Gov’t to change renewable energy mix

Inquirer News, November 1st, 2012

The Department of Energy (DOE) is planning to reallocate the installation targets among the renewable energy sources in favor of the more expensive solar and wind power projects.

Energy Undersecretary Jose Layug Jr. assured the public, however, that such an action would not increase the feed-in-tariff (FIT) allowance—or the universal levy to be collected from all power consumers for the use of renewable energy facilities—beyond the estimate of 5 centavos per-kilowatt-hour (kWh).

The DOE has set a limited installation target of 760 megawatts. This means that only those projects that receive an allocation from this installation target—which refers to the total capacity of renewable energy projects that will be allowed to be constructed within a three-year period—will be subject to the feed-in-tariff rates.

Under the current installation target, the 250 MW has been allocated for hydropower projects, 250 MW for biomass, 50 MW for solar, 200 MW for wind power and 10 MW for ocean power.

The initial plan being studied by the DOE is to increase the installation target for wind projects by another 50 to 60 MW to increase the allowed capacity to as much as 300 to 310 MW. The installation target for solar projects may also be increased by another 30 MW to a total of 80 MW.

According to Layug, the reallocation was meant to address the oversubscription on the two particular resources. This means many of the proponents have wind and solar projects whose total capacities are much higher than the allocated installation targets.


Feed-in Tariff (FiT) to be issued by March 2011

From Philippine Star, Wed. February 16, 2011, page B-8, by Ms. Donnabelle L. Gatdulla

The Philippine government thru the National Renewable Energy Board (NREB) is targeting to come up with the feed-in tariff (FiT) rate scheme by the end of March this year (2011), a top Department of Energy (DOE) official said.

The FiT is the price per kWh sold that will be paid to all renewable energy (RE) developers and power generators for putting up these intermittent power generation plants. It shall be fixed for 15 years and shall be subject to review every 3 years with the possibility of lowering the FiT as technology and economy of scale improves. It is, however, prospective, and applies only to future RE projects, thus protecting the earlier RE investments from regulatory and pricing risks arising from technological improvements. The RE technologies being intermittent are thus considered must run and will be dispatched when available and transmission and distribution system operators are obliged to ensure that investments are made to ensure their safe and stable connection into the grid.

The FiT is paid to the RE developers by the TRANSCO (National Grid Corporation of the Philippines or NGCP) who provide the metering and transmission services to the distribution utilities (DUs) and electric cooperatives (ECs). In turn, the DUs and ECs collect the renewable energy charge (REC) as a pass-thru charge from the end-consumers such as industrial, commercial, residential, public and street lighting and agricultural consumers. The FiT is uniform throughout the country but specific for each technology and certain capacity range in cognizance of the technological and economic differences due to plant capacity or size.

The REC is calculated by the ERC based on the total FiT payments to RE developers (Peso/kWh x kWh generated by RE) / (kWh sales of all DUs and ECs). The NREB prepares the RE Development Plan and using the projected kWh generation and sales it calculates the total FiT payments to all RE developers. Then the NGCP provides the annual sales to all grids (Luzon, Visayas andMindanao) and divides the total Fit payments to arrive at a uniform REC to be collected similar to the universal levy from all consumers and private generators in the country.

“By end of March, it will happen. There is already submission of initial numbers at the Energy Regulatory Commission (ERC)” said the DOE official.

Public hearings have been scheduled all over the country after applications from the NREB for FiT have been received by the ERC.

Meanwhile, the DOE is set to conduct regional public consultations for the rules governing the establishment of the renewable portfolio standards (RPS) nationwide. The rules to be reviewed will identify among others the installation targets for all RE resources in accordance to the National RE Program.

The first consultation will be held inBacolodCityin the Visayas on Feb. 16, followed by Laoag City in Northern Luzon on Feb 21, Cebu City in the Visayas on Feb 23, Cagayan de Oro City in Northern Mindanao on Feb 24 and Davao City in Southern Mindanao on Feb 25.

The RPS is a market-based policy that requires the electric power industry participants such as distribution utilities (DUs) and RE generators and suppliers/aggregators to source an agreed portion (say 10%) of their energy supply from eligible RE resources.

The purpose of the FiT and RPS as envisioned in Republic Act no. 9513, known as the “Renewable Energy Act of 2008”, is to contribute to the growth of the RE industry by diversifying energy supply, spur socio economic development in rural areas (agri-based fuels for biomass power plants, mini-hydro), and help address environmental concerns in the country by reducing harmful emissions from fossil fuels (pollutants SO2, NOx, particulates, heavy metals; green house gas emission CO2).

The preliminary calculations show the FiT to be in the order of magnitude below. These are not official ERC or NREB numbers and are based on initial calculations of this energy technology expert:

Table I.  PROPOSED FITs

Technology

Fuel/Capacity

Size of    Representative Project

Proposed FIT    (Php/kWh)

Biomass

2.  Waste to Energy Livestock Wastes

1.0 MW

7.85

3.  Waste to Energy Municipal Wastes

8.3 MW

2.  Mini Hydro 100 kW < Capacity < 10 MW

8 MW

3.  Small Hydro  10MW < Capacity < 50 MW

24.85

Wind
1.  Residential Capacity <= 100 kW

12.75

2.  Commercial Capacity > 100 kW

30 MW

10.75

 

The above table was calculated using the following assumptions:

1) Capital structure of 30% equity and 70% debt of total project cost

2) Minimum equity returns by investors of 16% p.a. and commercial rate of lenders of 10% p.a. to encourage investment  in RE

3) Provision for transmission line capital recovery as part of the project cost (e.g. biomass 10 km, mini-hydro 20 km, solar PV 10 km, wind 20-35 km, ocean thermal 10 km)

4) Use of 69kV transmission line at a cost of P2,000,000 per km depending on conductor

5) Transmission line losses calculated based on phase, length, type of conductor, etc.

6) Installed equipment cost estimate based on: FOB $/kW, ocean freight 5% of FOB, insurance 1% of FOB, VAT 12% of CIF, customs duty 0% of CIF and VAT, local freight cost 3% of CIF, installation cost 5% of FOB, contingency 10% of EPC, documentary stamps 1% of EPC, economic life for FiT recovery 15 years, salvage value 10%, project development cost 2% of land and fixed assets

7) Working capital requirements: 2 months fuels and equipment spares, 3 months utilities, 3 months maintenance of rest of plant, 3 months personnel expense, 1 month land lease/rent, 1 month taxes, insurance and services, and 1 month transportation expenses

8) Interest during construction: loan arranger fees 1% of amount to be financed, modeler and legal fees 1% of amount to be financed, commitment fees 0.5% of un-drawn loan, interest during construction 8% p.a. or 8/12% per month of drawn amount

9) The total project cost is sum of installed equipment cost, working capital requirements and interest during construction

10) Variable O&M costs of 0.00027 $/kWh (sample for wind from Power Generation Technology)

11) Fixed O&M costs of 0.0853 $/kW/year (sample for wind from Power Generation Technology)

12) Debt service reserve (DSRF) fund of 6 months of debt (principal and interest)

13) The DSRF is deposited in a FCDU earning 4% p.a.

14) Final tax on foreign currency deposit (DSRF) 7.5%

15) Special privilege tax of 1% of electricity revenue

16) Special realty tax of 1.5% of depreciated project cost

17) DOE 1-94 of 0.01 PhP/kWh electricity sale

The reader is advised to get in touch with the technology expert for assistance in calculating their particular feed-in tariff and in the conduct of energy resource assessment, capital and operating cost estimates, and feasibility studies to determine the first year electricity tariff (FiT), levelized generation cost breakdown and profit, and economic returns (project and equity IRR, project and equity payback, project and equity NPV). The model includes also a report on the income and expense statement, balance sheet and statement of cash flows needed by the bank for evaluation purposes.
