incremental cost of mini-grid power (levelized cost of electricity from a new mini-grid diesel generator). Tariff – case 2 (2009)Tariff 2009 (TZS/kWh) Tariff 2010 (TZS/kWh) Tariff (no seasonal variations) Note: $1 US = 1497 TZS (November 2010)

Tariff Cases 3 (isolated) and 4 (main grid): selling at retail to end use customers Tariff is proposed by SPP generator, subject to EWURA review – Less oversight demanded in cases in which community is in agreement with proposed tariff – Where possible, EWURA draws on financial analysis submitted to REA for rural electrification subsidy 42

Necessary permits, clearances and procedures for application 43 EWURA license Business license, tax registration, etc. Power Purchase Agreement (PPA) Land title or lease Resource Rights (e.g. water rights from River Basin Water Office) Letter of Intent (LOI) Environmental and Social Clearance (NEMC) Building Permit Sequence is important to avoid competing claims on project sites

5. Challenges / Opportunities 50

Challenges Challenge Inadequate financial resources to support the initiative Inadequate private sector participation in investment High interest rates loans from commercial banks Land ownership and water rights for SPPs projects especially wind farms & mini-hydro plants Low Tariff and non-cost reflective Response WB has established a facility, engage interest of other financial institutions Conducive Environment, rules and publicize Promote other sources mix grant and loans Include land ownership & water rights in RE Policy Adapt policy in future?

Challenges …..cont. 2 Challenge Lack of experience of key project promoters with skills in project management Lack of Renewable Energy Policy Lack of interest on the part of potential Off-takers (TANESCO) Response Capacity building (REA) Government needs to set policy targets, etc. Improving through regular discussions with utility

Reflections Renewable Small Power Projects can enhance efforts towards electrification of Rural areas Though generally expensive SPPs can be developed much faster hence increase capacity Private investments can be quickly organised and also benefit local entrepreneurs Light handed regulation will reduce regulatory burden hence benefit both investors and the country Good Policy, Cost reflective Tariff and well designed FiT can attract foreign and local investors 53
