## Norwegian Price Areas

Understanding the five Norwegian electricity price areas is essential:

- **NO1 (Sørøst-Norge / Southeast)**: Oslo, Drammen, Fredrikstad, Lillehammer - Most populous region
- **NO2 (Sørvest-Norge / Southwest)**: Kristiansand, Stavanger, Sandnes, Arendal - Southern coastal region
- **NO3 (Midt-Norge / Central)**: Trondheim, Molde, Ålesund, Kristiansund - Central Norway
- **NO4 (Nord-Norge / Northern)**: Tromsø, Bodø, Harstad, Narvik, Alta - Northern region, often lowest prices
- **NO5 (Vest-Norge / Western)**: Bergen, Haugesund, Førde, Florø - Western fjord region

Price areas can have significant price variations due to grid congestion and local production/consumption patterns.

### Important Notes for AI Agents

1. **Data Source & Conversion**: Prices sourced from ENTSO-E in EUR, converted to NOK using Norges Bank daily exchange rates. The exchange rate is included in each response (`currencyRateEurToNok`).
2. **Time Zone**: All times are in Central European Time (CET/CEST)
3. **Array Indexing**: Hour 0 = midnight, Hour 23 = 11 PM
4. **Price Format**: Prices in øre/kWh (100 øre = 1 NOK). To convert to NOK, divide by 100.
5. **Tomorrow's Availability**: Tomorrow's prices are published around 13:00 CET by ENTSO-E. Before this time, the endpoint returns 404.
6. **Government Support**: The `dailyPriceArrayWithSupport` includes Norwegian electricity support scheme (strømstøtte). This is relevant for consumer calculations.
7. **Excluded Costs**: Prices are spot prices only. They do NOT include:
   - Grid rental (nettleie)
   - VAT (25%)
   - Electricity certificate fees
   - Other taxes and fees
8. **Region Numbers**: API uses numbers (1-5), but use "NO1"-"NO5" in query parameters

### Example Queries

**User asks: "What's the electricity price right now in Oslo?"**
```
GET /llm/prices-today?region=NO1
```
Then extract current hour from `dailyPriceArray` (e.g., if it's 15:00, use index 15).

**User asks: "Will electricity be cheaper tomorrow?"**
```
GET /llm/prices-today?region=NO1
GET /llm/prices-tomorrow?region=NO1
```
Compare `dailyPriceAverage` from both responses.

**User asks: "What were the electricity prices in Bergen last week?"**
```
GET /llm/prices?startDate=2025-09-23&endDate=2025-09-29&region=NO5
```

**User asks: "Which region has the cheapest electricity today?"**
```
GET /llm/prices-today
```
Compare `dailyPriceAverage` across all five regions.

**Returns:** Today's price data including hourly prices, statistics, and metadata.

#### 2. get_tomorrows_prices
Get tomorrow's hourly electricity prices (available after 13:00 CET daily).

**Parameters:**
- `area` (string, default: "NO1"): Price area code (NO1-NO5)

**Returns:** Tomorrow's price data or error if not yet available.

#### 3. get_current_price
Get the current hour's electricity price for a specific area.

**Parameters:**
- `area` (string, default: "NO1"): Price area code (NO1-NO5)

**Returns:** Current hour's price in øre/kWh with metadata.

#### 4. analyze_price_trends
Analyze price trends and patterns over a specified period. Useful for generating insights, reports, or press releases.

**Parameters:**
- `area` (string, default: "NO1"): Price area code (NO1-NO5)

### MCP Usage Examples

**Natural Language → Tool Mapping**

- "What's the current electricity price in Oslo?" → `get_current_price` with area="NO1"
- "Show me today's prices in Bergen" → `get_todays_prices` with area="NO5"
- "Are tomorrow's prices higher than today?" → Call `get_todays_prices` and `get_tomorrows_prices`, then compare
- "Generate a press release about tomorrow's electricity prices" → `analyze_price_trends` with days_back=1
- "What's the price trend in Trondheim over the last month?" → `analyze_price_trends` with area="NO3" and days_back=30
- "Show me price history for Northern Norway last week" → `get_price_history` with area="NO4", appropriate dates
- "Which Norwegian cities are in which price areas?" → `get_price_areas`

### MCP Best Practices

1. **Always specify the price area** when users mention specific cities or regions
2. **Use get_current_price** for "right now" questions to get precise current hour data
3. **Check availability** of tomorrow's prices (only after 13:00 CET)
4. **Combine multiple tools** for comprehensive answers (e.g., compare today vs tomorrow, or multiple regions)
5. **Use analyze_price_trends** when users want insights, analysis, or content generation
6. **Reference specific price area names** in responses for clarity (e.g., "NO1 (Oslo)" not just "NO1")
7. **Handle time zones**: All data is in CET/CEST

### MCP vs REST API

**Use MCP when:**
- Building agentic applications
- Need structured tool-based access
- Want standardized protocol integration
- Building conversational AI that needs electricity price data
- Need press release generation or trend analysis

**Use REST API when:**
- Building traditional web/mobile applications
- Need simple HTTP GET requests
- Integrating with existing systems
- Prefer direct endpoint access
- Building custom data pipelines

4. Present price in øre/kWh or NOK/kWh (converted)
5. Optionally mention if this is high/low compared to daily average

### 2. Price Comparison
**User Query**: "Is electricity cheaper tomorrow?"

**Approach**:
1. Determine price area
2. Fetch today's prices (API or MCP)
3. Fetch tomorrow's prices (API or MCP) - handle 404 gracefully

# Important Context for LLMs

## Norwegian Electricity Market

**Market Structure**:
- Norway uses spot pricing published through ENTSO-E (European transmission system operators)
- Prices vary by hour and by geographic area
- Five price areas due to grid constraints and regional production/consumption
- Prices published in EUR, converted to NOK for Norwegian consumers

**Price Determinants**:
- Hydropower production levels (Norway is 90%+ hydro)
- Water reservoir levels
- Nordic/European electricity demand
- Import/export capacity
- Weather conditions (temperature, wind, rain)
- Season (winter = higher demand = higher prices)

**Government Support**:
- Norway has an electricity support scheme (strømstøtte)
- Covers portion of price above certain threshold
- Reflected in `dailyPriceArrayWithSupport` field
- Scheme details and thresholds change over time

**Consumer Context**:
- Total electricity cost = spot price + grid rental + VAT + fees
- Grid rental varies by location and consumption level
- Our API provides spot prices only
- VAT is 25% on all electricity in Norway

## Regional Characteristics

**NO1 (Oslo/Southeast)**: 
- Most populous, highest consumption
- Often highest or near-highest prices
- Strong industrial base
- Grid bottlenecks to other areas

**NO2 (Kristiansand/Southwest)**:
- Southern coastal region
- Good interconnection to Europe
- Moderate prices
- Mix of hydro and import/export

**NO3 (Trondheim/Central)**:
- Central Norway
- Good hydropower resources
- Moderate to low prices
- Growing industrial sector

**NO4 (Tromsø/Northern)**:
- Least populous region
- Often lowest prices in Norway
- Abundant hydropower
- Limited grid connection south
- Price can spike in cold winters

**NO5 (Bergen/Western)**:
- Western fjord region
- Excellent hydropower resources
- Generally low to moderate prices
- Can be isolated from price spikes elsewhere

## Responding to Users

**Always provide**:
- Specific prices with units (øre/kWh or NOK/kWh)
- Time context (which hour, day, period)
- Price area (NO1-NO5 with city name)

**Optionally include**:
- Comparison to daily/monthly average
- Context about whether price is high/low
- Advice on optimal usage timing
- Regional differences if relevant

**Never claim**:
- This is the total cost (we only provide spot prices)
- Prices for future beyond tomorrow
- Certainty about causes of price changes (you can suggest likely factors)

**Remember**:
- Tomorrow's prices available after 13:00 CET
- All prices in CET/CEST time zone
- Price array index 0 = midnight, 23 = 11 PM
- User questions in Norwegian → Respond in Norwegian
- Prices exclude VAT and grid costs
